Idilesi yesulphate heptahydrate
Ukubonakala kwesulfate eyintsimbi yikristale emhlophe eluhlaza-luhlaza, yiyo loo nto ibizwa ngokuba "ngumgquba oluhlaza" kwezolimo. Isanti sulphate ubukhulu becala isetyenziswa kwezolimo ukulungisa i-pH yomhlaba, ukukhuthaza ukwenziwa kwe-chlorophyll, kunye nokuthintela isifo esityheli esibangelwa kukusilela kwentsimbi kwiintyatyambo nasemithini. Yinto ebaluleke kakhulu kwiintyatyambo ezithanda iasidi kunye nemithi, ngakumbi imithi yentsimbi. I-Ferrous sulfate iqulethe i-19-20% yentsimbi. Sisichumiso esihle sesinyithi, esilungele izityalo ezithanda i-asidi, kwaye sinokusetyenziswa rhoqo ukunqanda nokunyanga izifo ezityheli. Intsimbi iyimfuneko ekwenziweni kwe-chlorophyll kwizityalo. Xa intsimbi isilela, ukuyilwa kwe-chlorophyll kuyavalwa, kubangele ukuba izityalo ziphathwe yi-chlorosis, kwaye amagqabi ajike abe tyheli. Isisombululo esinamanzi se-ferrous sulfate sinokubonelela ngokuthe ngqo nge-iron enokufunxwa kwaye isetyenziswe zizityalo, kwaye inokunciphisa i-alkalinity yomhlaba. Ukusetyenziswa kwesulphate eyintsimbi, xa sithetha ngokubanzi, ukuba umhlaba wokubumba unkcenkceshelwa ngokuthe ngqo ngesisombululo se-0.2% -0.5%, kuya kubakho isiphumo esithile, kodwa ngenxa yentsimbi enyibilikayo kumhlaba ogalelweyo, iya kulungiswa ngokukhawuleza ikhompawundi engenakunyibilika ene-iron ayiphumeleli. Ke, ukunqanda ukulahleka kwezinto zentsimbi, isisombululo se-ferrous sulfate singasetyenziselwa ukutshiza izityalo kumagqabi.
