In order that the experimenters and other farmers may better understand the inquiry made upon the different plots, the cost of the different materials used is given in the statement which follows. The calculations are made upon the cost laid down at Auburn. The local freights upon the packages re- shipped to the depots of the experimenters would produce a false impression, since the average local rate of freight charged upon the amount sent to each experimenter from Auburn to their depots exceeds dollars per ton. Shipped in quantity, the freight to the various depots of the experimenters would average little more than that from the factories to Auburn. Again, in estimating profits resulting from the use of the ferent fertilizers, it will be more convenient to have a conmon standard of comparison. five dif- Quantity and Cost per Acre of Fertilizers used by Cooperative Soil Test Experimenters, 1891.

In addition to the co-operative experiments already mentioned, Mr. A. F. Cory, Mulberry, Autauga county, an Alumnus of the A. & M. College, conducted some special nitrogen, potash and intercultural experiments. EXPERIMENTS MADE BY REV. L. C. ADAY, NEWBURtGH, FRANKLIN COUNTY. Soil, Red Cedar Land-Sub-Soil, Red Clay. Average yield of unmanured plots 611 pounds per acre. By adding the yield of plots 4, 8 and 12, and dividing the amount by 3, we have 611 pounds average yield per acre of unmanured plots, which serves as a basis for comparison for this as well as the following experiments. It is interesting to note the effects of different fertilizers upon the maturity of the cotton plant in this experiment, which can be seen from dates of picking. Mr. Aday cultivated this crop throughout with heel scrape. The general indications from the results are, that the soil needs nitrogen, phoiphoric acid and potash. By reference to plot number 9, a complete fertilizer, the largest yield is observed, except in plot number 15, stable manure, which contains phosphoric acid and potash to a certain extent, in combination with nitrogen. The yield in plot No. 14, green cotton seed and floats, is very marked. The following tabulated statement is the result of Mr. Aday's experiment : o a-+ Lbs. Fertilizers per Plot. Lbs.

BEASELY, RED LEVIEL, COVINGTON Soil, COUNTY. Clay. Red-Sab-8oil, Average yield of unmanured plots, 325 pounds per acre. Mr Beasely reports that he cultivated his cotton according to instruc- tions in Bulletin No. 12, which contains directions for all experimenters alike. The indications are, from the following staterment, that phosphoric acid is the principle element needed in this soil. By observing the yield of each unmanured plot, it will be seen that there is a want of uniformity in the soil of this test acre. O ' v -' Jr-,O v " f~ ~~ J%0oint in 0ies Lbs.

Soil, Clay Loam-Sub-soil, Stif Clay. Average yield of unmanured plots, 312 pounds per acre. Mr. Bishop in his report says, owing to drought he did not get a stand of cotton until the 5th of June. The seasons were perfect from the time the cotton came up until July 27th, after which time no rain fell for three months. The unfertilized plots did not make an average crop on account of the late date of its coming up, fully 10 per cent. of the bolls being destroyed by frost. Mr. Bishop calls especial attention to the fact, that the use of fertilizers is necessary to hasten the maturity of the crop. Cultivation was thorough. The slight increase in plot number 4 is explained by the removal of rocks and chunks piled on it the previous year. This ground has been in cultivation since 1857. Lbs. Fertilizers per Plot. Lbs.

T. W. BRADLEY, WALKER SPRINGS, CLARKE COUNTY. Soil, Sandy-Sub soil, Clay. Average yield per acre of unmanured plots 381 pounds. From Mr. Bradley's report, it will be seen that this test acre is not of even fertility as is shown by comparing unmanured plots 4, 8 and 12, among themselves. By noticing the yield from use of fertilizers applied singly, and in combination, it is evident that this soil is lacking in all three main elements of plant food, while acid phosphate is needed most of any. As a rule, plants are not fastidious from what source they obtain nitrogen, yet by comparing plot phosphate and nitrate soda-with plot phosphate and seed meal --the influence of nitrogen in the cotton seed meal in ton 16-acid 6-acid cot- plot 16 seems to be effectual in giving better results. By comparing plot 11, nitrate soda and with plot 14, cotton seed and the results are in favor of plot 14. These are not positive conclusions, but in this experiment the indications are as above stated.

Mr. Brannon says the land on which this test was made has been in cultivation for forty years, and is known as "poor sandy land." For the last twenty years it has been slightly fertilized each year with cotton seed. In securing a stand of cotton, no trouble was experienced and the cultivation was thioroughi. needed as is shown in plot No. 9, which contains the three leading elements of plant food. No benefit is derived from the use of but the results from acid phosphate and cotton seed meal in plot decided.

Mr. Compton says that he has been cultivating this land for the last twenty years, manuring lightly each year with green cotton seed. The seasons being so unfavorable for seed to germinate that he did not get a stand at the proper time and the consequence was had to plant over, and did not secure a stand until June 1st. After June 1st every thing was propitious to the growth of the plant until September after which time no rain fell until Novembr 9th, which dry spell materially affected its maturity on account of the lateness of getting a stand. The yield from acid phosphate alone in plot 2, is very striking in this experiment, and in combination with nitrate soda on plot 6, the r'esults are nearly as great as in plot 9 where a complete fertilizer was used. Attention is called to the increased yield of ,floats in plot No. 10, over acid phosphate in plot No. 2, in combination with green cotton seed in No. 14, the yield is greater than in plot No. 9, a complete fertilizer. The indications are that this soil is deficient in phosphoric acid.

R. I. CROSS, LETOHATCHIE, LOWNDES COUNTY. Soil, Sandy Loam--Sub-soil, Yellow Clay. Average yield of unmanured plots, 352 pounds per acre. The uniform fertility of this experiment acre is about as good as is usually found. By comparing the yield from plots 1, 2 and 3, with the average yield of 'unmanured plots 4, 8 and 12, it will be seen that the increased yield from plots 1 and 3, is greater than from plot 2. In plots 5, 6 and 7 where the elements are in combination, the yield in plot 5, is less than in 6 and 7, while in plot 9, a complete fertilizer, the increase over the average of unmanured plots is 384 pounds. Plot 10, floats alone, gives an increase over no manure of 80 lbs., while in combination with nitrate soda, in plot 11, the increased yield is 288 pounds, and with green cotton seed in plot 14, the increased yield is 336 pounds. This experiment would indicate that floats can be used with satisfactory results on the soil selected by Mr. Cross. By referring to plot 15, stable manure, it will be observed that there is a falling off in yield, while in plot 16, acid phosphate and cotton seed meal, the yield is very satisfactory. o S Lbs.

DAVIS, PRATTVILLE, AUTAUGA COUNTY. Soil, Sandy Loam--uu-Soil, Red Clay. Average yield per acre of unrnanured plots 695 lbs. Mr. Davis says in his report, that nitrogen is the element most needed in his soil, which is the general indication from results of his experiment. While the increased yield in plot 9, a complete fertilizer, is 135 lbs. over plot 1, nitrate soda, yet in comparison with plot 13, green cotton seed, and plot 15, stable manure, the results point to nitrogen as the chief element lacking. By comparing unmanured plots 4, 8 and 12, with each other, an increase is noticed in each snccessive one. For instance, the difference in yield between plots 4 and 8, is 30 lbs., and between 4 and 12, 75 lbs., indicating an .uneveness in the fertility of this acre. If this be a fact, the increased .yield from use of floats in plot 10, over acid phosphate in plot 2, is accounted for. The foregoing being true, the increase of plots 11, 14 and 16 is also explained. Further experiment, however, is necessary to establish a conclusion. Too much care cannot be exercised in selecting soil of uniform productiveness for experiment. .~+ " Lbs. Fertilizers Per Plot. f °-I l Lbs. Fertilizers o o , 'P-, per Acre. " " '.

R. M. DICK, ATTALLA, ETowAII COUNTY. Soil, Red Loam-Sub-soil, Red Clay. Average yield of unmanured plots 240 pounds per acre. We have in this experiment a fact noticeable in other experiments, which is, that while several elements taken separately and applied to the soil are not beneficial, and even in some instances, decrease the yield from unmanured plots, yet, when the same are combined the results are very desirable. For instance, the average yield of unmanured plots 4, 8 and 12 being 240 pounds per acre, plot No. 1, nitrate of soda alone, gives 40 pounds less than average of no manure. But in plot No. 6, in combination with acid phosphate, the increased yield over plot No. 2, acid phosphate alone, is 384 pounds. It will be observed that plot No. 2, acid phosphate, gives an increase of 376 pounds per acre over no manure. Furthermore, by comparing plots Nos. 3, 5 and 9, where muriate potashi was used, its effects were injurions rather than beneficial. While the increased yield from use of in plots Nos. 10, and 14, is not as great as from the use of acid phosphate in plots 2 and 6, still, the result is satisfactory, taking into conside ation the difference in the cost of the two fertilizers. From the foregoing, it will be seen that phosphoric acid and nitrogen are the main elements needed in this soil. 11 floats ccl 3 >21'2 ^ bj ,C v oJJ is.s' vp GV G bO O0 t Lbs.

R. T. EWING, RoUND MOUNTAIN, CHEROKEE COUNTY. yield unmanured plots per acre, 320 pounds. In this experiment, no perceptible benefit is seen from the application of nitrate soda in plot No. 1, and while there is shown a slight increase in plot No. 3, muriate potash, over no manure, it is no greater in this instance than occurs in the unmanured plots 4, 8 and 12. In plot No. 2, acid phosphate, there is an increased yield of 160 pounds over average of no manure. By comparing plot No. 6 with plot No. 9, potash is of no value in this combination; but it is shown that Average Soil, Gray, Sandy, Piney Woods-Sub-soil, Yellow Sand. in plot No. 7, combined with acid phosphate, the increased yield is 192 pounds over acid phosphate alone in plot No. 2. The increased yield from use of in plots 10, 11 and 14 over the average of no manure, while not as great as in somne instances, is satisfactory.

M. HOBDY, LOUISVILLE, BARBOUR COUNTY. Soil, Sandy Loam-Sub-soil, Red Clay. Average yield, no manure, 725 pounds per acre. By noticing the yield from the unmanured plots 4, 8 and 12, a lack of uniform fertility of the soil is the first thing to be readily observed. It is to be noticed furthermore, in this report, that the soil is lacking in every principle element necessary for plant food, and that no one taken separately increases the yield, but by putting two ingredients together (one of the ingredients being acid phosphate), as in plots 6 and 7, a satisfactory result is developed, compared with No. 5. In plot No. 10, floats, the increased yield over no manure is 75 pounds, which difference is not so great as between the unmanured plots 8 and 12, it being 160 pounds, and which result should not be misleading. This is another instance of the importance of having land of uniform fertility for conducting experiments. Mr. Hobdy says he exercised great care in making this experiment, yet, the irregularity of the soil alluded to above, as is shown by results, suggests great pains in selecting an acre of as even fertility as possible. 0 P- Lbs.

EXPERIMENT MADE BY MR. WM. B. HALL, LOWNDESBORO, LOWNDES COUNTY. Soil, Lime Prairie. Sub-soil, Black Clay. Average yield, no manure, 341 pounds per acre. Mr. Hall says that the land selected for this experiment has been in cultivation about 50 years, and is called old prairie. It was thoroughly prepared and cultivated. The third picking was lost by a raid from cattle breaking in, and while the yield from this picking might have been small, yet the.loss of it vitiates the experiment as no accurate conclusions can be arrived at. The following tabulated statement shows the results obtained, and it indicates that the soil is deficient in all three elemenis of plant-food. Further investigation is necessary to come to a conclusion: tO " - Q 0 O 0 PZ Lbs. Fertilizers per Plot. Lbs.

Mr. Inzer says that the land on which this experiment made has been in cultivation five years. Owing to unfavorable seasons, a good stand of cotton was not obtained until the 10th of June. Although the cultivation varied from instructions, yet the results was show that the soil is deficient in the chief elements of plant food as is shown in plots 5, 6, 7, 8 and 9. By comparing the unmanured plots 4 and 12, it will be seen that this acre is not uniform in productiveness, yet the increased yield from floats, nitrate soda and green cotton seed, in plots 10, 11, 13 and 14 is satisfactory. However, cotton seed meal and acid phosphate in plot 16, give the best results. be0. se.- uI 4' ,h 54 9 an Lbs. Fertilizers per Plot, Lbs.

URIAH JOHNSON. TRINITY STATION, MORGAN COUNTY. Soil, Red Sandy Loam-Sub-soil, Red Clay. Average yield of unmanured plots, 384 lbs. per acre. Mr. Johnson having given in his report the average yield per acre of the unmanured plots, 4, 8, and 12, placed the same amount opposite each plot, there is no data left by which the uniform fertility of this acre can be determined. Mr. Johnson writes that he did not get a stand of cotton until June 6th, on account of drought, and consequently thinks his crop not so good as it would have been, had the seed come up in due time. From the results of this experiment, the leading element needed in this soil is phosphoric acid. The average yield of unmanured plots, 4, 8 and 12, being 384 lbs. per acre, the increased yield on plot 2, acid phosphate is 416 lbs. over no manure. And it will be further noticed, that while acid phosphate in combination with nitrate soda as in plot 6, or with mnuriate potash in plot 7, gives satisfactory results, yet the yield proportionately is not so great as from the use of acid phosphate alone. By comparing plot 9, a complete fertilizer, with plots 6 and 7, it will be seen that the additional use of nitrate soda has added nothing to the increased yield over plot 7, whereas plot 16, cotton seed meal and acid phosphate, has given the best results in this experiment. If the fertility of this acre be uniform, the increased yield from the use of floats in plots 10, 11 and 14, points to a lack of phosphoric acid in this soil, which in combination with nitrogen as in plots 11 and 14, shows an increased yield. The nitrogen in plot 11 being more readily available as plant food, is not retained in the soil as in green cotton seed in plot 14, which may explain the difference in these two plots. As a rule, plants are not fastidious from what source nitrogen comes, just so its supply is sufficient. 0 a O Lbs.

J. C. KILLEBREW, NEWTON, DALE COUNTY. Soil, Sandy Loam-Sub-soil, Red Clay. Average yield of unmanured plots per acre, 464 lbs. Mr. Killebrew says in his report that the land from which this experiment acre was selected has been in cultivation 15 years, is very poor, and even after lying out for the past 2 years, vegetation was very scant. He says ho is satisfied that his land needs more nitrogen than is found in standard fertilizers, which are the indications from this report. In plot No. 1, nitrate soda, there is an increased yield of 80 lbs. per acre over average of no manure In plot 2 acid phosphate, the yield is the same as no manure. In plot 3, muriate potash, the yield is 176 lbs. less than average of no manure. Plot 5, a combination of nitrate soda and muriate potash, gives a striking increase over average of no manure, while plot 6, nitrate soda and phosphate and plot 7 muriate potash and phosphate show a very small increase over no manure. In plot 9, the three elements, show about the same results as in plot 5, where nitrate soda and muriate potash are used; but by comparing plot 5 with plot 16, the indications are, that acid phosphate in combination with cotton seed meal gives satisfactory results. By reference to plot No. 10, floats, the yield is 64 lbs. per acre less than the average of no manure, while in plots 11 and 14, by the addition of nitrogen, the yield is increased 144 lbs. per acre over no manure. In plot 15, stable manure, the best results are obtained, which also indicate the need of nitrogen in this soil. Attention is called to the uniform fertility of this experiment acre. oC O Lbs.

Soil, Red-Sub-soil Red, Stiff Magnetic Iron. Average yield of unmanured plots per acre, 389 lbs. Attention is called to the irregular fertility of this acre-plot 4 yielding 256 lbs. per acre, plot 8 400 lbs. and plot 12,512 lbs., the average being 389 lbs. without manure. Mr. Kennedy says: to very unpropitious seasons, this experiment is not as satisfactory as it would have been, had the seasons been favorable. Cotton was planted April 19th- care up June 19th and was not put to a stand until July 10th." The indications are that plot No. 9, a complete fertilizer, gives the best results in this experiment, as the soil seems deficient in all the chief elements of plant food, though the increased yield from acid phosphate and nitrate soda in plot 6, and acid phosphate and muriate potash in plot 7, is very satisfactory. In plot 10, floats alone, an in'creased yield is shown, notwithstanding the lack of uniform fertility of the soil and by the addition of nitrogen as in plot the increase yield is still further advanced. Attention is directed to the following falling off of stable manure in plot 15, and when plot 16, acid phosphate and cotton seed meal is compared with plot 9, the results are not so good as from a complete fertilizer in No. 9.

J. A. LOGAN, CLANTON, CHILTON COUNTY. Soil, Mulatto and Saidy--Sub-soil, Red Clay. Average yield of unmanured plots, 509 lbs. Mr. Logan states that he prepared and cultivated this test acre thoroughly, and made as many as three careful observations on the growth and maturity of the plant the use of fertilizers. Attention is called to the uniform fertility of the soil, by observing the yield of the unmanured plots 4, 8 and 12. The increased yield over no manure from the.use of acid phosphate in this soil, is very decided, as is shown in plot 2, giving 363 lbs., and in plot 6, in combination with nitrate soda the increase is 475 lbs. over no manure, giving better results than acid phosphate alone. It will be seen by referring to plots 3, 5, 7 and 9 and com- from paring them with plot 2, no potash. From the use of floats in plot 10, we have an increase over no mawe have an nure of 131 lbs., and by the addition of nitrate soda as in plot increase of 235 lbs. and in plot 14, floats and green cotton seed combined, we have an increase of 281 lbs. The increased yield from the use of floats is not so great as from ascid decided benefit is derived from the use of muriate 11, "v ¢ the results are satisfactory. The yield from stable manure in plot 15 is very marked, and from cotton seed meal and acid phosphate in plot 16, the result is as great as could be expected when compared with plots 9 and 10. v\hr\nv\hrJtn alr\~~n It r~t Fl~na i onv phosphate; but when the cost of the. two are compared, sebiJee r" b. r.

W. H. MILLER, UNION, GREENE COUNTY. Soil, Sandy-Sub-soil, Clay. Average yield per acre of unmanured plots, 104 pounds. By noticing the yield from the unmanured plots 4, 8 and 12, the irregularity of the fertility of this acre is plainly seen. Mr. Miller writes in making his report, that his land has been in cultivation 52 years, was never fertilized, and is very poor; and while it has been lying out for the past 4 years, the growth of vegetation was very scant. This soil is very deficient in the three main elements of plant food, as is shown by comparing plots 1, 2 and 3, where the fertilizers were applied singly, with plot 9, a complete fertilizer, where all were combined. This report certainly shows very gratifying results. The increased yield from floats in plots 10, 11 and 14, is very decided. The yield from plots 15 and 16 is nearly the same, and alike satisfactory. Much more could be said about this report, but it is so plain and decided in showing such bountiful and profitable returns from the use of fertilizers, that further cornmment is unnecessary.

J. W. MIZE, REMLAP, BLOUNT COUNTY. Soil, Red Sandy-Sub-8oil, Sticky, Mineral Nature. Average yield of unmanured plots per acre, 331 pounds. From Mr. Mize's report, it is evident that acid phosphate is the principal element needed in this soil, and that a combination of acid phos phate and nitrate soda as shown in plot No. 6, gives better results than the complete fertilizer in plot No. 9. In plot 15, stable manure, there is a marked decrease in comparison with plot 16, acid phosphate and cotton seed meal, which plot gives the greatest yield of any in this experiment. eQ. co E- E- Lbs.

MELTON, DAVIS' CREEK, FAYETTE COUNTY. Soil, White and Gray-Sub-soil Clay. Average yield per acre of unmanured plots, 245 lbs. Mr. Melton selected an acre for this experiment of almost uniform fertility as will be seen by comparing the unmanured plots 4, 8 and 12 with each other. It will be observed that this soil claims phosphoric acid as the principle element needed as is demonstrated in plot 2, and by comparing this plot with 1 and 3. By adding muriate potash as in plot 7, better results are obtained than from plots 5 and 6, but the complete fertilizer in plot 9, gives the best results of all. Floats alone in plot 10, show better results than the combination in nitrogen in plot 11; but in plot 14 in combination with green cotton seed, the increase in yield is decided. By comparing plot 15 stable manure and plot 16 phosphate and cotton seed meal, with plot 9, this result also favors a complete fertilizer. o Lbs. Fertilizers per Plot. Lbs.

W. S. MANNING, OXFORD, CALHOUN COUNTY. Soil, Mulatto-Sub-soil, Red Clay. Average yield per acre of unmanured plots, 171 lbs. It will be seen from Mr. Manning's report that acid phosphate is the element most needed in this soil which is plainly demonstrated by comparing plot 2 acid phosphate, with plots 1 and 3; and by combining acid phosphate and nitrate soda in plot 6, the results are better than from 5 and 7. By a combination of all three elements as in plot 9, the best results in the entire experiment, are shown. A slight increase in plot 10 from the use of floats is manifest, but when nitrogen is added as in plots 11 and 14, the increased yield over no manure is decidedly in favor of the combination with green cotton seed. Plot 15, stable manure, shows a decided falling off, while plot 16, cotton seed meal and acid phosphate, shows very satisfactory results. U1 F- C.) r--i o c) U1 r i etir C/1 W cc vi"I G7 O o Lbs.

J. P. OLIVER, DADEVILLE, TALLAPOOSA COUNTY. Soil, Gray Sandy-Sub-soil, Clay. Average yield per acre of unmanured plots, 432 pounds. Mr. Oliver reports that he followed instructions accurately in conducting this experiment. The uniform fertility of this acre is satisfactory. From this report, all three main elements of plant food were beneficial to the soil, particularly in a combination, as is indicated by plots 6, 7 and 9, compared with 1, 2 and 3. The increased yield from use of acid phosphate alone in plot 2, compared with the unmanured plots 4, 8 and 12, is very decided. Especial attention is called to the increased yield fl om floats in plot No. 10, being 296 pounds per acre over average of no manure, and in combination with nitrate soda in plot 11, the increased yield over no manure is 384 pounds. Comparing the nitrogenous effects with floats in plot 11, with plot No. 14, the results are in favor of green cotton seed. Plots 15 and 16, compared with plot 9, give results in favor of plot 9, complete fertilizer. o Lbs. Fertilizers per Plot. Lbs.

PITTS, CRESSWELL STATION, SHELBY COUNTY. Soil, Thin Brown or Mulatto--Sub-soil, Stiff ed Clay. Average yield per acre of unmanured plots, 317 lbs. Mr. Pitts says that the acre selected for this experiment was thin upland, which had been in cultivation 50 years, but during the last 8 or 10 years had rested and grown up in sedge. Owing to a protracted drought in the Spring, cotton did not come up until the 24th of May, and then only an imperfect stand was secured. Preparation of ground and cultivation of crop, were carried out according to instructions, Attention is directed to the uniformity of the soil in this acre, as is shown in plots 4, 8 and 12. The indications are that nitrogen and phosphoric acid are the only two elements beneficial in this experiment. There is some increase from use of potash alone in plot 3, but in combination either with nitrate soda in plot 5, or with acid phosphate in plot 7, or with both phosphate and nitrate soda in plot 9, the yield is decreased compared with plots 2 and 6. The increased yield from floats alone in plot 10, is slight, but in combination with nitrogen in plots 11 and 14, is very satisfactory. Stable manure in plot 15, and acid phosphate and cotton seed meal in plot 16, produce the best results. ( Lbs. Fertilizers per Plot. Lbs.

T. M. J. PORTER, GEORGIANA, BUTLER COUNTY. Soil, Light Sandy-Sub-soil, Red and Yellow Sandy Clay. Average yield per acre of unmanured plots, 200 pounds. Mr. Porter planted this test acre April 23rd, and failing to get a stand, replanted May 7th, in Peterkin cotton. The land was quite uniform in fertility, as is shown by the unmanured plots 4, 8 and 12. In this experiment, the soil shows a lack of all three elements of plant food, as is shown by the increased yield in plot No. 9. The use of floats in plots 10 and 14 show an increased yield, and why there should be a falling off in plot 11, cannot be explained. It will be noticed that there is a falling off in stable manure in plot 15, while acid phosphate and cotton seed meal in plot 16, give good results. vwr3~* incrase and 14so o o 2,Ic2i .s . P L4 Lbs.

Attention is called specially to the uniform fertility of this acre, and also to the increased yield from use of fertilizers, in every instance, over unmanured plots. Fertilizers, evidently are a great source of benefit to this land. 384 ---~~~MIVV V~UVUIV YI1N U~-VIJVI VIL--L1 0 I~1 O :iallyco 0 j J4-D P-4 r-.4 C) ¢0 ' . Lbs Fertilizers per Plot, Lbs.

By noticing the yield from plots 1, 2 and 3 where the fertilizers were applied singly, it will he observed that muriate potash the best results; but in combination, as in plots 5, 6 and 7, nitrate soda and acid phosphate in plot 6 give the best. In plot 9, a complete fertilizer, the yield is the same as plot 5, and less than plots 6 and 7. The yield from alone in plot 10, and in combination with nitrate soda in plot 11, is better than in plot 14 in combination with green cotton seed.

Average yield per acre of unmanured plots, 227 pounds. The uniform fertility of this acre is very marked as will be observed from the unmanured plots 4, S and 12. Mr. Stroud in his report says that instructions as to preparation of ground and cultivation of crop, were strictly carried out, and everything was favorable to the growth of the crop up to the last of July, after which time the extremely dry weather caused a general falling off, though plots 1, 2, 3, 5, 7 and 9 stood the drought better than the others. Results indicate the need of a complete fertilizer on this soil, as is shown by the increased yield in plot No. 9, which is the largest obtained. This is the only one in these experiments, except one, (by Mr. R. II. Cross whose results are about the same) where nitrate soda and acid phosphate in comnoination as in plot 6, give less results than in plots 5 and 7. Soil, Y~~AI I1 'C'llC11~5 -III~~Cll o + Lbs.

Mr. Snuggs writes in making his report, that he carefully carried out all instructions as to preparation of ground and cultivation of crop, and that great good is being done to the farmers of Culiman county from these experiments, that they are watched with great interest and that the bulletin containing his report is anxiously looked for. Special attention is called to the uniform fertility of the soil selected for this experiment. It will be seen that this soil is deficient in the three main elements of plant food, and while each gives its proper proportion, as is shown in plots 1, 2 and 3, and 5, 6 and 7, yet a culmination is found in the combined efforts of all in plot No. 9, giving 1,120 lbs.,. an increased yield of 773 lbs. over no manure. By carefully studying this report, the results are so plainly seen, that further comment seems unnecessary. ~~TIIl L 0 I~I wl It 4-D cq pr f 0 o It0 1- ot- ono ,rrn N0 n C) FP Lbs.

W.1H. SELLERS, GENEVA, GENEVA COUNTY. Soil, Sandy-Sb-Soil, Red Clay and Sand Mixed. Average yield per acre of unmanured plots, 730 lbs. Mr. Sellers writes, that the sack containing the acid phosphate for plot 2 was lost and that he was unable to obtain any green cotton seed. the experiments for plots from 1 to 9 inclusive, are vitiated. The absence of green cotton seed also vitiates the experiments with floats. It can he seen however, by reference to plot 9, a complete fertilizer, that the soil is deficient in the three main elements of plant food, No. 9 giving the greatest yield over the average of unman ured plots. fore There- sc' UT' :P-4 C11 O CO -4 c.% U O ter-, .. s. 01 0 Lbs.

M. -I ' 68R%096 40 EXPERIMENT MADE BY PRoF. DAN GILLIS, In Charge of South East Alabama Experiment Station, ABBEVILLE, HENRY COUNTY. Soil, Sandy-Sub-soil, Sand and Clay Mixed. Average yield of unmanured plots per acre, 445 lbs By noticing the yield of unmanured plots 4, 8 and 12, the uniform fertility of the soil is satisfactory. It is seen by comparing plots 1, 2 and 3 with the average of no m inure, that plot 1, nitrate soda gives no increase, while plot 2 acid phosphate gives 363 lbs. increase and plot 3, muriate potash, 67 lbs. In plot 5, nitrate soda and muriate potash, the increase over average of unmanured plots is 267 lbs. while plot 6, nitrate soda and acid phosphate, gives 443 lbs. and plot 7, muriate potash and acid phosphate, gives 411 lbs. It will be observed by comparing these plots among themselves, that acid phosphate is the leading element for producing the increased yield; but in plot 9, complete fertilizer, the increase over un. manured plots is 635 lbs. These results are very decided and satisfactory. Floats in plot 10, increases the yield over average of unmanured plots, 187 lbs., while in combination with nitrate soda, in plot 11, the increase is only 91 lbs. Still floats in combination with green cotton seed in plot 14, increases the yield over no manure, 443 pounds. Why floats alone in plot 10 should give better results than in combination with nitrate soda in plot 11, we cannot explain. The increased yield in plots 10 and 14, is very satisfactory. Plot 15. stable manure, gives the largest yield, and while the increase in plot 16, acid phosphate and cotton seed meal, is not so large as in plot 9, complete fertilizer, yet the result is quite satisfactory.

W. L. I-IATTAN, LAWRIENCE COUNTY. WHITE, Soil, Clay Loam=--Sub-soil, Red Clay. Average yield per acre of unmanured plots, 235 pounds. Mr. White's report shows another instance where nitrate soda and muriate potash applied separately, as in plots 1 and 3, decrease the yield, while in combination one with the other, in plot 5 there is a slight increase; and in combination with acid phosphate in plots 6 and 7, the increase is still greater and in No. 9, a complete fertilizer the best results in this experiment are seen. The increased yield from use of floats alone plot 10, and in combination with nitrate soda in plot 11 and cotton seed in plot 14, is very decided and satisfactory. It will be seen by comparing plots and 16,'with plot 9 a complete fertilizer, that the results are in favor of No. 9.

Mr. Cory says unfavorable weather prevented his preparing and planting this ground before the 23rd May, at which time the land was prepared with plows, harrows, &c., fertilizers applied in drill and thoroughly incorporated in soil by running a scooter plow in the furrow. Showery weather delayed the application of fertilizers for intercultural work, from June 15th to June 24th. Fertilizers intended for plot 31, to be used before planting, were over- looked and not put in until June 24th. though the experiments Mr. Cory says. "Al- are not perfectly accurate, they point to Potash does not several conclusions with some degree of certainty. seem to pay, phosphate applied alone does not have much effect, nitrogenous fertilizers in any form give an increased yield; and only nitrogenous fertilizers increase the yield, when applied interculturally."

In making his report, Mr. Cory says that the ground was thoroughly prepared, and fertilized with 100 lbs. cotton seed meal, acid phosphate and kainit each per acre, mixed thoroughly and applied in drill, before bedding. Cotton was planted in checks 3 feet each way. By noticing the number of stalks per plot, it will be seen that an uneven stand was obtained which must be considered in comparing the total yield. The cultivation was made with heel scrape throughout the entire season. The following is a tabulated statement of Mr. Cory's report EXPERIMENT WITH VARIETIES COTTON BY MR. A. F.
