Diammonium Phosphate (DAP) giredhi rekudya inowanzoshandiswa phosphorus nenitrogen fetereza iyo inogona kushandiswawo sechikafu chekudya mukudya kwemhuka.Inoumbwa neammonium uye phosphate ions, ichipa zvose zvakakosha zvekudya pakukura nekukura kwemhuka.
DAP giredhi rekudya rinowanzo ine yakakwira phosphorus (inenge 46%) uye nitrogen (inenge 18%), zvichiita kuti ive yakakosha sosi yezvikafu izvi mukudya kwemhuka.Phosphorus yakakosha kune akasiyana mabasa emuviri, kusanganisira kuumbwa kwemapfupa, simba metabolism, uye kubereka.Nitrogen inoita basa rakakosha muprotein synthesis uye kukura kwese.
Kana yaiswa mukudya kwemhuka, giredhi rekudya reDAP rinogona kubatsira kuzadzisa phosphorus uye nitrogen zvinodiwa zvezvipfuyo nehuku, kukurudzira kukura kune hutano, kubereka, uye kubereka kwese.
Zvakakosha kufunga nezvezvinodiwa zvinovaka muviri zvemhuka uye kushanda nenyanzvi yezvokudya zvinovaka muviri kana chiremba wemhuka kuti aone chiyero chakakodzera chekubatanidzwa kweDAP giredhi rekudya mukugadzira chikafu.
