Performance analysis of chicken manure coated slow-release urea fertilizer (CM-CSRUF)

Abstract. Slow-release fertilizers (SRFs) are developed, to halt the nutrient loss environment, either by coating urea or infusing in a hydrophobic material. SRFs reduces release that point where single application of fertilizer can meet demand plants. Diverse range materials have already been utilized produce SRFs, however several disadvantages such hydrophilicity, non-biodegradability and crystallinity limit their scale up. Herein, we reported production using chicken manure with paraffin wax as binder. Nitrogen test coated revealed only 11.8% total nutrients were released first 12 h whereas uncoated ≥99.9 % nutrients. Ritger-Peppas model was found best fit kinetic data an R2 value 0.97.
