Nitrogen is the most critical fertility element for most crops but is the only element that is not released to the soil from the parent minerals. Nature transfers nitrogen from the atmosphere to the soil through rainfall and the symbiotic relationship of legumes with rhizobium bacteria. Each family of legumes requires a specific race of rhizobium which is unlikely to occur naturally in significant numbers within the field where the legume is to be planted. Maximum nitrogen fixation is best achieved when the correct rhizobium inoculant is applied to the seed. Legumes planted as seed mixes should be inoculated at a heavy rate to compensate for the “dilution” of inoculant material on non legume seed.
