Soil in Organic Systems
• Higher corn and soybean
yields in drought years
• Increased soil C and N
• Higher water infiltration
• Higher water holding cap.
• Higher microbial activity

Mycorrhizal Fungi
• Extends plant root
systems
• Produces erosionresistant, carbon
enriched soil
• Provides mechanisms
for soil biological
carbon fixation
• Slows decay of organic
matter
