Njengomanyolo, i-urea yezolimo isetshenziswa kakhulu kwezolimo zanamuhla ukuthuthukisa ukuvunda komhlabathi. Iwumthombo ukongayo we-nitrogen wokondleka kwezitshalo nokukhula. I-urea yaseShayina inomumo ohlukile ngokuya ngokusetshenziswa kwayo okuhlosiwe, kufaka phakathi ifomu le-granular, ifomu lempushan njll.
Isicelo Of Agricultural Urea
Ngokuvamile, i-urea yezolimo ingasetshenziswa njengomanyolo noma njengento eluhlaza ekukhiqizeni amanye ama-fertilizer afana ne-ammonium nitrate ne-calcium ammonium nitrate (CAN). Uma ifakwe enhlabathini noma ezitshalweni, isiza ukwandisa ukutholakala kwe-nitrogen ngokuhlephula ibe yinhlanganisela ye-ammonia bese imuncwa izitshalo. Lokhu kwandisa isivuno sezitshalo futhi kuthuthukisa ikhwalithi kakhulu. Ngaphezu kokufaka okuqondile ezitshalweni, i-urea yezolimo ingaxutshwa namanzi ngenhloso yokunisela noma ifuthwe emasimini ngemva kwenkathi yokuvuna.
Izinzuzo ze-Chinese Urea
I-urea yaseShayina ihlinzeka ngezinzuzo eziningi uma iqhathaniswa nezivundisi zendabuko ngenxa yezinga layo eliphezulu lokugxilisa ingqondo ngeyunithi ngayinye kuyilapho inezindleko eziphansi uma iqhathaniswa neminye imithombo kamanyolo we-nitrogenous njenge-ammonium sulfate (AS) noma i-potassium chloride (KCl). Ngaphezu kwalokho, ayisuki kalula enhlabathini ngokungafani ne-AS okwenza ilungele ukusetshenziswa kwesikhathi eside ngaphandle kobungozi bokungcoliswa kwamanzi angaphansi komhlaba ezindaweni zasensimini eziseduze. Ngaphezu kwalokho, ngenxa yokuthi itholakala kalula ezindaweni eziningi ezithengisa izinto ezivamile zokulima; lokhu kwenza ukuthenga kube lula kubalimi ikakhulukazi labo abahlala kude namadolobha amakhulu lapho izitolo ezikhethekile kungenzeka zingekho.
Okokugcina njengoba urea wezolimo eza ngezinhlobo ezahlukene angalungiselelwa izidingo ezithile kuye ngezimo zezulu kanye nohlobo/ubudala/isimo somhlaba olinywayo obuye wengeze izici eziwusizo ezihlobene nokusetshenziswa kwawo.
Isiphetho
Sengiphetha I-Agricultural Ureas ihlinzeka ngesixazululo esisebenza kahle sokuthuthukisa amazinga okuvunda enhlabathini ngomthelela oncishisiwe wezinto eziphilayo nendawo yazo ezungezile ngokusebenzisa izinhlobo zawo ezigxilile ezihambisana nokutholakala kalula ngamanani akholekayo . Amandla abo okugcina abenza babe ukukhetha okuhle phakathi kwemithombo yoMquba Yenitrojeni eyahlukene laphaya; ukubenza bakhethe kahle uma ubheka izixazululo zesikhathi esifushane nezesikhathi eside ngokufanayo.
