Cover Crops and Biological Farming

In this excerpt from “Advancing Biological Farming,” Gary Zimmer discusses the critical importance of cover crops in a biological farming system.

Vetch Cover Crops Benefit Organic Zucchini Growth

Vetch Cover Crops Benefit Organic Zucchini Growth

“Our results showed that zucchini yield was influenced positively by the vetch residue management strategy, although the response was significantly different between years,” the scientists said. “The vetch cover crop increased marketable zucchini yield in the first year by 46.6 percent compared with the fallow treatment, indicating that this fertility-building crop could reduce off-farm nitrogen (N) fertilizer input for subsequent crops.

Cover Crops for Pest Management
