M'gawo laulimi wamafakitale ndi zopanga, kufunikira kwamankhwala apamwamba ndi feteleza ndikofunikira. Mmodzi wofunikira wotere ndimonoammonium phosphate(MAP), chinthu chosunthika komanso chothandiza chomwe chimagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana. Chifukwa cha mawonekedwe ake ang'onoang'ono komanso apamwamba kwambiri, MAP yakhala yankho lazosankha pamagwiritsidwe osiyanasiyana.
MAPndi gulu lomwe lili ndi 11% nayitrogeni ndi 52% phosphorous, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito feteleza ndi mafakitale. Kusungunuka kwake kwakukulu komanso kutulutsa kwachangu kwa michere kumapangitsa kuti ikhale yofunika kwambiri pazaulimi, kupereka zakudya zofunika kwa zomera ndi mbewu. Kuphatikiza apo, mawonekedwe ake ang'onoang'ono ndi osavuta kugwiritsa ntchito ndikugwiritsa ntchito, kupangitsa kuti ikhale njira yabwino pazaulimi zazikulu.
Pankhani ya ntchito zamafakitale, MAP imagwiritsidwa ntchito kwambiri popanga zoletsa moto, zowonjezera zakudya zanyama, komanso ngati zotchingira m'njira zochizira madzi. Kusinthasintha kwake ndi khalidwe lapamwamba zimapangitsa kukhala chisankho choyamba kwa mafakitale omwe amafunikira mankhwala odalirika komanso ogwira mtima.
Chimodzi mwazinthu zazikulu zomwe zimasiyanitsa MAP yapamwamba kwambiri ndi chiyero chake komanso kusasinthika. Industrial monoammonium phosphate imapangidwa pogwiritsa ntchito njira zotsogola kuti zitsimikizidwe kuti ndi zapamwamba kwambiri komanso magwiridwe antchito. Izi zikutanthauza kuti mabizinesi atha kudalira MAP kuti ipereke zotsatira zosasinthika, kaya pakupanga feteleza kapena kupanga mafakitale.
Monoammonium phosphate granularimaperekanso mwayi wapadera. Kukula kwake kwa tinthu ting'onoting'ono komanso kusavuta kunyamula kumapangitsa kuti ikhale yabwino kusankha kusakanikirana ndi feteleza kapena mankhwala ena. Izi zimalola kugwiritsa ntchito moyenera ndikuwonetsetsa kugawidwa kwazakudya, kulimbikitsa kukula bwino ndi zokolola m'malo aulimi.
Mu ulimi, kugwiritsa ntchitomono ammonium phosphate wokhala ndi mawonekedwe apamwambazasonyezedwa kuonjezera zokolola za mbewu ndi kupititsa patsogolo thanzi la zomera. Kuphatikizika kwake kwa nayitrogeni ndi phosphorous kumapangitsa zomera kukhala ndi gwero lazakudya zokwanira komanso kumalimbikitsa kukula kwa mizu. Izi zimapangitsa kukhala chida chofunikira kwa alimi ndi akatswiri azaulimi omwe akufuna kukulitsa zokolola ndikutulutsa mbewu zapamwamba.
Kuphatikiza apo, kusungunuka kwamadzi kwa MAP kumapangitsa kuti zakudya zizitha kupezeka mosavuta ndi zomera, zomwe zimalimbikitsa kuyamwa mwachangu ndikugwiritsa ntchito. Izi ndizopindulitsa makamaka m'madera omwe nthaka ili ndi dothi losauka kapena kumene zomera zimafuna kudya mwamsanga.
Pomaliza, granular monoammonium phosphate yapamwamba ndi chinthu chofunikira kwambiri pazaulimi wamafakitale ndi mafakitale. Kusinthasintha kwake, kudalirika komanso kugwira ntchito bwino kumapanga chisankho choyamba cha ntchito zosiyanasiyana, kuyambira kupanga feteleza kupita ku mafakitale. Ndi kuthekera kochulukitsa zokolola, kukonza thanzi la mbewu ndikuthandizira ntchito zamafakitale, MAP ndi umboni wa mphamvu zamapangidwe apamwamba kwambiri kuti zithandizire kupita patsogolo ndi zokolola m'mafakitale.
