Vertical Trenching of Cellulose Waste to Hinder Hardpan Reconsolidation. Written for Presentation at the 1996 ASAE Annual International Meeting, Phoenix, AZ. Paper No. 961044

摘要

Trenches placed midway between rows were filled with a mixture of soil, cellulose material, and poultry litter. Soybeans and grain sorghum were grown in rows adjacent to the trenched areas for multiple years. Results showed that a trenching effect, with or without the presence of cellulose, significantly increased plant yields, particularly in dry years. Cone index measurements taken three years after the trenches were created showed no sign of hardpan consolidation from natural forces.
