Sorghum is widely adapted and works well as a ground cover, weed suppressor and soil builder. Sorghum sudan is an excellent nutrient scavenger – catch crop, highest producer of biomass of the summer cover crops.
Mowing sorghum sudan when it reaches 3 to 4 feet tall will increase the root mass five to eight times compared to unmowed sorghum sudans. It winter kills easily and, because it’s a succulent, breaks down well through the winter.
Seed 25-60 lbs/A at a depth of 3/4 to 1 1/4 inches. Plant as a summer cover crop when the soil temperatures are at least 60°F. Sowing at higher rates, 70 lbs or more, makes an excellent smother crop for fields with weed problems.
