RT Journal Article SR Electronic T1 Tillage effects on soil properties, diseases, cyst nematodes, and soybean yields JF Journal of Soil and Water Conservation FD Soil and Water Conservation Society SP 374 OP 376 VO 38 IS 4 A1 Tyler, D. D. A1 Overton, J. R. A1 Chambers, A. Y. YR 1983 UL http://www.jswconline.org/content/38/4/374.abstract AB Five conventional tillage methods were compared with a no-till system for soybean production. Changes in soil organic matter and soil penetrometer resistance were evaluated. Tillage effects on diseases and soybean cyst nematodes were also observed and measured. Yields generally did not vary significantly among tillage treatments.
