The Effect Of Three Tillage Systems On Bulk Density And Porosity Of A Pembroke And A Beasley Soil After Three Years, Kenneth L. Wells, John H. Grove

Agronomy Notes

Many grain producers in Kentucky use a 3 crop in 2 year rotation of corn followed by small grain-soybeans, and commonly no-till the soybeans and corn in order to intensively use sloping land for continuous grain production. Because of the intensity of machinery traffic in this system, growers are concerned that continuous no-till management may cause compaction, and that such fields may need occasional primary tillage. In order to obtain' information regarding things situation, we conducted a test for 3 years on the farm of' Philip Lyvers, in Marion County, Kentucky, in a field which was being used in a …

1987 Update Of Agronomic Performance Of Tall Fescue Varieties, Paul B. Burrus Ii, Garry D. Lacefield, J. Kenneth Evans

Agronomy Notes

Tall fescue (Festuca arundinacea, Schreb.) is a well adapted, widely used pasture species occupying approximately 5.5 million acres in Kentucky and 35 million acres in the south central United States.

Commercial tall fescue varieties have been developed from plant materials of either northern European or Mediterranean origin. Varieties developed at the University of Kentucky -- Kentucky 31, Kenmont, Kenwell, Kenhy, and Johnstone -- trace to plant materials of northern European origin. The Kentucky varieties have later maturity dates and have greater resistance to certain foliar diseases during summer than varieties that are of Mediterranean origin (i.e., Alta, Fawn, Goar, and …

Effect Of Fertilizer Rates And Placement Practices On Yield Of Burley Tobacco, Kenneth L. Wells, G. D. Cantrill, J. L. Sims

Agronomy Notes

Management of fertilizer practices in production of burley tobacco is very important in control of manganese (Mn) toxicity of the crop. In addition to the use of agricultural limestone, the use of fertilizers in the appropriate amounts, the appropriate kinds, and in the appropriate manner can strongly influence acidity in the rooting zone during the growth of burley. Studies of these effects have made up a major thrust of the University of Kentucky's research programs on fertility of burley, and have largely been conducted by J.L. Sims and his students during the past 15 years.

Adjusting Soil Ph On Heavy Textured Soils Of The Eden Hills, Kenneth L. Wells, R. M. Jones

Agronomy Notes

The Eden Hills Area (also known as The Hills of the Bluegrass) of Kentucky lies adjacent to the Inner Bluegrass Area in a crescent shape within which a large area of several counties occur. Carroll, Owen, Grant, Gallatin, Pendleton, and Robertson Counties occur almost entirely within this physiographic region and several other counties have sizable acreages within it. Soils of the area have formed largely on Ordovician aged calcareous siltstones of the Garrard Formation and interbedded calcareous shales, thin limestones, and siltstones of the Eden Formation. Soils developed from these formations occur on strongly sloping to steep landscapes and have …
