Fertilizer compositions, processes of making them, and pocesses of using them

摘要

Relates to a fertilizer product in granular form, to processes for making and using it. The granules have strength, sizes and weights suitable for mechanical dispensing and application to and into the soil. These granules combine particles of a nitrogen source of poor solubility in pH 7 water at 20 DEG C., that converts slowly to a useful form, together with a binder that holds these fine particles together.
