Soil Health Evaluation on Organic Farms

This study looks at cover crops and compost effects on soil health in organic vegetables. C MacNeil crm6@cornell.edu 585-394-3977

Fertility sources for Organically-Grown Tomatoes

Berseem clover, NC 5-3-4 fertilizer, peanut meal, fish meal, and chopped vetch plus liquid fish 3-3-.3 were compated for yields and plant growth. Marketable yields did not show statistical differences between treatments. M McGrath mtm3@cornell.edu 631-727-3595

Organic Farm Nutrient Budgets

Research and databases are being developed to help farmers calculate nutrient flows leaving their farms in vegetable and grain crops. This helps plan fertility inputs to avoid costly surpluses. L Drinkwater led24@cornell.edu 607-255-9408

Organic Fertility Recommendations

Fertility recommendations are needed for organic farms, but are not well established. This is a long-term study looking at different compost types and application rates and the effect on crop yield. T Bjorkman tnb1@cornell.edu 315-787-2216
