Abstract
Methods of making and using a superabsorbent starch graft copolymer involve producing starch graft copolymers having particle sizes useful in granule applicators for application to agricultural fields. Starch graft copolymers applied to field crops provide excellent anti-crusting properties, increased seed germination and stand, increased crop growth, increased yields, and reduced water requirements.
