This fine milled Alfalfa Meal Soil Amendment affects soil as though you had planted a cover crop. As a legume, alfalfa is naturally high in nitrogen. It also benefits soil microorganisms by helping them convert soil nutrients into soluble forms more available to plants. Finally, alfalfa contains the naturally occurring growth hormone, Triacontanol, which boosts the growth rates of seedlings. Alfalfa Meal Fertilizer makes an excellent mulch for roses and other perennials, as well as a great additive for composts. Recommended application: 5-10kg/10 square meters.
