Izithako zomanyolo i-ammonium sulphate zingamakristalu amhlophe, njengalawo enziwe ngokukhipha noma ngomunye umkhiqizo wemikhiqizo eyenziwe ngophethilomu, onombala o-cyan, onsundu noma ophuzi ngokukhanyayo. Okuqukethwe kwe-ammonium sulphate kungama-20.5-21% futhi kuqukethe inani elincane kakhulu le-asidi yamahhala. Iyancibilika kalula emanzini futhi ine-hygroscopicity ephansi, kepha futhi ingamunca umswakama futhi ihlangane ngezikhathi zezimvula, okuzokonakalisa isikhwama sokupakisha. Naka umoya omncane kanye nokoma ngesikhathi sokugcina. I-ammonium sulphate izinzile ekamelweni lokushisa, kepha lapho izinto ezine ezine-alkaline zisebenza, ibuye ikhiphe igesi ye-ammonia njengawo wonke umanyolo we-ammonium nitrogen. Ngemuva kokuthi i-ammonium sulphate isetshenzisiwe emhlabathini, izokhula kancane kancane i-acidity yenhlabathi ngokumuncwa okukhethiwe kwezitshalo, ngakho-ke i-ammonium sulphate iyefana nomanyolo we-physiological acid. I-ammonium sulphate ilungele inhlabathi ejwayelekile nezitshalo ezilungisiwe, nephunga lezitshalo ezithanda i-ammonium. Ingasetshenziswa njengomanyolo oyisisekelo, ukugqoka okuphezulu kanye nomanyolo wembewu. Kumanyolo ophoqelelwa, kuyonga kakhulu futhi kuyasebenza ukufaka inani elikhulu lezakhamzimba enhlabathini eseduze kohlelo lwempande ezinsukwini zokuqala ezimbalwa zokukhula kwesitshalo. Kodwa-ke, kufanele isetshenziswe uma engekho amaconsi amanzi esiqwini nasendaweni yamaqabunga ukugwema ukulimala kwesitshalo. Irayisi, kufanele lisetshenziswe ngokujula noma lihlanganiswe nezinsimu zokutshala ukugwema ukulahleka kwe-chlorine ngenxa ye-nitrification ne-denitrification. Inani le-ammonium sulphate njengomanyolo wembewu kufanele libe lincane, imvamisa i-10 kg nge-mu ngayinye, ixutshwe nomanyolo opholile ophindwe ka-5-10 noma umhlabathi ovundile, qaphela ukuthi ungaxhumani nembewu. Lapho ufaka kabusha izithombo zerayisi, kungasetshenziswa amakati ama-5-10 we-ammonium sulphate ngehektare ngalinye, kuhlanganiswe nomanyolo owonakele, i-superphosphate, njll., Ukwenza i-slurry encane, esetshenziselwa ukucwilisa izimpande zezithombo, futhi umphumela Kuhle kakhulu. Enhlabathini ene-asidi, i-ammonium sulphate kufanele isetshenziswe ngokuhlangana nomquba wasepulazini, futhi kufanele isetshenziswe ngokuhlangana nomanyolo we-alkaline onjenge-calcium magnesium phosphate fertilizer kanye ne-lime (hhayi okuxutshiwe) ukuvimbela i-acidity yenhlabathi ukuthi ingakhuli. Ukusetshenziswa kukamanyolo we-ammonium sulphate ensimini ye-paddy kuzokhiqiza i-hydrogen sulfide, ezokwenza izimpande zelayisi zibe mnyama, okuyingozi elayisi, ikakhulukazi lapho isilinganiso sikhulu noma sisetshenziswe enkambeni endala yokubuyisela, lo shevu kungenzeka zenzeka. Sebenzisa izimfudu futhi uhlanganise izinyathelo ezidingekayo njengokutshala nokugaya izinkambu.
