  • Homogeneous granules of slow-release fertilizer and method of making the same
    Patent number: 6464746
    Abstract: A process for making homogeneous granules of slow-release fertilizer to deliver high doses of slow-release nitrogen in pellets that disperse or fall apart when contacted by moisture. The method includes mixing particles of slow-release nitrogen with particles of a potassium source and particles of a phosphorus source, to make a homogeneous blend of the particles. Then, the blended particles are moistened with water or an aqueous solution of urea to moisten the homogeneous blend. After moistening, the blended particles are contacted with an aqueous suspension of urea-formaldehyde resin to bind the particles into homogeneous granules. The aqueous suspension of urea formaldehyde resin preferably has a urea:formaldehyde ratio of about 1:1.
