Nitro Radish

Daikon radish is a brassica with a deep tap root that penetrates subsoil, improves tilth, and scavenges and bio-accumulates nitrogen, calcium, sulfur, and magnesium from lower soil levels, bringing nutrients up to regions where they are usable by other crops. Radishes’ leafy canopy suppresses weeds; they also secrete chemicals that help inhibit weed germination, as well as chemicals that suppress nematodes. For this reason, many brassicas are known as “bio-fumigants.”
