Former cropland replanted with a variety of grasses and broadleaf plants.

Replanting Cropland Back to Grassland

Planting cropland back to grassland takes some planning regarding previous herbicide use, soil fertility and seed bed preparation. The first step is to identify what resources are currently available to help you reach your objectives and what problems may need to be addressed.

Left: Soil from long-term no-till field, exhibiting good soil aggregation through clumping and smaller pieces of soil. Right: Soil from conventionally managed field that included tillage and crop residue removal. Notice the soil is lighter brown, indicating lower organic matter, and the pieces of soil are in larger chunks with no visible indication of clumping or structure.

Organic Agronomy Starting to Impact

For decades scientists have known that a handful of soil contained more micro-biological organisms than the number of humans on earth. Science is just beginning to discover these organisms and learn about their functions and contribution to their soil ecosystem.
