BOLTE and D.T. HILL For converting swine waste to methane gas open foam-type support material, high bacterial concentrations can be retained inside the fermentation vessel. The result is faster conversion rates of organic matter to methane, enhanced capabilities for effectively utilizing dilute wastes, and generally more stable reactor operation. Since bacteria are fixed inside the reactor vessel, washout problems are minimized. This allows reduced hydraulic retention times (HRT's, the average amount of time feed material stays inside the reactor) and reduced reactor volumes, important economic considerations since initial reactor vessel cost constitutes a major portion of the investment required to set up and operate a fermentation system. Thus, because of their capabilities for effective conversion of dilute wastes at short HRT's, these reactors appear to be well suited to treatment of flushed livestock wastes and integration into refeeding/energy production systems. To evaluate the performance of these reactors using flushed swine waste, four 1.3gal. suspended particle-attached growth anaerobic reactors were set up and operated for a period of approximately 4 months. The reactor volumes were filled with reticulated open-cell polyurethane foam blocks (1/2 x 1 1/2 x 2 in.) and needle-punched nylon pads (3/8 x 1 1/2 x 2 in.) in equal portions to provide support surfaces for biofilm formation. These support particles were retained inside the fermenters using screens placed over the inlets and outlet ports of the reactor vessel. Two of the fermenters were operated at 130°F and two were operated at 95°E To simulate conditions encountered in a refeeding/energy production swine waste management system, flushed swine waste was screened to remove large particulate solids using an 18-mesh vibrating screen separator. This allowed the solid portion of the waste to be used for refeeding, with the liquid portion available for anaerobic fermentation. Previous research at the Alabama Agricultural Experiment Station has shown that approximately 50% of the potential methane present in the flushed waste remains in the liquid portion after screening. In this study, the screened swine waste liquids contained approximately 1.2% total solids, of which approximately 80% was organic material available for conversion to methane. The remaining 20% of the solid material consisted of inert ash. This flushed waste material was considerably more dilute than the 5% solids level generally considered a minimum for conventional anaerobic fermentation. The fermenters used in this study were operated over a 4-month period at a variety of loading rates. The thermophilic (130°F) fermenters were started at a 5-day retention time (HRT) and reduced progressively to 3, 2, and 1 day HRT's. HRT's for the 95°F reactors ranged from 10 to 2 days. These values can be compared to values of 5 to 20 days for conventional anaerobic fermenters. Data were taken at each HRT for gas production, gas quality (percent methane), and influent and effluent chemical parameters. The fermenters performed well at all the HRT's examined, although effluent quality began deteriorating at the shortest HRT's (highest solids loading rate). The data collected indicated that successful attachment and colonization of the support media by methane-producing bacteria occurred, and that these bacteria could be retained inside the fermenter vessel at concentrations substantially greater than in conventional anaerobic fermenters. Additionally, these reactors displayed remarkable stability, rapid response to changing loading rates, and extreme tolerance to operational upsets. Several times during the study, the entire fermenter contents were accidentally drained from the reactor vessel; however, upon recharging the fermenter with fresh waste, both 130 ° and 95 ° fermenters showed essen- cess of converting organic wastes, fermentation such as livestock manure, is the prointo methane gas, a valuable energy resource. Since the oil crisis of the early 1970's, this process has received considerable attention as a means of providing both a stable, on-site energy source and an effective waste treatment alternative for livestock producers. Conventional anaerobic fermenters consist of an airtight vessel, generally containing a mechanism for mixing the reactor contents (i.e. motor-driven paddles or recirculation pumps) and provisions for adding influent feed material and removing treated reactor effluent. The conversion of organic feed material to methane is accomplished by a diverse microbial culture termed anaerobic bacteria. These bacteria have relatively low growth rates and are sensitive to temperature, pH, and toxic materials. These characteristics have made conventional anaerobic fermenters susceptible to failure due to overloading of feed material, washout of bacteria at a rate faster than they can reproduce, or rapid fluctuations in reactor operating conditions. Additionally, influent solids concentrations of 515% are generally required for efficient conversion of organic wastes in these reactors. Unfortunately, many of the waste streams encountered in agricultural production systems are of a dilute nature (0.5-3%), and as such are not readily amenable to fermentation in conventional anaerobic reactors. Examples include animal manures collected with flushing techniques where considerable amounts of water are added to facilitate waste transport, the liquid portion of separated manures where solids are utilized for refeeding, and food processing plant wastes. This is a particular problem in swine production facilities in the Southeast, since approximately 70% of these facilities employ flushing systems for waste collection. To overcome the problems associated with conventional anaerobic fermentation, research on a new reactor technology is being conducted at the Alabama Agricultural Experiment Station in Auburn. These "Suspended-Particle-Attached Growth" reactors employ reticulated open-cell foam or needlepunched nylon particles contained within the reactor vessel to provide support surfaces for anaerobic bacteria to attach to and colonize. As the bacteria grow, they secrete a gelatinous polysaccharide material which forms a "biofilm," a thick slime layer of concentrated active bacterial mass. By trapping these bacteria in the biofilms contained within the ANAEROBIC tially no adverse effects and completely recovered within 12 to 36 hours. The results of this preliminary study indicate the suspended particle-attached growth fermenter is ideally suited for conversion of dilute animal wastes to methane gas. These fermenters were successfully operated at hydraulic retention times approximately five times shorter than those considered minimum for conventional anaerobic fermentation, which translates into smaller fermentation vessels and lower initial costs for fermentation systems. The fermenters used in this study showed a rapid start-up time and displayed extreme tolerance to operational upsets and rapid response to changing operating conditions. These characteristics indicate that suspended particle-attached growth fermenters can be successfully integrated into flushed waste and refeeding/energy production systems, providing smaller reactor vessels, enhanced stability, and adaptability to fluctuating feed scheduling and waste variability.

Many of these problems can be avoided, however, if farmers develop estate plans that take advantage of existing laws. Advantages of effective estate planning showed up in a recent Alabama Agricultural Experiment Station study of farm estate transfers. A detailed examination was made on the transfer of 10 actual estates over the period 1968-82. The study identified estate planning tools currently available for transferring a farm estate, and compared results with estate planning results during the early part of the study period. Findings of the study are illustrated by one of the estate transfers, which took place during 1977-81 under regulations of the Tax Reform Act of 1976. The example farm was a cattle and row crop operation with 2,235 acres of land. Three major objectives were addressed in the estate transfer plan cited as an example: 1. Provide for wife until her death-accomplished by leaving spouse half ownership in the land (fee simple) and a life estate in the other half. 2. Provide an inheritance for children that would be equitable and escape taxation at death of the surviving spouse-accomplished by naming children as equal remaindermen to the spouse's life estate. 3. Save taxes-accomplished by using the marital deduction, employing current-use valuation for the real property, and taking advantage of any unified credit that might be available for the estate. Provisions for "current-use valuation" of farmland allow valuing land at its value for agricultural use rather than "highest or best use" value. Use of this provision in the example estate transfer resulted in considerably lower value of the real estate portion of the estate. The result was large tax savings, table 1. The major requirement for the current-use provision is for the farm to be operated by a qualified heir. The marital deduction was another valuable tool used. This is basically a credit against the taxable estate for property which passes to a surviving spouse. Its use is spelled out in the will, with the amount of deduction determined from the amount of property passing to the spouse, in complete ownership, under the will. At the time of this farm transfer, the marital deduction was limited to $250,000, or one-half of adjusted gross estate value, whichever was larger. Another major tool utilized was the unified credit provision. At the time of transfer, this amounted to $47,000 which could be used as a direct credit against the amount of tax due for the estate.

The Economic Recovery Tax Act of 1981 offers even greater opportunities for savings in estate transfer, table 2. Savings resulted from lower land value under current conditions and larger allowable marital deductions. Under the latest law, the full value of all property transferred to the spouse will qualify for the marital deduction (an "unlimited" provision). This provision can be used to eliminate all taxes at the death of the first spouse; however, care needs to be exercised to ensure that the surviving spouse's estate does not become excessively large. The limit on "unified credit" also was raised by the latest law, making $155,800 the total available for 1986. This will exclude an estate of up to $500,000 from federal estate tax liability. As indicated by data in table 1, the farmer was generally successful in accomplishing his objectives for estate planning. The newer laws would allow even greater success, as indicated by data in table 2. Hardy is former Graduate Research Assistant and Bell isProfessor of Agricultural Economics and Rural Sociology.

RYMAL, J.L. TURNER, G.C. BARTLEY, D.A. SMITH, E. CARDEN, and R. McDANIEL leased each year and growers and new tomato varieties are regardeners are faced with a confusing array of literature proclaiming each new variety as superior to all others. In truth, tomatoes that are perfect for all climates and for all uses have not been developed. For this Alabama Agricultural Experiment Station study, 11 promising new varieties, which were released in the last 2-3 years, were compared with 7 varieties that have been popular for at least 10 years. The test was planted at the Gulf Coast Substation in Fairhope on April 5, 1985. Representative samples from each plot were picked at the firm-red-ripe stage and held in cool storage for 2-3 days, then analyzed. MANY 1 was given to the firmest tomato since firmness is desirable if tomatoes are to be shipped to distant markets. However, firmness may not be most desirable in tomatoes for the home garden. The third column indicates color, based on instrumental readings, with the highest values indicating the deepest red color of the tomato surface. Results indicate that all samples were uniformly ripe and of acceptable color. As shown in column four, ascorbic acid or vitamin C values were also close together, indicating that all the varieties were good food sources of vitamin C. Conversely, total acidity values in column five varied considerably, ranging from a low of 0.435% for Horizon to 0.608% for Bonnie Nematode Resistant. This variety with the highest acidity and one of the lowest pH's had a slightly below average sugar content, which results in a tart flavor. Mountain Pride, on the other hand, with one of the lowest acidity and highest pH and a slightly above average sugar content should be a sweet tasting tomato. The values in the column labeled pH relate to safety for canning, with the lowest values indicating the greatest availability of hydrogen ions (acidity) to combat the growth of spoilage organisms in a canned product. Generally, pH 4.2 is considered a good average for a canning tomato, while tomatoes with pH 4.4 or higher should not be canned TOMATO VARIETY TRIAL, FAIRHOPE, ALABAMA 19851 Average results of the tests by which the varieties were compared are reported in the table. Rankings for each evaluation category are given in parenthesis, with 1 being the most desirable in each case. The first column, soluble solids, indicates the sugar content of the fruit; usually the higher the sugar content, the better the flavor, although the final flavor is determined by the sugar/acid ratio which takes into account total acidity and pH. Tropic and Better Boy ranked the highest of the older varieties and were tied for first place by the new variety Pole Boy 83. Five percent soluble solids is considered good for tomatoes. The second column, labeled Instron, indicates the firmness of the tomato. The rank of unless some food acid such as lemon juice or citric acid is added. In addition to quality factors, a desirable characteristic of tomato plants is the so-called jointless character (J2). Five of the newer varieties and one of the older favorites, FloraDade, have this characteristic. This characteristic of the plant allows the fruit to separate easily from the vine without leaving a short stem attached to the fruit. The yields (pounds per plant) reported are for these varieties grown with ideal cultural practices which include: use of soil testing recommendations for liming and fertilization, a good spray program of fungicides and insecticides, and irrigation as needed. In some aspects the older varieties outperformed the newer ones. Better Boy, Bonnie Nematode Resistant, and Monte Carlo had the highest index rating (lowest total score) and ranked 1, 2, and 3 on yield per plant. The newer varieties Liberty Hybrid, Suncoast, and Castlehy 1035 also had excellent scores. Overall the newer varieties compared favorably to the older ones, especially considering the additional insect and disease resistance from the newer ones.

It can be a mistake, then, to concentrate too much on growing timber and not enough on selling it. When it comes time to convert a timber crop into cash, two selling considerations are paramount: selling when prices are high and qualifying for long-term capital gains treatment of the income. A good way to measure the importance of such advice is to see what difference timber marketing decisions might have on standard measures of investment value-present net worth (PNW) and internal rate of return (IRR). A PNW is a forecast of the immediate value of a prospective investment, stated in number of dollars. It is the sum of all discounted revenues less the sum of discounted costs, hence it is dependent on the interest rate used in discounting. It is a favorite measure of investment value among economists because it neatly accounts for the important financial attributes of an investment. An IRR, instead of giving a dollar value of the investment's immediate worth, denotes an average percentage rate of growth on all of the unre- THE W.A. FLICK covered costs. A bank account in which a $100 deposit today grows to $108 in 1 year has an IRR of 8%. What difference does it make to sell timber at the top versus the bottom of the market? The answer depends on how wide the price gap is between the top and bottom of the timber markets. If timber prices were nearly constant through time, any differences in investment values would be small. As illustrated by the graph, however, timber prices can fluctuate wildly. Since 1976, the absolute range of variation in Alabama sawtimber prices has been $113, from a low of about $84 per thousand board feet (mbf) to a high of $197 per mbf. And some of the peaks and val- sawtimber prices which they would never take when markets are slow and buyers are more selective. An average quality 12-in. log might be worth $160 per mbf as sawtimber in a good market and only $16 per cord, or $48 per mbf, as pulpwood in a depressed market. Landowners who sell timber only occasionally may not be aware of these market changes, but they nevertheless can be devastating to someone selling 25- to 35-year-old timber in a poor market. Finally, timberland owners must know the legal qualifications for capital gains treatment of timber income. If timber is sold properly, that is, in accord with the laws determining capital gains, only 40% of the net capital gain is added to an individual taxpayer's income. Corporate taxpayers benefit too in that they pay tax at a lower rate on capital gains. The effects on a timber investment of changing prices, changing specifications, and capital gains taxation are shown in the table. Those results are derived from an Alabama leys are only four or so months apart. The prices shown are statewide averages-actual prices may vary even more in particular counties depending on local economic characteristics. Prices of pulpwood and intermediate grades also vary, but not as much. Timberland owners must keep in mind that another, more serious variation lurks behind the scenes in timber markets. When markets are booming and the industry wants wood, buyers lower their specifications for AFTER TAX PRESENT NET WORTHS AND INTERNAL RATES OF RETURN FOR LOBLOLLY PINE PLANTATIONS WITH AND WITHOUT CAPITAL GAINS TREATMENT, AND WITH THE COMBINED EFFECTS OF LOW PRICES, PRODUCT DEGRADATION, AND No CAPITAL GAINS TREATMENT Poor-site 50 Discount rate, With' No Combined2 pct. cap. cap. lows gain Dol. 239 -32 -183 -268 3.7% gain Dol. 140 -89 -216 -287 3.1% Dol. -7 -173 -264 -315 1.9% Average-site 60 With No Combined cap. cap. lows gain gain Dol. 789 283 0 -159 6.0% Dol. 578 162 -70 -201 5.3% Dol. 194 -55 -194 -273 3.5% With cap. gain Dol. 1,311 588 182 -48 7.5% High-site 70 No Combined cap. lows gain Dol. 993 404 75 -112 6.7% Dol. 406 72 -116 -224 4.6% 2....... 4 ....... 6 ....... 8 .......

Agricultural Experiment Station study of a loblolly pine plantation in which pine growth, forest management costs, and timber prices were all predicted and combined to create an imaginary pine forest, one which is managed on paper or in a computer, and the results of which are available almost immediately rather than in 30 years. Tree growth was predicted for three sites: poor (site 50), average (site 60), and high (site 70). Land costs were included, and a 30% marginal, federal tax rate was used. All of the financial data were computed on an "after tax" basis, that is, net of federal income taxes. The data are "real" values, meaning they are not inflated by changing prices. On site 70 timberland, if prices are near their high values over the last several years, the IRR of a successful pine plantation is 7.5%. While that might seem low compared to certificates of deposit, mutual funds, and other financial instruments, investors must keep in mind that the 7.5% is a real rate of return, net of inflation and net of federal income taxes. If capital gains treatment is denied because the timber was sold "improperly," the rate of return drops to 6.7%, and if capital gains is denied and timber is sold at the bottom of the market instead of the top, the rate drops further to 4.6%. Similar results can be seen for site 50 and 60 plantations. The research model clearly indicates selling timber carefully and properly is crucial. It demonstrates the importance of consulting a good forester if unsure about the timing of a sale, conditions of local markets, or qualifications for capital gains. The potential of turning financial loss to profit by doing it all correctly is significant.

STRENGTH and D.L. HUFFMAN AND PORK are hard to beat. SProtein BEEF Not only do they appeal to the taste, these red meats are highly nutritious. They provide nutritionally complete proteins that contain the 10 essential amino acids, plus several vitamins and minerals. And, despite claims by critics, neither beef nor pork has excess fat or cholesterol in the lean portions that are traditionally consumed. Proof of the relatively low fat content of lean red meat was established in Alabama Agricultural Experiment Station research. Assorted cuts of beef and pork from Choice carcasses were compared with chicken and fish to determine relative composition of protein, water, fat, minerals, and cholesterol. The meats were closely trimmed of excess fat to produce a high quality, saleable product. "Regular" cuts were representative of the whole, well-trimmed cut, which included small portions of fatty and connective tissue. "Lean" samples were derived only from the lean portions of the same well-trimmed cuts of meat. Similarities in composition of pork, beef, chicken, and catfish are illustrated by data in the table. The differences between regular and lean cuts make it clear that much of the fat and cholesterol are concentrated in the fatty portion of beef and pork. Since this is normally trimmed at the meat market or by individuals when eating, the fat and cholesterol contents pose no health problem. Representative steak cuts were remarkably similar, as shown by the graph. There were only minor differences in the protein, total fat, mineral, and water compositions of lean portions of T-bone, rib, and bottom round cuts. The extra lean ground beef was prepared by separating and grinding of the lean portion from several muscle tissues. This preparation was similar in composition to the other lean cuts. The regular ground beef was prepared in the manner of regular commercial ground beef. The protein contents of all the samples are remarkably similar for the five preparations U T-bone steak Rib steak Bottom round Extra lean Regular ground beef ground beef Lean portions of Choice T-bone, rib, and bottom round beef cuts had about equal amounts of protein, minerals, total fat, and water. in the graph, as well as for five additional common beef cuts analyzed. Lean and regular preparations were analyzed from the 10 cuts, making a total of 20 beef samples analyzed. The protein contents of the 20 samples ranged between 19.2 and 22.7%. Seven major market cuts of the pork carcass were analyzed as lean and regular cuts and the results of the analyses were quite similar to those for beef. The lean cuts of beef and pork contained approximately the same amounts of protein, fat, minerals, and cholesterol. One serving of broiled meat is about 3 oz. (cooked weight). In several trials, lean red meat (upon broiling to medium done) lost about 30% of its weight; thus, 3 oz. is equal to about 4.3 oz. of fresh uncooked meat. The information in the table presents the percentage of total weight made up by each component. The losses during cooking lean meat are due mostly to loss of water; however, cuts containing appreciable amounts of fat lose fat as well as water. One 3-oz. serving of broiled lean beef provides the following percentages of adult man's requirements of essential nutrients: protein, 43; vitamin B12, 75; niacin, 18; thiamin, 24; riboflavin, 15; iron, 14; zinc, 36. In addition, meat is a major source of choline, and lean meat contains the essential polyunsaturated fatty acids. One serving of lean red meat would contain only about 150 calories (5-6% of daily requirement) and 75 to 80 mg of cholesterol (only 25% of the daily cholesterol level recommended by the American Heart Association in a prudent diet). Based on the Auburn findings reported, nutritious red meat can be enjoyed without fear of problems from fat and cholesterol. Strength and Huffman are Professors of Animal and Dairy Sciences.

Weeds pose a serious threat to this increased productivity, because they slow early growth of the watermelons and wrap around vines later, making cultivation difficult. Most of the herbicides currently labeled for use on watermelons have provided erratic control and/or have caused damage to the crop. Tests by Auburn researchers indicate recently labeled Sonolan® and other non-labeled herbicide combinations may provide better control in the future. Of the herbicides currently labeled for use on watermelons, both Alanap® and Prefar® have shown excellent crop tolerance in field tests, but erratic weed control from the former and weed tolerance of the latter limit Evaluation of herbicides for watermelon weed control J.D. NORTON, D.M. COSPER, J.E. BROWN, and M.H. HOLLINGSWORTH ment Station's North Alabama Horticulture Substation in Cullman from 1979 to 1985 screened unlabeled herbicides for effectiveness and crop tolerance on watermelons. Jubilee seed were planted on a Hartselle fine sandy loam soil. Ten herbicide treatments, a hand weeded check, and an unweeded check were evaluated. The plots were 30 X 7.3 ft., with two plants per hill spaced 6 ft. in the row top 20 days after planting. Due to crop dam- age from pre-plant incorporated applications, this method was dropped for the 1984 and 1985 tests. Herbicide treatments and results are shown in tables 1 and 2. Weed and grass control was evaluated 40 their effectiveness. Planavin® and Dacthal® have not provided satisfactory control at labeled rates and have shown some phytoxicity to the plants. Treflan® and Prowl® have not shown adequate crop tolerance on sandy soils. The problem is getting progressively worse as growers run out of weed and grassfree virgin land on which to produce watermelons. Tests at the Alabama Agricultural Experi- Herbicides were applied pre-plant incorporated, preemergence immediately after planting, followed by a light 15-minute sprinkler irrigation, and postemergence over the TABLE 1.

These results indicate the importance of controlling both broadleaf weeds and grasses, table 2. The highest yielding herbicide treatments also produced fruit with the highest percent total soluble solids, table 2. Results from similar tests on cantaloupes gave similar results on weed control, yield, fruit size, and total soluble solids. Data from the test were instrumental in Sonolan gaining clearance for use on watermelons in Alabama. However, registration for use of the product on cucurbits has been withdrawn by the manufacturer.

Farms are being sold because of credit and financial problems. Newspapers report almost daily about the farm situation and bank failures in major agricultural areas. Movies such as "Country" and "Places in the Heart" depict the plight and demise of farms. What is responsible for the situation? Exports of farm products peaked in 1981, declined 15% in 1982, increased some in 1983, and have declined since then. From 1950 to 1981, farm real estate values increased each year with few exceptions. Demand for farm and caused lenders to be more cautious in 1860 ........ 1870 ........ 1880 ........ 1890 ........ 1900........ 1910 ........ 1920........ 1925........ 1930........ 1935........ 1940 ........ 1945........ 1950........ 1955........ 1960 ........ 1965........ 1970 ........ 1975........ 1980........ 1984 ........ 29 52 14 26 12 1 0 3 -1 -4 -6 -5 -18 -15 -15 -12 -15 -3 -3 land was strong by farmers to expand their operations and by non-farmers for investment, speculative, or tax purposes. Since 1981, U.S. farm real estate values have declined, 50% or more in some areas. The decade of the 1970's included several years of substantial inflation in the economy. Real interest rates (nominal rate minus inflation), which averaged 1% to 2% in the 1970's, abruptly rose to relatively high levels when inflation subsided in the early 1980's. Inflation was slowed by stringent control of monetary growth and a worldwide recession that weakened international markets. Interest rates were deregulated and allowed to seek market clearing levels. With high interest rates, foreign capital was attracted to the United States. This resulted in a strong dollar relative to foreign currencies, which led to reduced exports. Farm production costs increased in the 1970's, and high real interest rates in the early 1980's compounded the adverse financial effects. Interest costs became a major expense item with high levels of farm capitalization and operating expenses. Thus, with a decline in exports and increased costs of production, net farm income was squeezed. Farmers faced problems in obtaining credit to finance their operations. Declining real estate values reduced the farmer's equity base their lending practices. An Alabama Agricultural Experiment Station study completed in early 1985 provided information about the financial situation of Alabama farmers. Sixteen percent reported being delinquent in principal or interest payments on real estate loans, 17% on equipment or livestock loans, and 18% on operating loans. The average debt-to-asset ratio reported was 28%, with farmers in the Black Belt Area showing the highest average, 40%. The highest average ratios of debt-to-net income were for farmers in the Gulf Coast and Black Belt. There was some evidence that farms with higher gross sales had somewhat higher delinquency rates. Also, debt-to-asset ratios declined somewhat as age of the farmers increased. When the farmers surveyed were asked if they expected to be farming in the next 5 years, 38% (almost two out of every five) replied "no." The proportion indicating they would not be farming in 5 years was fairly well distributed by farming regions of the State and levels of gross sales. However, 52% of the farmers 60 years old and over indicated they would not be farming in 5 years. Major reasons given for leaving farming were retirement, financial problems, health, and others. If the estimated demise of farms occurs, this could mean that Alabama will have only 35,000 farms by 1990, down from the peak 273,000 in 1935. In 1984, Alabama had 54,000, approximately the same as the number given in the table for 1860. In general, the number of farms in Alabama and the United States has declined since the 1930's. This decline accelerated after World War II as capital in the form of machinery and equipment, fertilizer, chemicals, and other inputs increasingly was substituted for labor. Total capital investments in farms and annual operating expense requirements increased substantially as farms be- Source: Various Censuses of Agriculture. came larger and more capital intensive. Many people left the farm to find employment in nonfarm industries and firms. The decline in number of farms was also associated with increases in size. From 1950 to 1985, the average size of Alabama farms doubled while the number of farms and farmers declined from 200,000 to 54,000. The release of people from agriculture, in a large measure, made possible the growth of manufacturing, trade, and service components of our economy. The decline in farm and farmer numbers that started about 50 years ago apparently is being accelerated by the financial situation today. Will farmers become an endangered species? Implications derived from research are that middle size farms may be the ones that will decline most. Generally, larger farms are somewhat more efficient and are able to take advantage of economies of scale in their operations. At the other extreme are small farmers who depend on off-farm work for most of their income, and this allows them to continue farming even under unfavorable economic conditions. Agribusiness firms face substantial adjustments in their operations, product sales, and services in order to survive. The concept of the farm as strictly a family enterprise is increasingly outdated. Modern farmers are marketers and financial managers who are breaking old ties with local firms. As a result, an increased number of small towns will likely wither away. Thus, the decline in farm and farmer numbers will have far-reaching effects.
