Mustard seed - non-gmo

This is a certified organic mustard seed. Brassica juncea or Sinapis alba Annual broadleaf. Up to 5'. Moderately frost resistant. Produces large amounts of biomass containing high levels of glucosinates that break down into compounds toxic to nematodes and soil-borne disease-causing organisms. Does not tolerate drought. Allow the plants to grow fairly large to maximize the glucosinate concentration, and then chop fine and incorporate into the soil. Allow 2 weeks for the plant to break down before planting a new crop. Plant 1½" deep in a firm moist seed bed at 15–25#/acre, 1–2#/1000 sq ft. As cover crop: Best as a fall-planted cover crop to retain nutrients, suppress weeds and improve water penetration. Plant in the spring as a green manure and to suppress nematodes and diseases.
