Soil Conservation Provisions Of The 1985 Farm Bill, Monroe Rasnake, Lloyd W. Murdock, Craig Infanger Dec 1986

Soil Conservation Provisions Of The 1985 Farm Bill, Monroe Rasnake, Lloyd W. Murdock, Craig Infanger

Soil Science News and Views

The 1985 Farm Bill which was signed into law on December 23, 1985, contains 3 provisions relating to land use which will have a large impact on Kentucky farmers. The purpose of these provisions is to reduce cropland acreage on highly erodible lands and on wetlands. A description of them follows.

Economics Of Legume Cover Crops, Wilbur Frye Sep 1986

Economics Of Legume Cover Crops, Wilbur Frye

Soil Science News and Views

We have compared hairy vetch, big flower vetch, rye, and corn residue as winter cover treatments in no-tillage corn production since 1977. One of the objectives of this research is to determine the economic feasibility of using a legume cover crop to supply a portion of the nitrogen needs of a corn crop. Results reported here are based on corn yields obtained during 1977 through 1981 at Lexington and 1980 through 1985 at Princeton.

Effect Of Soil Water Stress And Irrigation On Growth, Yield And Quality Of Burley Tobacco, Ronald E. Phillips, J. E. Leggett Jul 1986

Effect Of Soil Water Stress And Irrigation On Growth, Yield And Quality Of Burley Tobacco, Ronald E. Phillips, J. E. Leggett

Soil Science News and Views

An experiment was conducted for a period of three years, 1982, 1983 and 1984, in order to evaluate the effects of soil water stress and irrigation on growth, yield and quality of burley tobacco at Spindletop Farm, Lexington. The variety KY 21 was grown all three years. Three treatments were used in the experiment: (1) check, rainfall only, not irrigated, (2) well watered, rainfall plus supplemental irrigation, and (3) water stressed beginning 50 days after transplanting. The soil of treatment 3 was covered with black plastic to prevent rainfall from entering the soil.

Soil Erosion With Different Tillage And Cropping Systems, Monroe Rasnake, Wilbur Frye, David C. Ditsch, Robert L. Blevins Jun 1986

Soil Erosion With Different Tillage And Cropping Systems, Monroe Rasnake, Wilbur Frye, David C. Ditsch, Robert L. Blevins

Soil Science News and Views

Corn and soybeans are produced on approximately three million acres of Kentucky farmland each year. L 1ttle soil loss occurs when these crops are grown on nearly level or gently sloping land. However, much of the grain production is on sloping land that is cultivated every year and often excessive soil erosion occurs. If a field is allowed to erode excessively for several years, the soil usually becomes less productive. Soil removed in runoff may pollute lakes and streams or cover highly productive soil with low quality sediments.

Ridge-Tillage: Advantages And Disadvantages, David C. Ditsch Apr 1986

Ridge-Tillage: Advantages And Disadvantages, David C. Ditsch

Soil Science News and Views

Ridge-Till is a crop production system that has become increasingly popular with grain producers in some areas of the mid-west. This unique tillage system may provide some Kentucky farmers with an alternative method of planting. Limited information on the adaptability of ridge-till on Kentucky soils and climatic conditions make it important that growers investigate the system thoroughly to determine how it would fit into their operation before deciding to change. Ridge-till involves planting on elevated rows that remain undisturbed after establishment. One or more cultivations are then made during the early part of each growing season to improve weed control, …

Timing N-P-K Fertilizer To Burley Tobacco, J. L. Sims Mar 1986

Timing N-P-K Fertilizer To Burley Tobacco, J. L. Sims

Soil Science News and Views

Recent changes in the Federal tobacco program (causing reduced income to growers} coupled with high fertilizer and other production costs have stimulated interest in fertilization practices that increase efficiency of tobacco production. Practices that increase yields and/or quality of cured leaf without increasing production costs should result in increased profit. Research conducted by Agronomists at the University of Kentucky indicates increased yield is possible through proper timing of fertilizer applications, split applications, and in some cases by banding applications.

Effect Of Soil Mineral Variability On Soil Use And Management, Anastasios D. Karathanasis Feb 1986

Effect Of Soil Mineral Variability On Soil Use And Management, Anastasios D. Karathanasis

Soil Science News and Views

Soil mineralogical variability arises from two factors. The mineralogical composition of the parent material and the degree to which the original composition has been modified by external soil forming factors and internal soil building processes during the course of weathering. Different stages of soil weathering are represented by different mineralogical compositions and therefore a different combination of physical and chemical properties. Some soil scientists have divided these weathering stages into fresh, juvenile, virile, senile, and lateritic. The ability of soil to provide nutrients to plants reaches a maximum at the beginning of the virile stage and then declines rapidly with …

Cutting Production Costs In 1986, Kenneth L. Wells, John H. Grove Jan 1986

Cutting Production Costs In 1986, Kenneth L. Wells, John H. Grove

Soil Science News and Views

With the stressful economic situation that continues to face Kentucky farmers in 1986, the College of Agriculture is continually asked, "What are some of the things which can be done to ease the cost-price squeeze?" In response to this question, the following suggestions for improved, more cost efficient soil and crop production management are offered: These management techniques to get the highest possible yields without added costs are sometimes overlooked although they can offer increased yield potential at no added cost.
