Abstract

Abstract

In recent years double-crop winter wheat (Triticum aestivum L.) and soybeans [Glycine max (L.) Merr.] have become quite common in the southeastern USA. To minimize the time between harvest of the winter crop and planting of soybeans, many farmers have adopted reduced or no-tillage systems. A 2-yr experiment was conducted on an Ultisol in Georgia to assess the influence of these tillage practices on soil physical properties. Spring tillage treatments were no-tillage, disking, and moldboard plow plus disking. Fall tillage prior to planting wheat was with a disk. Bulk density and mechanical impedance measurements indicated a compacted layer in the disked and notillage treatments at a depth of 0.15 to 0.25 m. This was attributed, in part, to the fall disking, and it persisted through the winter and into the next growing season.
