Ngokubhekiselele kwimveliso yezolimo, ukusetyenziswa kwezichumisi zemichiza kudlala indima ebalulekileyo ekuqinisekiseni ukukhula kunye nesivuno sezityalo.Phakathi kweentlobo ezahlukeneyo zezichumiso ezifumaneka kwimarike,ibakala lobugcisa eprilled ureaibalasele njengokhetho oludumileyo phakathi kwamafama neengcaphephe kwezolimo.Kule bhlog, siza kujongisisa ukuba ithetha ukuthini i-urea yodidi lwegranular kunye nefuthe layo ekulinyweni kwezityalo.
Iprilled urea, ekwabizwa ngokuba yigranular urea, sisichumisi esisekwe kwinitrogen esetyenziswa kakhulu kwezolimo.Ngumthombo onexabiso eliphantsi wenitrogen eyimfuneko ekukhuleni nasekuphuhliseni izityalo.I-urea yomgangatho woshishino ibhekiselele kwi-urea ethe yafumana inkqubo ethile yokuvelisa ukuze ihlangabezane nemigangatho yomgangatho ofunekayo kwizicelo zezolimo.
Enye yeempawu eziphambili ze-urea yegranular ye-industrial yisayizi yayo efanayo kunye nomxholo ophezulu we-nitrogen.Oku kuqinisekisa ukusasazwa ngokulinganayo xa kugalelwe emhlabeni, kuvumela izityalo ukuba ziqhubeke kwaye zifunxe izondlo ngokufanelekileyo.Ukongeza, i-industrial-gradeurea granularayinabumdaka nezingcolisi, oko kuyenza ibe lukhetho oluthembekileyo nolukhuselekileyo lokuchumisa isityalo.
Ukusetyenziswa kwegranular yodidi lwe-urea kuzisa iinzuzo ezininzi kumafama nakubavelisi bezityalo.Okokuqala, inika izityalo ngomthombo ofikeleleka lula wenitrogen, ukukhuthaza ukukhula okunempilo nokuchuma.Oku kubaluleke ngakumbi kumanqanaba angundoqo okukhula kwesityalo, njengokuntshula, ukuhlakula nokudumba kweentyatyambo, apho iimfuno zenitrogen ziphezulu.
Ukongeza, i-urea yomgangatho wobugcisa inyibilika kakhulu emanzini kwaye inokufakwa emhlabeni ngokukhawuleza nalula.Oku kuthetha ukuba izityalo zinokufikelela ngokulula kwizondlo, ukuqinisekisa ukusetyenziswa ngokufanelekileyo kunye nenkcitho encinci.Ngenxa yoko, abalimi banokulindela ukuphuculwa kwezivuno zezityalo kunye nomgangatho, ekugqibeleni okukhokelela kwimbuyekezo yemali engcono.
Ukongeza kwiinzuzo zayo ze-agronomic, i-urea yegranular yodidi lweshishini nayo inegalelo kuzinzo lokusingqongileyo.Ngokubonelela ngokukhutshwa kwenitrogen elawulwayo nelungeleleneyo, inceda ukunciphisa umngcipheko wokuvuza kwezondlo kunye nokungcoliseka komhlaba.Oku kubalulekile ekugcineni ukuchuma kwexesha elide kunye nempilo yomhlaba, ngelixa kunciphisa impembelelo yokuphuma kwesichumisi kwimizila yamanzi.
Kuyafaneleka ukukhankanya ukuba umgangatho kunye nebakala le-granular urea lingahluka ngokuxhomekeke kumenzi kunye nenkqubo yokuvelisa.Ke ngoko, amafama kunye neengcali zezolimo bayacetyiswa ukuba bathenge i-urea yegranular yodidi lobugcisa kubaboneleli abathembekileyo ababambelela kumanyathelo olawulo olungqongqo lomgangatho.
Ngamafutshane, ibakala lobugcisaurea ehlanjululweyoibonelela ngomthombo wenitrogen othembekileyo nosebenzayo wokulinywa kwezityalo kwaye idlala indima ebalulekileyo kulimo lwangoku.Ubungakanani bamasuntswana afanayo, isiqulatho esiphezulu sesondlo kunye neenzuzo zokusingqongileyo zenza ukuba ibe lukhetho lokuqala kumafama ajonge ukukhulisa iindlela zokusebenza kwezolimo.Ngokuqonda ukubaluleka komgangatho wobugcisa we-urea, sinokulixabisa ngcono igalelo layo kulimo oluzinzileyo nolusebenzayo.
