End Date: Aug 14, 2012
A composite brassicaceous seed meal in concert with use of a disease tolerant apple rootstock will be evaluated as an alternative to soil fumigation for control of apple replant disease in field trials. The impact of seed meal particle size on generation of biologically active chemistries (allyl-isothiocyanate) from Brassica juncea seed meal soil amendment, and composition of the resident soil microbial community contributing to disease suppression. The effect of different brassicaceae seed meals or composite seed meal amendments on composition and activity of resident soil fauna communities involved in N mineralization will be determined. The use of a composite seed meal to decrease rates nitrification and thus minimize N loss resulting from leaching will be assessed. Documents Reimbursable with CSREES. Log 35377.
