Cost of Eertilizers Applied per

Acre.

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 reshipped 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 five 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 nse of the different fertilizers, it will be more convenient to have a common standard of comparison.

EXPERIMENT MADE BY REV. L. C. ADAY.
NEWBURGH, FRANKLIN COUNTY.

Soil, Red Cedar Land; Sub-soil, Red Clay. By examining the following statement of Mr. Aday's work for 1892, and comparing it with the experiments made by him for 1891, it will be seen that the general indications are that his soil is deficient in the three main elements of plant food, as plot No. 9, where a complete fertilizer is used, gives the best results for both years. When floats in combination with nitrate of soda and floats with green cotton seed are compared it is in favor of floats with green cotton seed in 1891, and floats with nitrate of soda in 1892.

EXPERIMENT MADE BY MR. M. A. BISHOP,
MADISON, MADISON CUUNTY.

Soil, Dark Loam; Sub-soil, Clay. In Mr. Bishop's experiments for 1891, plots number 6 and 9 give the same yield, and plot number 16 gives 256 lbs. less than either, but the same as plot number 3, while in his experiments for 1892, plot number 6 gives 128 lbs. less than plot number 9, plot number 16 gives 64 lbs. more than plot number 6, and 128 lbs. less than plot number 9, and 192 lbs. more than plot number 3. The results are so conflicting that no conclusion can be drawn. Floats with the nitrate of soda gave best results in 1891, but in 1892 the combination is in favor of floats with green cotton seed.

9 EXPERIMENT BY MR. F. W. BRADLEY.
WALKER SPRINGS, CLARKE COUNTY.

Soil,

Sandy; Subsoil, Red Clay.

The best results obtained by Mr. Bradley in his two years experiments are from the use of cotton seed meal with acid phosphate.

In 1891 plot i o. 16 gave 276 pounds more than plot No. 9, and 1892 it is '288 pounds more. These results are very decided, and show that it is a waste of money for Mr. Bradley to use potash on his soil. Green cotton seed with floats give better results than nitrate of soda with floats, and for two years give larger yield. than
complete fertilizer. To purchase a fertilizer which
is a waste of money for Mr.
1892it i

10 EXPERIMENTMADE BY D. L. BROWN,
RANDOLPH, BJBB COUNTY.

Soil, Sandy; Sub-8oil, Clay.
While Mr. Brown's experiments were injured in 1891 by drought and overflow, yet when plot Nos. 6 and 16 are compared with plot No. 9 in 1891, and the same comparison is made in his experiment for 1892, it is cleaaly seen that Mr. Brown's soil does not need-potash as his best results are obtained where nitrogen combined with acid phosphate are used and that money can be saved on such soils in buying only cotton feed meal and acid phosphate and mixwith ing them on the farm. In Mr. Brown's experiments, with nitrate green cotton seed give, better results each year than of soda.

DIXON'S MILLS, MARENGO

COUNTY.

Soil, Dark, Sandy; Sub-soil, Clay.
In Mr. Compton's experiments for two years, results are somewhat conflicting. His soil is most deficient in phosphoric acid, though the increased yield, when combined with. nitrogen, is very marked. Floats, with green cotton seed, give best results for the two years, and give only 16 lbs. less than complete fertilizer in 1892.

EXPERIMENT BY MR.A. F. CORY
MULBERRY, AUTAUGA

COUNTY.

Soil, Red. .Subsoil, Red Clay.
It is clearly shown from Mr. Cory's experiment that his soil does not need potash. Plot 6, nitrate of soda with acid -phosphate, gave 111 lbs . more than plot No. 9, complete fertilizer, while plot No. 16 gave an increase of 32 lbs. over plot No. 9. Floats with green cotton seed give better results than with nitrate of soda, and both give larger yields than complete fertilizer.

13 EXPERIMENT MADE BY R.IH. CROSS,
LETOIATCHIE, LOWNDES COUNTY.

Soil, Sandy Loam; Sub-soil, Yellow Clay.
Mr. Cross gains nothing by the use of potash on his land. In 1891 complete fertilizer gave a slight increase over plot 6, nitrate soda and acid phosphate, but yields 160 lbs. less than plot 16, cotton seed meal and acid phosphate. In 1892, plots,6 and 9 gave the indications for same. Plot 16 gave 304 lbs. more than either. the two years are that potash is not needed in this soil. Floats, with green cotton seed, gave better results for the two years than with nitrate soda.

Mr. Deer failed to make a report last year, 1891, so we have only this year's work to compare. It is evident from this experiment for one year that it is a waste of money to apply potash as in plot 9 on land like Mr. Deer's.

COUNTY.

Red Sandy Loam; Sub-soil, ed Clay.

In Mr. Johnson's two years experiments it is clearly shown by the increased yield of plot No. 2"over-1 and 3, that phosphoric acid is the element most deficient in his soil, but in combination results are conflicting. In 1891 plot No. 9 gave 128 pounds more than plot- No. 6, while in 1892 plot.6 gives 352 pounds increase over plot No. 9. Floats, with green cotton seed, give the best results in 1891, while with nitrate of soda give best results in 1892. Further experiments are necessary to be made on this soil before any conclusions can be drawn.

21 EXPERIMENT MADE BY J. C. KILLEBREW,
NEWTON, DALE COUNTY.

Soil, Sandy Loam;

Sbsoil, Red

Clay.

In Mr. Killebrew's experiment for 1891, nothing is gained from the use of acid phosphate, as is shown when plot No. 6 is compared with plot No. 9, while in 1892 it is clearly seen that phosphoric acid is the leading element needed.' The increase of plot over average of unmanured plots 4, 8 and 12, 256 pounds per acre. -Plot No. 6 gives an increase of 288 pounds, and plot 9 gives, 576 pounds increase. The results from plot No. 16 are very mrarked. In 1891 the iflcrease over plot No. 9 is 16 pounds, but in 1892 it is 160 pounds per acre. Floats with green cotton seed, and floats- with nitrate of soda, give same results in 1891," but 1892 with green cotton seed give 544 pounds more than floats with nitrate of soda, but no more than green cotton seed alone, as in plot No., 13. i ov seI.~.c. !r 12 Tha

CLANTON, CHILTON COUNTY.

Sandy; Sub-soil, Red Clay.

It is clearly shown by the results of two years' experiments made by Mr. Logan that his soil does not need potash. In 1891 plot 6 gave an increase over plot 9 of 112 pounds, and over plot No. 16 48 pounds; while in 1892 plot No. 6 gave 16 pounds more than plot No. 9, and 8 pounds more than plot No. 16. These. amounts are small but they are valuable facts, and show that it is a waste of money to use potash on such soils, as the yield of. cotton is decreased. It should be stated here that cotton seed meal contains some potash, is why the comparison is made between plot No. 6 'and plot No. 16. Floats with green cotton seed gave with nitrate of soda. better results for the two years than

EXPERIMENT MADE BY J. W. PITTS,
CRESWELL STATION, SHELBY COUNTY.

Soil, Thin Brown or

Iclatto; Subsoil, Ste fClay.

In this experiment it is clearly shown in two years' results that potash is not needed in this soil. Comment seems unnecessary. In 1891 plot No. 6 gave an increase over plot No. 9 of 48 pounds, and plot 16 gave 112 pounds more than plot No. 9. In 1892 plot No. 6 gave 208 pounds. more than plot No. 9, and plot No., 16 gave 192 pounds. more than plot No. 9. These are not large amounts,
but

they

are hard facts,.and Mr. Pitts is wasting money when he

buys potash for his soil. Floats with green cotton seed give best results in 1891, while with nitrate of soda give an increase in 1892.

29 EXPERIMENT. MADE CY S. A. PRUITT, CHESS, PIKE COUNTY. Soil, Light Sandy; Sub-soil, Red and Yellow Sandy. The best results in this experiment for the two years are from plot 16-cotton seed meal with acid phosphate. Plot No. 9,'complete fertilizer, gave a marked increase over plot No. 6 for each
year, and the indications are that the soil is deficient in the three main elements of plant food. Floats with green cotton seed give -a decided increase over floats with nitrate'of- soda for the two years

30 EXPERIMENT MADE BY J..II. RADNEY, ROANOKE, RANDOLPH COUNTY.
Soil, Sandy Loam; Subsoil, Clay. Results of Mr. Radney's experiments are so conflicting that further work will have to be done before any conclusions can be drawn. His best results in 1891 are from plot No. 6, nitrate of soda with acid phosphate; whije in 1892, plot No. 9, complete fertilizer, gives 136 pounds more than plot No. 6, and plot 16 gives an increase of 398 pounds over plot No. 6. floats with nitrogen are eompared, with nitrate of soda give best results in 1891, while floats with green cotton seed give best results in 1892.
