Impact of Disease Suppressive Composts on Organic Vegetable Quality, Composition and Yield

Project Objectives

-Analyze several animal manure-based, organic-approved compost products for suppression of important soil-borne pathogens of vegetable crops in the Northeast -Determine applicability of a farmer-based test kit for assessment of compost maturity to predict suppressiveness -Evaluate compost effects on plant stand and crop composition -Determine changes in microbial activity, disease suppressiveness and soil nitrate nitrogen of organically managed soils after addition of a compost
