Abstract:
An attrition and shatter resistant plant nutrient/pesticide briquette composition which slowly releases biologically active materials and plant nutrients to plants in soil, the composition comprises:(a) slow release plant nutrient particles, exhibiting diameters of between 0.5 and 5.0 millimeters, amounting to between 50 and 95 percent of the briquette;(b) pesticide sorption particles, exhibiting diameters of between 0.5 and 5.0 millimeters and an ability to sorb and reduce leachability of liquid pesticides, amounting to between 2 and 45 percent of the briquette;(c) liquid pesticide amounting to between 0.1 and 10.0 percent of the pesticide sorption solids sorbed on the pesticide sorption solids;(d) an adhesive, amounting to between 2 and 20 percent of the briquette, exhibiting effective adhesion to the particles of slow release plant nutrients and the pesticide sorption solids, and a solubility of less than 0.1 gram per 100 grams of water, the adhesive coating the particles of the plant nutrients and the pesticide sorption solids; and,(e) the adhesive coated particles being formed into briquettes by pressing into dies at a pressure and temperature sufficient to make the briquettes attrition and shatter resistant.
