Soil Health (Tillage, Residue Management., Cover Crops), High Yield
Two rows of cover crops, each spaced 7.5 in. apart, were drilled between 30 in. wide soybean rows during flowering (R1/R2). A drill interseeder mounted on a 3 point hitch capable of seeding 5 soybean inter-row spacings at a time was used to perform the operation. Plots were 30-40 ft long and were harvested with a plot combine on Oct. 19. Biomass sampling was performed in late-Nov.
There was no significant yield difference with the red clover cover crop interseeded at flowering. However there was significant difference in cover crop biomass among landscape positions.
