Organic Weed Control Case Studies

Below are various case studies that show how individual farms approached ecological weed management techniques.

Case Studies

The Nordell Summer Fallow System

Anne & Eric Nordell of Trout Run, Pennsylvania, nearly eliminated weeding needs by using a rotation of vegetable crops, followed by a year of summer fallow with spring and fall cover crops. The intensive summer tillage prevented annuals from seeding and also helped wear down perennial weeds. The negative effects of intense tillage were offset by incorporating the spring and fall cover crops. This method resulted in a bare minimum of weeding needs which improved over the years.
