摘要：

Highly weathered soils of the Southeastern USA are poorly structured and may present special problems under continuous no-tillage production. Soil physical properties were examined in a long-term tillage experiment starting in its 10th year to determine if there were differences due to tillage. Fall/spring tillage treatments consisted of moldboard plow/moldboard plow (CT), moldboard plow/no-tillage (MT), and no-tillage/no-tillage (NT). Cone index measurements in NT exceeded 4 MPa at a depth of 0. 10 to 0. 20 m, indicating the presence of a compacted zone. We conclude that during short-term summer rainfall events, infiltration in conventionally tilled soil is controlled by surface crusting.
