Nimin, a neemcontaining
triterpenes that act as nitrogen inhibitors and thus
ensures slow release of nitrogen by leaching and also ensures
continuous supply of nitrogen to the plants. The basic concept
of controlled-release or slow-release fertilizers is that they
release their nutrient contents at more gradual rates that permit
maximum uptake and utilization of the nutrient while minimizing
losses due to leaching, volatilization or excessive turf growth
