Organic Corn - 1995 Drought

Organic Conventional

Better infiltration, retention, and delivery to plants helps avoid

drought damage

• Higher corn and soybean yields in drought years

• Increased soil C and N

• Higher water infiltration

• Higher water holding cap.

• Higher microbial activity

• Extends plant root systems

• Produces erosion-resistant, carbon enriched soil

• Provides mechanisms for soil biological carbon fixation

• Slows decay of organic matter
