Feteleza siachilendo kwa alimi m'magawo ambiri. Manyowa ochuluka amafunikira pafupifupi chaka chilichonse. Ntchito yayikulu ya feteleza ndikukonza nthaka komanso kukonza chonde. Ndi imodzi mwazinthu zofunikira pakupanga ulimi; Komabe, feteleza wophatikiza amatanthauza feteleza wamankhwala wokhala ndi zinthu ziwiri kapena zingapo zopatsa thanzi. Manyowa ophatikizika ali ndi zabwino zokhala ndi michere yambiri, zigawo zochepa zothandizira ndi zinthu zabwino zakuthupi. Ndikofunikira kwambiri kuti pakhale feteleza woyenera, kukonza magwiritsidwe a feteleza, ndikulimbikitsa zokolola zambiri komanso zokhazikika. zotsatira;

Njira wamba za granulation wa fetereza wapakompyuta ndi izi: ng'anjo yamagetsi, kusungunula chimbale, kutsitsi granulation, nsanja yayikulu, ndi zina zambiri. Njira yayikulu kwambiri yosungunulira njira ya granulation imagwiritsa ntchito feteleza wa nayitrogeni wambiri. Ukadaulo uwu umapopera potaziyamu wa nitrogeni-phosphate wosungunuka kuchokera pamwamba pa nsanja ya granulation, ndipo umasonkhana mu granules kwinaku ikuzizira munsanjayo. Izi zimatchedwanso kusungunuka kwa granulation. M'makampani ogwiritsa ntchito ammonium nitrate, granulation yosanja yayikulu imagwiritsidwa ntchito. Njira yogwiritsira ntchito feteleza wamagulu ili ndi maubwino awa:
Choyamba, imatha kugwiritsa ntchito njira ya ammonium nitrate yothetsera, kuthetsa kufunikira kwa njira ya utsi wa utsi wa ammonium nitrate yankho, komanso kugwiritsidwa ntchito kwa olimba ammonium nitrate kupanga feteleza wamagulu, zomwe zimapangitsa kuti magwiritsidwe ntchito azikhala ochepa. Onetsetsani kuti mukugwiritsa ntchito mosamala.
Chachiwiri ndikuti kusungunuka kwa magudumu oyenda mozungulira kumagwiritsa ntchito mphamvu ya kutentha kwa yankho la ammonium nitrate, ndipo chinyezi chimakhala chotsika kwambiri, chifukwa chake palibe chifukwa chokhalira chosasangalatsa, chomwe chimapulumutsa kwambiri mphamvu.
Chachitatu ndikutha kugwiritsa ntchito feteleza wokhala ndi nayitrogeni wambiri. Mankhwalawa amakhala ndi mawonekedwe osalala komanso ozungulira, kuchuluka kwakukulu, sikophweka kuphatikizana, komanso kusungunuka mosavuta. Izi zimatsimikizira kuti malonda ake ali ndi mwayi wopikisana nawo pamtengo wabwino komanso mtengo wake kuchokera kuukadaulo wogwiritsa ntchito.
