Ingcaciso yeMveliso:
I-Urea, ekwabizwa ngokuba yi-carbamide, inefomula yeekhemikhali i-CH4N2O. Yikhompawundi ephilayo eyenziwe yikhabhoni, initrogen, ioksijini kunye nehydrogen. Yikristale emhlophe.
I-Urea sisichumiso senitrogen esixutywa kakhulu, isichumisi esingathathi hlangothi esisebenza ngokukhawuleza, kwaye sinokusetyenziswa ukuvelisa iintlobo ezahlukeneyo zezichumisi ezihlanganisiweyo. I-Urea ifanelekile kwisichumiso esisisiseko kunye nesinxibo esiphezulu, kwaye ngamanye amaxesha njengesichumisi sembewu.
Njengesichumisi esingathathi hlangothi, i-urea ifanelekile kwimihlaba eyahlukeneyo kunye nezityalo. Kulula ukuyigcina, kulula ukuyisebenzisa, kwaye inomonakalo omncinci emhlabeni. Yikhemikhali ye-nitrogen fertilizer esetyenziswa ngoku kwisixa esikhulu. Kumashishini, i-ammonia kunye ne-carbon dioxide zisetyenziselwa ukudibanisa urea phantsi kweemeko ezithile.
Isicelo:
Ezolimo njengesichumiso.
Umqulu:25 kgs/ibhegi okanye njengoko ucela.
Ugcino:Imveliso kufuneka igcinwe kwindawo enomthunzi kunye nepholile. Musa ukuyivumela ukuba ibekwe elangeni. Ukusebenza akuyi kuchaphazeleka ngokufuma.
ImigangathoExesikiwe:Umgangatho wamazwe ngamazwe.
