ABSTRACT:
The growth of microorganisms in stored crops, and especially in animal feedstuffs, is inhibited by the application of a preservative composition which comprises ammonia, urease enzyme urea and/or urea polymers in a fluid medium. Urea polymers which are useful include biuret, triuret, cyanuric acid, urea cyanurate and other compounds which decompose to form ammonia. The effect of treatment with the preservative composition is to provide an immediate microorganism-inhibiting ammonia level, which, due to delayed decomposition of the urea and urea polymers, is sustained to some significant degree during prolonged storage of the treated material.
