Agricultural cornmeal is a good nitrogen source because it encourages the friendly fungal species Trichoderma to proliferate. This fungus feeds on the plant pathogens Sclerotinia minor (a blight characterized by the appearance of cotton-like growths on plant stems at the ground line followed by sudden plant death); Sclerotium rolfsii (Southern blight); and Rhizoctonia spp. (this is a disease that attacksstems, stolons and tubers of many plants, especially potatoes). Research conducted at Texas A&M University on peanut diseases confirms the usefulness of agricultural cornmeal.
