Abstract:Large granular coated fertilizers show higher fertilizer efficiency and nutrient utilization ratio than small granules; the large granules have smaller specific surface area, can save considerable coating materials, and lower production cost and application cost; the large granules lessen soil pollution and are convenient to use. The development of large granular coated fertilizers is an important route for popularization of the difficult-to-promote slow-release and controlled release fertilizers.
Keywords:coated fertilizers large granules development trend
