SOLD OUT FOR 2022. A granular product that is added onto the seed or directly to the furrow before planting and will treat up to 5 lbs of seed. Nitrogen inoculant contains a harmless bacteria which forms nodules on the roots of legumes. These turn nitrogen gas from the air into nitrogen fertilizer available for use by the plants. The increased yields (up to 60%) are especially noticeable for soils with low organic matter content, low pH soils and soils which haven't grown legumes before. Use inoculant to treat soil for growing garden legumes, including peas, beans and sweet peas.
