CONTROLED LIBERATION PRODUCT, PRODUCT BASED ON CONTROLED FREEDOM URITY, AND PROCEDURES FOR PARTICULAR TREATMENT, NUTRIENT FOOD ON PLANTS AND NUTRIENT FOOD ON RUMINERS." Controlled release urea-based feed supplements for ruminant animals and nutrients from controlled release urea-based plants are comprised of particles or granules comprising either the whole or the main part of the urea or having urea on or on the external surfaces of these,and a moisture-resistant interpenetration polymer network coating in the included particles of the reaction products of urea and polyisocyanate, and polyisocyanate reaction products, an alkyd resin having at least a dual connection in each repeated unit and an oil having at least a double connection, the double bonds being reactive to one or the other and to themselves. Coated plant nutrients have a substantially linear rate of nutrient release to the soil over a controlled period of time, for example,30 to 120 days. Coated ruminant feeding supplements have a substantially linear rate of NPN release in the rume over a controlled period of time, e.g. 12 to 24 hours. The nutrient ratio for controlling agents is high, controlled release is achieved with minimal expense, and products are economical to use.
