1. Mukurima, kushandiswa kwefetereza kwakakosha kusimudzira kukura kwezvirimwa zvine hutano uye kuwedzera goho rezvirimwa.
2. Granular urea ine amoniya yakasiyana uye munyu kuravira uye initrogen-yakapfuma fetireza inoita basa rakakosha mukusimudzira kukura kwechirimwa. Kana yaiswa paivhu, inoita hydrolysis process, ichiburitsa ammonium ions inobatwa nyore nemidzi yezvirimwa. Izvi zvinowedzera kutora nitrogen, nokudaro zvichikurudzira kukura nekukura kwembesa.

1. Imwe yemabhenefiti makuru egranular urea ndeyekunyungudika kwayo kwakanyanya mumvura uye madoro akasiyana-siyana, zvichiita kuti zvive nyore kushandisa uye kuve nechokwadi chekubatwa kwakanaka kwezvinovaka muviri nemiti.
2. Kuchinja-chinja kwayo uye kufambirana nenzira dzakasiyana dzemashandisirwo dzakadai senhepfenyuro, kupfeka kwepamusoro kana fertigation inoita kuti ive sarudzo yekutanga kune varimi vari kutsvaga kukwidziridza maitiro ekutarisira fetiraiza.
3. chimiro chemakemikari chegranularurea, kusanganisira kuparara kwayo kuita biuret, ammonia uye cyanic acid pane tembiricha yepamusoro, inosimbisa kugona kwayo kwekudzora kusunungurwa uye mhedzisiro inogara kwenguva refu pakudya kwezvirimwa. Izvi zvinoita kuti ive yakanakira kuenderera mberi kwekupa kudya kunovaka muviri mumwaka wekukura, zvichideredza kudiwa kwekugara uchinyorerazve.
