After 22 years of farming, my farm’s soil is markedly more fertile and productive. It has been a wonderful journey learning what works and how to continue to improve long-term productivity while harvesting bountiful crops.
There are several methods that deserve credit for this increase in soil quality: the use of compost, the use of a balanced mineral fertilizer and a serious commitment to cover cropping.
For this article I want to focus on the growing of cover crops and green manures. When I became the farm manager at Potomac Vegetable Farms – West in 1992, I sought advice on how to transition the farm into organic production.
The land had been growing mostly sweet corn, pumpkins and green beans with commercial chemical fertilizers and herbicides. The soil was biologically inactive and nutrients were missing. I can clearly remember the words from a fertility consultant, “I can sell you something in a bag, and I can sell you something in a bucket, but what you really need to do is to make compost and grow cover crops.” And thus began my journey into both compost-making and cover cropping.
Why take on both of those jobs rather than just one? Well, they go hand in hand, each leveraging the benefits of the other to move a soil more quickly toward health and resilience.
