Controlled release urea-based feed supplements for ruminant animals and controlled release urea-based plant nutrients are comprised of particles or granules comprised in whole or in principal part of urea or having urea at or on the exterior surfaces thereof, and a moisture resistant interpenetrating polymer network coating on the particles comprised of the reaction products of urea and a polyisocyanate, and the reaction products of polyisocyanate, an alkyd resin having at least one double bond in each repeat unit and an oil having at least one double bond, the double bonds being reactive with one another and with themselves. The coated plant nutrients have a substantially linear rate of release of nutrients to the soil over a controlled period of time, e.g., 30 to 120 days. The coated ruminant feed supplements have a substantially linear rate of NPN release in the rumen over a controlled period of time, e.g., 12 to 24 hours. The ratio of nutrients to control agents is high, controlled release is achieved at minimal expense, and the products are economical to use.
