Mayelana nokukhiqiza kwezolimo, ukusetshenziswa kukamanyolo wamakhemikhali kudlala indima ebalulekile ekuqinisekiseni ukukhula kanye nesivuno sezitshalo.Phakathi kwezinhlobo ezahlukene zikamanyolo ezitholakala emakethe,I-urea ehlanganisiwe yezinga lobuchwepheshekugqama njengokukhetha okuthandwayo phakathi kwabalimi nochwepheshe bezolimo.Kule bhulogi, sizobhekisisa ukuthi kusho ukuthini i-urea ye-granular yezinga lezimboni kanye nomthelela wayo ekutshalweni kwezitshalo.
I-Prilled urea, eyaziwa nangokuthi i-granular urea, ingumanyolo osuselwa ku-nitrogen osetshenziswa kakhulu kwezolimo.Iwumthombo we-nitrogen ongabizi kakhulu obalulekile ekukhuleni nasekuthuthukisweni kwezitshalo.I-urea yezinga lezimboni isho i-urea eye yabhekana nenqubo ethile yokukhiqiza ukuze ihlangabezane namazinga ekhwalithi adingekayo ekusetshenzisweni kwezolimo.
Esinye sezici eziyinhloko ze-urea ye-granular yezinga lezimboni ubukhulu bezinhlayiyana ezifanayo kanye nokuqukethwe kwe-nitrogen ephezulu.Lokhu kuqinisekisa ukusatshalaliswa okulinganayo lapho kufakwe emhlabathini, okuvumela izitshalo ukuthi zimunce imisoco ngokuqhubekayo nangempumelelo.Ukwengeza, i-industrial-gradeurea granularayinakho ukungcola kanye nokungcola, okwenza kube ukukhetha okuthembekile nokuphephile kokuvundiswa kwezitshalo.
Ukusetshenziswa kwe-urea granular yezinga lezimboni kuletha izinzuzo eziningi kubalimi nabakhiqizi bezitshalo.Okokuqala, inikeza izitshalo umthombo we-nitrogen otholakala kalula, okhuthaza ukukhula okunempilo nokuchuma.Lokhu kubaluleke kakhulu ngezigaba ezibalulekile zokukhula kwezitshalo, njengokuhluma, ukulima nokuqhakaza, lapho izidingo ze-nitrogen ziphezulu.
Ukwengeza, i-urea yezinga lobuchwepheshe incibilika kakhulu emanzini futhi ingasetshenziswa emhlabathini ngokushesha nakalula.Lokhu kusho ukuthi izitshalo zikwazi ukufinyelela kalula imisoco, ukuqinisekisa ukusetshenziswa kahle kanye nokumosha okuncane.Ngenxa yalokho, abalimi bangalindela ukuvunwa kwezitshalo okuthuthukisiwe kanye nekhwalithi, ekugcineni kuholele ekubuyiseleni okungcono kwezezimali.
Ngaphezu kwezinzuzo zayo ze-agronomic, i-urea ye-granular yezinga lezimboni nayo inomthelela ekusimameni kwemvelo.Ngokuhlinzeka ngokukhululwa kwe-nitrogen okulawulwayo nokulinganiselayo, kusiza ukunciphisa ingozi yokucwiliswa kwezakhi kanye nokungcoliswa komhlabathi.Lokhu kubalulekile ekugcineni ukuvunda kwesikhathi eside nempilo yomhlabathi, kuyilapho kunciphisa umthelela wokugeleza kukamanyolo emanzini.
Kuyafaneleka ukusho ukuthi ikhwalithi kanye nebanga le-granular urea lingahluka kuye ngomkhiqizi kanye nenqubo yokukhiqiza.Ngakho-ke, abalimi kanye nochwepheshe bezolimo bayelulekwa ukuthi bathenge i-urea ye-granular yezinga lobuchwepheshe kubahlinzeki abahloniphekile ababambelela ezinyathelweni eziqinile zokulawula ikhwalithi.
Ngamafuphi, ibanga lobuchwephesheurea ehlutshiweinikeza umthombo we-nitrogen othembekile nosebenza kahle wokutshalwa kwezitshalo futhi idlala indima ebalulekile kwezolimo zesimanje.Ubukhulu bayo bezinhlayiyana ezifanayo, okuqukethwe okuphezulu komsoco kanye nezinzuzo zemvelo kwenza kube ukukhetha kokuqala kubalimi abafuna ukuthuthukisa izinqubo zezolimo.Ngokuqonda ukubaluleka kwe-urea yezinga lobuchwepheshe, singabonga kangcono igalelo layo kwezolimo ezisimeme futhi eziphumelelayo.
