  • Preparation of material useful as plant nutrients
    Patent number: 4404015
    Abstract: A plant nutrient composition is obtained by extracting a complex fraction comprising a mixture of water-insoluble long-chain organic compounds from natural plant material, especially from rice bran wax. The fraction is preferably obtained by saponifying rice bran wax and recovering the unsaponifiable residue. The fraction can be employed in dilute aqueous emulsion form as a foliar spray to enhance the growth and yield of many crops, such as rice, wheat and maize, especially in marginal agricultural areas.
