controlled release nitrogen fertilizer using biochar as a renewable support matrix

摘要

Controlled Release of Nitrogen Fertilizer Using Bio-Charcoal as a Renewable Support Matrix This invention is directed to an ecofertilizer comprising a urea-based granulate nitrogen-controlled organic fertilizer fertilizer using biochar as a renewable support matrix. also relates to a process for producing a controlled release nitrogen fertilizer such as the ecofertilizer of this invention. biochar is obtained by the pyrolysis temperature of 300 ° C from agricultural waste; and is used as a renewable matrix by nitrogen impregnation. subsequently, urea impregnated biochar is encapsulated using a biodegradable polymer. Encapsulation was performed by a precipitation method. The developed controlled release nitrogen fertilizer developed showed substantially complete nitrogen availability as a plant nutrient.
