Impact of Disease Suppressive Composts on Organic Vegetable Quality Composition and Yield
Anusuya Rangarajan, Cornell University

The goal of this research was to initiate studies on compost effects on severity of common soil borne diseases and to characterize changes plant growth due to improved nutrient availability and soil microbial activity with compost application in organic production systems.
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
