Manyowa a ammonium sulphate ndi makhiristo oyera, monga omwe amapangidwa kuchokera ku coking kapena zina zopangidwa ndi petrochemical zopangidwa, ndi zotuwa, zofiirira kapena zachikasu. Zomwe zili ndi ammonium sulphate ndi 20.5-21% ndipo zili ndi asidi wochepa kwambiri. Imasungunuka mosavuta m'madzi ndipo imakhala yotsika kwambiri, koma imathanso kuyamwa chinyezi ndikuphatikizana nthawi yamvula, yomwe idzawononga thumba lonyamula. Samalani mpweya wabwino komanso kuuma nthawi yosungira. Ammonium sulphate imakhazikika kutentha, koma zinthu 4 zamchere zikamagwira ntchito, zimatulutsanso mpweya wa ammonia monga feteleza onse a ammonium nitrogen. Pambuyo pa ammonium sulphate itagwiritsidwa ntchito m'nthaka, pang'onopang'ono imakulitsa acidity ya nthaka kudzera pakusankhidwa kwa mbewu, chifukwa chake ammonium sulphate ndiyofanana ndi feteleza wa asidi. Ammonium sulphate ndi yoyenera nthaka yonse komanso mbewu zokonzedwa, ndi fungo la mbewu zokonda ammonium. Itha kugwiritsidwa ntchito ngati feteleza woyambira, kuvala pamwamba ndi feteleza wa mbewu. Pama feteleza wokakamiza, ndizochuma kwambiri komanso zothandiza kugwiritsira ntchito michere yambiri m'nthaka yapafupi ndi mizu m'masiku ochepa oyamba a mbewu. Komabe, iyenera kugwiritsidwa ntchito pakakhala kuti palibe timadontho ta madzi pa tsinde ndi tsamba pamwamba popewa kuwonongeka kwa mbewu. Kwa mpunga, iyenera kugwiritsidwa ntchito mozama kapena kuphatikiza ndi kulima minda kuti mupewe kutayika kwa klorini chifukwa cha nitrification ndi denitrification. Kuchuluka kwa ammonium sulphate ngati feteleza wa mbewu kuyenera kukhala kocheperako, makamaka makilogalamu 10 pa mu, osakanikirana ndi feteleza wabwinobwino kapena nthaka yachonde kasanu, samalani kuti musalumikizane ndi mbewu. Mukamabzala mbande za mpunga, katemera wa ammonium sulphate angagwiritsidwe ntchito pa ekala imodzi, kuphatikiza feteleza wowola, superphosphate, ndi zina zambiri, kuti apange slurry yopyapyala, yomwe imagwiritsidwa ntchito kusunsa mizu ya mbandezo, ndipo zotsatira zake zabwino kwambiri. M'nthaka ya acidic, ammonium sulphate iyenera kugwiritsidwa ntchito molumikizana ndi manyowa aulimi, ndipo iyenera kugwiritsidwa ntchito molumikizana ndi feteleza wa alkaline monga calcium magnesium phosphate feteleza ndi laimu (osasakanikirana ndi ntchito) kuteteza acidity ya nthaka kuwonjezeka. Kugwiritsa ntchito feteleza wa ammonium sulphate m'munda wa paddy kudzatulutsa hydrogen sulfide, yomwe imapangitsa mizu ya mpunga kukhala yakuda, yomwe ndi poizoni kwa mpunga, makamaka pamene mulingo wake ndi waukulu kapena wagwiritsidwa ntchito m'munda wakale wobwezeretsa, poyizoniyu amatha kuchitika. Gwiritsani akamba ndikuphatikiza zofunikira monga kulima ndi kuwotcha minda.
