1. Ammonium sulphate amagwiritsidwa ntchito kwambiri ngati feteleza wa nayitrogeni. Amapereka N kwa NPK.Amapereka mlingo wofanana wa nayitrogeni ndi sulfure, amakumana ndi kuchepa kwa sulfure kwakanthawi kochepa kwa mbewu, msipu ndi zomera zina.
2. Kutulutsa mwachangu, kuchita mwachangu;
3. Kuchita bwino kwambiri kuposa urea, ammonium bicarbonate, ammonium chloride, ammonium nitrate;
4. Atha kuphatikizidwa mosavuta ndi feteleza ena. Ili ndi zinthu zofunika za agronomic kukhala gwero la nayitrogeni ndi sulfure.
5. Ammonium sulphate imapangitsa kuti mbewu zizikula bwino komanso kuti zibereke bwino komanso kuti zithe kupirira tsoka, zitha kugwiritsidwa ntchito ngati dothi wamba komanso kubzala mu feteleza wofunikira, feteleza wowonjezera ndi manyowa ambewu. Oyenera mbande mpunga, paddy minda, tirigu ndi tirigu, chimanga kapena chimanga, kukula kwa tiyi, masamba, mitengo ya zipatso, udzu udzu, udzu, kuwaika ndi zomera zina.
Kugwiritsa ntchito kwambiri ammonium sulphate ndi monga feteleza wa dothi lamchere. M'nthaka ammonium ion imatulutsidwa ndikupanga asidi pang'ono, kutsitsa pH ya nthaka, pomwe imathandizira nayitrogeni wofunikira pakukula kwa mbewu. Choyipa chachikulu pakugwiritsa ntchito ammonium sulphate ndi kuchepa kwa nayitrogeni poyerekeza ndi ammonium nitrate, zomwe zimakweza mtengo wamayendedwe.
Amagwiritsidwanso ntchito ngati chothandizira chaulimi chamankhwala osungunuka m'madzi, ma herbicides, ndi fungicides. Kumeneko, imagwira ntchito yomanga zitsulo zachitsulo ndi calcium zomwe zimapezeka m'maselo amadzi ndi zomera. Ndiwothandiza makamaka ngati adjuvant wa 2,4-D (amine), glyphosate, ndi glufosinate herbicides.

Ammonium sulfate precipitation ndi njira yodziwika bwino yoyeretsera mapuloteni ndi mvula. Pamene mphamvu ya ionic ya yankho ikuwonjezeka, kusungunuka kwa mapuloteni mu njirayo kumachepa. Ammonium sulphate imasungunuka kwambiri m'madzi chifukwa cha chikhalidwe chake cha ayoni, chifukwa chake imatha "kutulutsa mchere" mapuloteni ndi mvula. Chifukwa cha kuchuluka kwa dielectric m'madzi, ma ion amchere omwe amasiyanitsidwa kukhala cationic ammonium ndi anionic sulfate amasungunulidwa mosavuta m'zipolopolo za hydration za mamolekyu amadzi. Kufunika kwa chinthu ichi pakuyeretsa zinthu kumachokera ku kuthekera kwake kukhala ndi madzi ochulukirapo poyerekeza ndi mamolekyu ambiri omwe si polar kotero kuti mamolekyu ofunikira a nonpolar amalumikizana ndikutuluka munjirayo mokhazikika. Njirayi imatchedwa salting out ndipo imafuna kugwiritsa ntchito mchere wambiri womwe ungathe kusungunuka mumadzi osakaniza. Kuchuluka kwa mchere womwe umagwiritsidwa ntchito poyerekeza ndi kuchuluka kwa mchere womwe uli mu osakaniza ukhoza kusungunuka. Momwemonso, ngakhale kuti kuchuluka kwakukulu kumafunikira kuti njirayo igwire ntchito ndikuwonjezera mchere wambiri, wopitilira 100%, ungathenso kuchulukitsa yankho, motero, kuyipitsa mpweya wosagwirizana ndi mchere. Kuchuluka kwa mchere wamchere, komwe kungapezeke mwa kuwonjezera kapena kuonjezera kuchuluka kwa ammonium sulfate mu njira yothetsera, kumathandizira kupatukana kwa mapuloteni chifukwa cha kuchepa kwa mapuloteni; kulekana uku kungapezeke mwa centrifugation. Kugwa kwa mpweya ndi ammonium sulfate ndi chifukwa cha kuchepa kwa kusungunuka m'malo mwa kusungunuka kwa mapuloteni, motero mapuloteni omwe amatha kusungunuka amatha kusungunuka pogwiritsa ntchito mabafa wamba.[5] Ammonium sulphate mpweya umapereka njira yosavuta komanso yosavuta yogawanitsa zosakaniza zama protein.
Pakuwunika ma latisi a raba, mafuta osasinthika amawunikidwa ndi mphira wothira ndi 35% ammonium sulfate solution, yomwe imasiya madzi omveka bwino momwe mafuta osasunthika amapangidwanso ndi sulfuric acid kenako amathiridwa ndi nthunzi. Mvula yosankha yokhala ndi ammonium sulphate, motsutsana ndi njira yanthawi zonse yamvula yomwe imagwiritsa ntchito acetic acid, sikusokoneza kutsimikiza kwamafuta acids osakhazikika.
