Abstract
The soilborne pathogen Fusarium solani f. sp. glycines causes sudden death syndrome (SDS) of soybean. Previous research indicated that soil compaction related directly to disease foliar symptoms. Therefore, we hypothesized that decreasing soil compaction would increase soil porosity and provide a more aerated root zone that would hinder root infection by the fungus and decrease SDS foliar symptom severity. Two experimental areas (110 by 120 m) were established to evaluate the relationship between soil variables and SDS. Across the experimental area, strips (9.14 m wide) were subsoiled perpendicular to soybean rows to a depth of 40 to 45 cm, which alternated with strips that were not tilled. In both 1999 and 2000, subsoiling dramatically reduced foliar symptoms of SDS. Compared with no-till plots, subsoiled plots had lower soil bulk density, greater soil porosity, and less soil moisture. In areas where SDS occurs and soil compaction exists, the use of subsoiling can be used to reduce severity of foliar symptoms of SDS.
