Fertilization Practices For Double Cropping Systems, John H. Grove

Agronomy Notes

Double cropping has become an important practice in the state of Kentucky. While the wheat-soybean grain intensive production system is the most widely used on an acreage basis (approx. 3/4 million acres per year) several other systems are being adopted by Kentucky growers. Most of these involve some silage production for beef and/or dairy cattle. The fall seeded small grain (wheat, barley, triticale) is harvested at an immature stage of growth and ensiled and a subsequent crop for silage (corn, grain sorghum) or grain (soybean, grain sorghum) is planted. The use of reduced and no-tillage management will speed up planting …

An Estimate Of The Soil Fertility Status Of Graves And Todd Counties In Kentucky, Kenneth L. Wells, D. E. Peaslee, Marvin Davidson, William Green

Agronomy Notes

Some concern has developed during recent years that fertilizer is being used by farmers on fields with residual levels of P and K high enough that such use is not justified as a means of increasing crop yields. This has been due to increased "average" soil test values for samples routinely submitted to college soil test laboratories.

For this reason, studies were conducted in Graves and Todd Counties in Kentucky during the period September, 1978 to September, 1980, to determine if soil samples routinely submitted to college test laboratories do or do not accurately reflect the average soil fertility status …
