Chakaita zvokugadzirwa ammonium sulphatemafetiraiza machena machena, akadai seaya akagadzirwa kubva pakubika kana kumwe kugadzirwa kwepetrochemical ne-zvigadzirwa, zvine cyan, shava kana yero yakajeka. Izvo zvirimo zveammonium sulphateiri 20.5-21% uye ine shoma shoma kwazvo yeasidhi acid. Iyo inonyungudika nyore nyore mumvura uye ine yakaderera hygroscopicity, asi inogona zvakare kutora mwando uye inosangana mumwaka wemvura, inozokanganisa bhegi rekutakura. Teerera kune mweya uye kuoma panguva yekuchengetedza.Ammonium sulphateyakagadzikana patembiricha yemukati, asi kana zvinhu zvina zvine alkaline zvikaita, inoburitsa gasi yeammonia senge mafetiraiza eamonium senitrogen. Pashureammonium sulphate inoiswa muvhu, zvishoma nezvishoma inowedzera acidity yevhu kuburikidza nekusarudza kwekudyara kwezvirimwa, saka ammonium sulphate yakafanana nefizikisi asidhi fetiraiza.
Ammonium sulphateinokodzera ivhu rakajairika uye zvirimwa zvakagadzirwa, uye hwema hweamonium-inoda zvirimwa. Inogona kushandiswa seyakagadzika fetiraiza, yepamusoro kupfeka uye mbeu fetiraiza. Kune fetiraiza yekumanikidza, zvinowedzera mari uye zvinoshanda kuisa huwandu hwakawanda hwezvikafu muvhu padyo nemidzi midzi mumazuva ekutanga ekukura kwezvirimwa. Zvisinei, inofanirwa kuiswa kana pasina madonhwe emvura pane hunde nemashizha pamusoro kudzivirira kukuvara kune chirimwa. Kune mupunga, inofanirwa kuiswa zvakadzama kana kusanganiswa neminda yekurima kudzivirira kurasikirwa neklorini nekuda kwe nitrification uye denitrification.
Huwandu hwe ammonium sulphatesezvo fetiraiza yembeu inofanira kunge iri diki, kazhinji makirogiramu gumi paamu, yakasanganiswa ne 5-10 nguva yakaora manyowa kana ivhu rakaorera, chenjera kuti usataure nembeu. Paunenge uchipinza michero yemupunga, mashanu kusvika mashanu emakati eammonium sulphate inogona kushandiswa paeka, ichibatanidzwa neyakaora manyowa, superphosphate, nezvimwewo, kugadzira slurry yakatetepa, iyo inoshandiswa kudzika midzi yemidziyo, uye maitiro acho akanaka kwazvo.
Mune ivhu rakaoma, ammonium sulphate inofanira kushandiswa pamwe chete nemupfudze wepurazi, uye inofanira kushandiswa pamwe chete nefetiraiza yealkaline yakadai secalcium magnesium phosphate fetiraiza uye lime (isina kusanganiswa musanganiswa) kudzivirira acidity yevhu kuwedzera.
Iko kushanda kwe ammonium sulphatefetiraiza mumunda wepaddy uchaburitsa hydrogen sulfide, zvinozoita kuti midzi yemupunga ive mitema, inova muchetura kune mupunga, kunyanya kana muyero wacho uri muhombe kana kuiswa mumunda wekare unodzosera, huturu uhu hunowanzoitika. Shandisa turtles uye ubatanidze matanho anodiwa sekurima uye kukisa minda.
