Mustard cover crops help significantly control pests because they contain a higher amount glucosinolate than other brassicas, and this chemical compound wards-of harmful insects, especially when the plant cells are ruptured when the plants are mowed down. Known for their rapid fall growth, Mustards makes a great weed suppressor because weeds don’t have a chance to take of the soil and grow. Mustard’s roots burrow deeper than other scavengers for nutrients, which also help ward-off soilborne pathogens. Expect about eighty percent soil coverage.
