Seed treatments offer protection from fungi, insects, and nematodes to germinating seeds and developing seedlings. All legumes require the appropriate rhizobium bacteria in the soil in order for nitrogen fixation to occur. Inoculating the seed with an inoculum can insure the crop can take advantage of this nitrogen fixation.
