Forms, properties and dissolution of controlled-release nitrogenous fertilisers uri icon


  • The forms, properties and dissolution rates of controlled-release nitrogenous fertilizers are reviewed. These materials belong to one of the categories: coated materials, uncoated sparingly-water-soluble inorganic and organic compounds. Physical and chemical properties of the fertilizer materials are described along with their dissolution characteristics. Information on indigenous materials proposed as controlled-release N sources is scarce and is required to evaluate their comparative efficacy
