Organic Farming Research Network

OEFFA and the Ohio State University (OSU), with support from the U.S. Department of Agriculture Organic Agriculture Research and Extension Initiative, are working to address gaps in research on soil management in organic systems.

Soil balancing using the Basic Cation Saturation Ratio (BCSR) approach relies on adding limestone and/or gypsum and taking other steps to alter soil chemistry. The BCSR approach may, in turn, enhance soil life and tilth, improve weed and insect control, and increase crop yield and quality. However, the effects of soil balancing, particularly in real-world farm settings, have not been systematically or scientifically researched.
OEFFA, researchers at the Ohio State University, farmers, and other agricultural experts are collaborating to learn more about soil balancing to help farmers use this method more effectively and gain a greater understanding of how soil balancing affects weeds, pests, and crops.

As part of this project, OEFFA and OSU are working to establish a statewide network of certified organic farms willing to host and participate in on-farm research on soil balancing and other topics.
