Coated seeds and process for coating seeds
Abstract
Abstract A NEW PROCESS FOR COATING SEEDS FOR PLANTING IS DESCRIBED. SEEDS ARE INITIALLY COATED WITH FINELY-GROUND, POROUS PARTICLES, E.G., HEAT EXPANDED VERMICULITE, DAMPENING THEM ONLY ENOUGH TO CAUSE THE VERMICULITE PARTICLES TO ADHERE TO THE NATURAL SEED COAT AND TO EACH OTHER. WHEN THE SEED IS COMPLETELY COATED AN OVERCOAT IS APPLIED. THE OVRCOAT COMPRISES FINELY-GROUND POROUS PARTICLES APPLIED WITH A BONDING AGENT COMPRISING ABOUT EQUAL PARTS POLYVINYL ACETATE AND POLYVINYL ALCOHOL WITH ENOUGH WATER TO MAKE THE AGENT SPRAYABLE. SMALL SEEDS TO COATED GERMINATE SUBSTANTIALLY AS QUICKLY AS UNCOATED SEEDS AND TOTAL GERMINATION IS COMPARABLE. SMALL SEEDED VEGETABLE CROPS CAN BE PLANTED TO A STANT WITH AVAILABLE PRECISION PLANTERS.
