Incazelo Yemikhiqizo
Incazelo Yomkhiqizo: I-Urea, eyaziwa nangokuthi i-carbamide, inefomula yamakhemikhali ethi CH4N2O.Kuyi-organic compound eyakhiwa i-carbon, i-nitrogen, i-oxygen, ne-hydrogen.Kuyikristalu emhlophe.
I-Urea iwumanyolo we-nitrogen ogxilile kakhulu, umanyolo ongathathi hlangothi osebenza ngokushesha, futhi ungasetshenziswa futhi ukukhiqiza umanyolo ohlukahlukene oyinhlanganisela.I-Urea ifaneleka kumanyolo oyisisekelo kanye nokugqoka okuphezulu, futhi ngezinye izikhathi njengomanyolo wembewu.
Njengomanyolo ongathathi hlangothi, i-urea ilungele inhlabathi nezitshalo ezahlukahlukene.Kulula ukuyigcina, kulula ukuyisebenzisa, futhi inomonakalo omncane emhlabathini.Kuyikhemikhali ye-nitrogen fertilizer esetshenziswa njengamanje ngenani elikhulu.Embonini, i-ammonia ne-carbon dioxide isetshenziselwa ukuhlanganiswa kwe-urea ngaphansi kwezimo ezithile.
Isicelo: Ezolimo njengomanyolo
Iphakheji:25 kgs/isikhwama noma njengoba ucela.
Isitoreji:Umkhiqizo kufanele ugcinwe ezindaweni ezinomthunzi nezipholile.Ungalivumeli libekwe elangeni.Ukusebenza ngeke kuthinteke ngokuswakama.
Amazinga Asetshenzisiwe:I-International Standard.
Ukucaciswa komkhiqizo:
