Basic Steps In Laying Out A Land Tract To Optimize Forage Production And Intensive Grazing Management, Harold B. Rice, Kenneth L. Wells
Basic Steps In Laying Out A Land Tract To Optimize Forage Production And Intensive Grazing Management, Harold B. Rice, Kenneth L. Wells
Soil Science News and Views
Of the four major components of production ... land, labor, capital, and management ... land (soil) is the one which is the most basic. This ls because soil characteristics are largely "fixed" and determine, along with the climatic regime, the crop species which will perform best in a given field. For this reason. It Is basic in planning a cropping system to know root-zone physical and chemical characteristics of soils which occur on the tract being planned. With such information, crops can be matched to sell productivity to "make land as least limiting as possible." A good soils map is …
Estimating Potential Ground And Surface Water Pollution From Land Application Of Poultry Litter, J. T. Gilmour, D. C. Wolf, P. M. Gale
Estimating Potential Ground And Surface Water Pollution From Land Application Of Poultry Litter, J. T. Gilmour, D. C. Wolf, P. M. Gale
Technical Reports
In 1985, more than 750 million broiler chickens were produced in Arkansas. During the same year over 15 million laying chickens produced 3.6 million eggs. The waste products of these agricultural production systems, poultry litter and manure, were about 1 million metric tons. As a result of land application of these wastes, about 5,000 metric tons of annnonium N and 12,000 metric tons of mineralized nitrogen were applied to Arkansas pastures in 1985. Manures contributed about 2-3 percent of the total. The objective of this research was to quantify major components of the nitrogen cycle which influence the ground and …

Control Measures For Manganese Toxicity Of Burley At Transplating Time, Kenneth L. Wells, J. L. Sims
Control Measures For Manganese Toxicity Of Burley At Transplating Time, Kenneth L. Wells, J. L. Sims
Soil Science News and Views
Manganese (Mn) toxicity of burley tobacco is viewed by tobacco specialists in Kentucky as the greatest single factor which reduces yields. Estimates are that this problem adds 30 to 50 million dollars to the cost of burley production because of the greater acreage (and all associated costs) required by growers to produce their allotment. And, even though the cause and cure of Mn toxicity has been known for about 50 years, many growers are caught each year at transplanting time with no knowledge as to whether Mn toxicity may be a problem in their fields. The solution to Mn toxicity …
Is Row Fertilizer Necessary For No-Till?, Lloyd W. Murdock, William O. Thom
Is Row Fertilizer Necessary For No-Till?, Lloyd W. Murdock, William O. Thom
Soil Science News and Views
Row fertilizer is an old practice which has been in and out of favor over the years. The use of row fertilizer and its benefits vary with the conditions. The efficiency of applied fertilizer is greatly increased by putting it beside the row and is very helpful on soils with a low soil test. For soils testing medium or high, a sufficient amount of nutrients exist in the soil so that additional fertilizer applied in the row will not increase yields. Regardless of soil test. row fertilizer will usually increase the vigor and early growth of a crop. Most of …
Tb126: Vertical Trends In The Chemistry Of Forest Soil Microcosms Following Experimental Acidification, Ivan J. Fernandez
Tb126: Vertical Trends In The Chemistry Of Forest Soil Microcosms Following Experimental Acidification, Ivan J. Fernandez
Technical Bulletins
A soil microcosm experiment was conducted (a) to compare dilute H2SO4, NH4NO3 fertilizer, and prilled S as possible experimental soil-acidifying treatments and (b) to observe soil chemical response to simulated throughfall and acidifying treatments. Simulated throughfall had a significant effect on soil chemistry, resulting in increased exchangeable bases and pH in the mineral soil horizons but little effect on the O horizon. Of the acidification treatments only simulated acid rain had significant effects on soil chemistry when compared to the control and the dry treatments. This reflected the relatively slow dissolution rate of the dry treatments coupled with the short …

Basic Fertilizer Facts, Monroe Rasnake
Soil Science News and Views
The "foods" used by green plants for growth and life functions are referred to as nutrients or fertilizer elements. There are 16 nutrients required for plant growth and development (See Table l). Although carbon, hydrogen, and oxygen are found in plants in the greatest quantities. they are obtained by plants from air (carbon dioxide) and water rather than from fertilizers or the soil. Of the nutrients provided by the soil or from fertilizers. those required in large amounts are called PRIMARY nutrients. Those required in smaller amounts are called SECONDARY nutrients, while those needed in very small amounts are called …
Marketing Quality Alfalfa Hay, Garry D. Lacefield
Marketing Quality Alfalfa Hay, Garry D. Lacefield
Kentucky Alfalfa and Stored Forage Conference
Alfalfa hay is a potentially marketable-profitable product if--if quality is satisfactory to meet buyer's needs, if it is packaged such that it meets buyer's feeding program and can be transported efficiently, if in sufficient quantity, if storage site is accessible by truck or trailer, and if it is competitively priced. Meeting these minimum criteria only means the hay is potentially marketable; only after it has been sold does it become potentially profitable.
Feeding Alfalfa To South Carolina Dairy Herds, Fred E. Pardue, Terry Sudduth
Feeding Alfalfa To South Carolina Dairy Herds, Fred E. Pardue, Terry Sudduth
Kentucky Alfalfa and Stored Forage Conference
The nutritional value of alfalfa hay is important if it is to be used competitively with other feedstuffs in rations being fed to South Carolina Dairy Herds. Excellent quality hay has high nutrient concentration, digestibility and intake. The appearance of good physical characteristics of alfalfa hay as well as other hays and forages along with the knowledge of harvest dates, stages of maturity, and other conditions are not enough and can be deceiving. Therefore, forage testing is crucial and very important.
Marketing Kentucky Hay — An Update, J. Kenneth Evans
Marketing Kentucky Hay — An Update, J. Kenneth Evans
Kentucky Alfalfa and Stored Forage Conference
Based on soil capabilities, Kentucky could grow 2-million acres of alfalfa while increasing the acreage of corn and soybeans. Even more than 2-million acres could be grown if Kentucky grown alfalfa should show market demands making it economically competitive with corn and soybeans. Marketing is the key to developing demand which could make hay a $1-billion Kentucky crop.
Many of you have heard or read my comments on marketing hay. In this presentation, I will present a brief review of what I have previously said and then bring you up to date on hay marketing activities since the alfalfa conference …
Evaluating Alfalfa Grazing — Dollars And Cents, Robert N. Barnes
Evaluating Alfalfa Grazing — Dollars And Cents, Robert N. Barnes
Kentucky Alfalfa and Stored Forage Conference
Returns on many Kentucky farms are declining due to reduced tobacco and feedgrain income. This fact, coupled with traditionally low (or negative) returns from typical cow/calf beef enterprises, has been associated with interest in alternative crop and livestock production systems. Alfalfa produced as a cash crop is increasing and many farmers are realizing substantial returns. In the Central Kentucky Area, many farmers have been stimulated to produce alfalfa since demand for high quality hay by horse farms has been strong. As interest in alfalfa is renewed, other farms have begun to introduce intensive or controlled grazing techniques in order to …

- Minimize the occurrence of bloat where possible.
Comparison Of Electrical Moisture Meters For Baled Alfalfa Hay, W. H. Henson Jr., G. M. Turner, Michael Collins, O. J. Yeoman
Comparison Of Electrical Moisture Meters For Baled Alfalfa Hay, W. H. Henson Jr., G. M. Turner, Michael Collins, O. J. Yeoman
Kentucky Alfalfa and Stored Forage Conference
A primary concern in producing quality alfalfa hay is moisture measurement. Some precision in moisture measurement is required since hay can be too wet, leading to dry matter and quality loss through mold; it can be too dry, leading to shatter loss during baling, handling and storage.
Moisture measurement in hay can take many forms. One form of subjective (personal judgment) evaluation is brittleness of leaves and stems in the windrow or bale. Typical objective methods consist of electric meters with calibration curves and oven drying.
Advances In Alfalfa Weed Control, James R. Martin
Advances In Alfalfa Weed Control, James R. Martin
Kentucky Alfalfa and Stored Forage Conference
The most significant advances in weed control in alfalfa have originated from developments in herbicide technology, This method of weed control began over 20 years ago when such herbicides as EPTC and 2,4-DB were being used by alfalfa farmers. Since then, more than twelve herbicides have been added to the list of products recommended for weed control in alfalfa. (For specific recommendations, see Extension publication "Chemical Control of Weeds in Kentucky Farm Crops", AGR-6).
Influence Of Potato Leafhopper On Alfalfa Yield And Quality, C. M. Christensen
Influence Of Potato Leafhopper On Alfalfa Yield And Quality, C. M. Christensen
Kentucky Alfalfa and Stored Forage Conference
The potato leafhopper has the distinction of being one of the native insects that can have a very major impact on the production characteristics of alfalfa. This insect is very definitely the second most important pest of this crop, with the alfalfa weevil, an imported insect, holding the distinction of being the most damaging. These tiny insects (full grown potato leafhoppers are 1/8 inch long) have a very definite impact on alfalfa but their damage is very insidious and hard to recognize.
Quality Seed Production And Use, Garry D. Lacefield
Quality Seed Production And Use, Garry D. Lacefield
Kentucky Alfalfa and Stored Forage Conference
Quality seed is an important consideration and investment in an efficient alfalfa program. Farmers who depend on alfalfa need to be certain that the seed they purchase is of high quality. High quality seed means it must be free of noxious weeds, have a purity of 99.5 percent, a germination of approximately 90 percent or higher and be seed that is true to the variety stated.
