1. Kwezolimo, ukusetyenziswa kwezichumisi kubalulekile ukukhuthaza ukukhula kwezityalo okunempilo kunye nokwandisa isivuno sezityalo.
2. Urea lweGranular ine-ammonia kunye nencasa enetyuwa eyahlukileyo kwaye sisichumiso esityebile ngenitrogen esidlala indima ebalulekileyo ekukhuthazeni ukukhula kwezityalo. Xa igalelwe emhlabeni, ingena kwinkqubo ye-hydrolysis, ikhupha i-ammonium ion ezifunxwa lula ziingcambu zezityalo. Oku kwandisa ukuthathwa kwenitrogen, ngokwenjenjalo kukhuthaza ukukhula nophuhliso lwezityalo.
3. Kwezolimo, ukusetyenziswa kwezichumisi kubalulekile ukukhuthaza ukukhula kwezityalo okunempilo nokwandisa isivuno sezityalo.
1. Enye yeenzuzo eziphambili ze-granular urea yi-solubility yayo ephezulu emanzini kunye ne-alcohols ehlukeneyo, okwenza kube lula ukuyifaka kunye nokuqinisekisa ukuthathwa ngokufanelekileyo kwezondlo zizityalo.
2. Ukuguquguquka kwayo kunye nokuhambelana neendlela ezahlukeneyo zokufaka izicelo ezifana nosasazo, ukunxitywa okuphezulu okanye ukuchumisa kwenza kube lukhetho lokuqala kumafama ajonge ukukhulisa iindlela zokulawula izichumiso.
3. ukubunjwa kweekhemikhali zegranularurea, kubandakanywa ukubola kwayo kwi-biuret, i-ammonia kunye ne-cyanic acid kumaqondo aphezulu aphezulu, igxininisa amandla ayo okukhutshwa okulawulwayo kunye nemiphumo ehlala ixesha elide kwisondlo sezityalo. Oku kuyenza ibe yinto efanelekileyo kunikezelo lwezondlo oluqhubekayo kulo lonke ixesha lokukhula, ukunciphisa imfuno yokuphinda kufakwe izicelo rhoqo.
