Use of Urea for Crop Production in Kentucky

Current trends indicate that urea will become the major source of solid and liquid N fertilizer in the future. Although urea has several advantages over other N fertilizers, especially in manufacturing, transporting, and marketing, there are some potential agronomic problems that farmers should keep in mind when using urea

Returning PIK Land to Grain Production

With the end of the 1983 PIK program, much of the acreage that was in the program will be returned to grain production. Farmers who planted cover crops on their PIK fields in 1983 and who plan to return them to grain production in 1984 will be faced with deciding whether to use no-tillage or conventional tillage. The cover crops will provide mulch for no-tillage crops which may be an asset but can contribute to problems as well. Also, weed problems may be worse on PIK land and more difficult to control with no-tillage than with conventional tillage. The decision on what tillage system to use should basis made on the basis of site-specific conditions of each field. Some thoughts to consider are discussed below

Energy Conservation in Corn Production

On-farm production of food and fiber uses about 3% of the annual U.S. energy consumption. About one-third of this energy is directly from fossil fuels used in farm tractors and trucks and for crop drying, while about one-fourth is used in manufacturing and transporting fertilizers. Tillage and N fertilizers are the two largest uses of energy in non-irrigated product ion of crops which are not dried artificially. Thus, the greatest effects of energy conservation can be achieved in these two areas
