Njengesichumiso, i-urea yezolimo isetyenziswa kakhulu kwezolimo zanamhlanje ukuphucula ukuchuma komhlaba.Ngumthombo woqoqosho wenitrogen kwisondlo sezityalo kunye nokukhula.I-urea yaseTshayina inemilo eyahlukeneyo ngokuxhomekeke ekusetyenzisweni kwayo, kubandakanywa ifom yegranular, ifom ye powder njl.
Ukusetyenziswa kweUrea yezoLimo
Ngokuqhelekileyo, i-urea yezolimo ingasetyenziselwa njengesichumisi okanye njengento eluhlaza ekuveliseni ezinye izichumisi ezifana ne-ammonium nitrate kunye ne-calcium ammonium nitrate (CAN).Xa igalelwa emhlabeni okanye kwizityalo, inceda ukwandisa ukufumaneka kwenitrogen ngokuqhekeka ibe yimixube yeammonia ethi ifunxwe zizityalo.Oku kwandisa izivuno zezityalo kwaye kuphucula umgangatho kakhulu.Ukongeza kokugalelwa ngokuthe ngqo kwizityalo, urea yezolimo nayo inokuxutywa namanzi ngeenjongo zokunkcenkceshela okanye itshizwe emasimini emva kwexesha lokuvuna.
Izinto eziluncedo kwiUrea yaseTshayina
I-urea yaseTshayina ibonelela ngeenzuzo ezininzi xa kuthelekiswa nezichumisi zemveli ngenxa yomgangatho wayo ophezulu woxinaniso ngomthamo weyunithi nganye ngelixa useneendleko eziphantsi xa kuthelekiswa neminye imithombo yezichumisi zenitrogen ezifana ne-ammonium sulfate (AS) okanye i-potassium chloride (KCl).Ngaphaya koko, ayisuki lula kwimihlaba ngokungafaniyo ne-AS eyenza ilungele ukusetyenziswa kwexesha elide ngaphandle komngcipheko wongcoliseko lwamanzi aphantsi komhlaba akufutshane neziza zentsimi.Ngaphezu koko, ngenxa yokuba ifumaneka ngokulula kwiindawo ezininzi ezithengisa izinto zokulima eziqhelekileyo;oku kwenza ukuthenga kube lula kumafama ngakumbi abo bahlala kude nezixeko ezikhulu apho iivenkile ezikhethekileyo zisenokungabikho.
Okokugqibela njengoko imiyezo yezolimo iza ngeendlela ezahlukeneyo isenokulungelelaniswa ngokweemfuno ezithile ngokuxhomekeke kwiimeko zemozulu kunye nohlobo/ubudala/imeko yomhlaba olinywayo nto leyo edibanisa izinto eziluncedo ezinxulumene nokuwusebenzisa.
Ukuqukumbela
Ukuqukumbela i-Agricultural Ureas ibonelela ngesisombululo esisebenzayo sokuphucula amanqanaba okuchuma komhlaba kunye neempembelelo ezincitshisiweyo kwizinto eziphilayo nendalo ngokusebenzisa iindlela ezigxininisiweyo kunye nokufikeleleka lula ngamaxabiso afikelelekayo.Ubuchule babo bokugcina obulula bubenza ukuba babe nokhetho olufanelekileyo phakathi kwemithombo eyahlukeneyo yeNitrogenous Fertilizer ngaphandle phaya;ukwenza ukhetho olugqibeleleyo xa ujonge izisombululo zexesha elifutshane kunye nezexesha elide ngokufanayo.
