Kupanga sulphate ya ammoniumfeteleza ndi makhiristo oyera, monga omwe amapangidwa kuchokera ku coking kapena zina zopangidwa ndi petrochemical zopangidwa ndi utoto, wobiriwira kapena wachikasu wonyezimira. Zomwe zili musulphate ya ammoniumndi 20.5-21% ndipo imakhala 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.Sulphate ya ammoniumndi wolimba kutentha, koma zinthu 4 zamchere zikamagwira ntchito, zimatulutsanso mpweya wa ammonia monga feteleza onse a ammonium asafe. Pambuyo pakesulphate ya ammonium imagwiritsidwa ntchito m'nthaka, pang'onopang'ono imakulitsa acidity ya nthaka kudzera pakusankhidwa kwa mbewu, motero sulphate ya ammonium ndi chimodzimodzi ndi feteleza wa asidi.
Sulphate ya ammoniumNdi 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 sulphate ya ammoniumpopeza feteleza wa mbewu ayenera kukhala wocheperako, makamaka 10 kg pa mu, osakanikirana ndi feteleza wowola kasanu kapena kawiri kapena nthaka yachonde, samalani kuti musalumikizane ndi mbewu. Mukamabzala mbande za mpunga, nkhuku 5-10 zasulphate ya ammonium itha kugwiritsidwa ntchito pa ekala imodzi, kuphatikiza feteleza wowola, superphosphate, ndi zina zambiri, kuti apange slurry yopyapyala, yomwe imagwiritsidwa ntchito kusunsa mizu ya mbande, ndipo zotsatira zake ndizabwino kwambiri.
Mu dothi la acidic, sulphate ya ammonium ayenera kugwiritsidwa ntchito limodzi ndi manyowa a pafamu, ndipo ayenera kugwiritsidwa ntchito molumikizana ndi feteleza wa alkaline monga feteleza wa calcium magnesium phosphate ndi laimu (osasakanikirana) kuti acidity ya nthaka isakule.
Kugwiritsa ntchito sulphate ya ammoniumfeteleza m'munda wa paddy adzatulutsa hydrogen sulfide, yomwe imapangitsa mizu ya mpunga kukhala yakuda, yomwe ndi poizoni wa 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.
