Organic Farming & Soil

Center for Food Safety

Modern organic farming combines tradition and innovation.  Recognizing the value of reduced tillage for soil health, a technique known as “organic no-till” is becoming more popular.  Instead of plowing in the cover crop in the spring, a new device known as a “roller-crimper” is used to crush and kill it.  Not only is erosion reduced and soil tilth maintained, but the killed cover crop forms a mat that suppresses weeds in the main crop, which is seeded through the mat.

Mainstream farmers are slowly learning from organic practitioners, though they have a long way to come.  For instance, the conservation tillage movement was motivated by the core principle of organic agriculture – improving soil quality as the key to sustainable food production.  More recently, mainstream growers have become more interested in planting cover crops, which has long been the province of organic farmers.  Unfortunately, most mainstream farmers continue to make liberal use of often toxic herbicides, greatly diminishing the benefits provided by these techniques.
