Abstract

Planting corn and soybeans in sod (commonly referred to as "no-tillage" planting) is increasing in parts of Kentucky, and interest in this practice in other parts of the state is growing.

One question is often asked: 'What is the best method of liming and fertilizing no-tillage corn and soybeans?"

Since no-tillage planting is a comparatively new practice, only a limited amount of research on methods of fertilization has been done. However, research designed to find out how well plants can recover phosphorus and potassium applied on the surface of the soil will be started by the Department of Agronomy at the University of Kentucky in 1968. This research will determine the comparative effectiveness of surface applications of these fertilizer materials vs. incorporation in the upper 6 inches of the soil.
