Particulate Monoammonium Phosphate (Particulate MAP)
MAP yakhala feteleza wofunikira wa granular kwa zaka zambiri. Imasungunuka m'madzi ndipo imasungunuka mwachangu m'dothi lonyowa mokwanira. Akasungunuka, zigawo ziwiri zazikulu za feteleza zimasiyanitsidwanso kuti atulutse ammonium (NH4+) ndi phosphate (H2PO4-), zonse zomwe zomera zimadalira kuti zikule bwino. PH ya yankho lozungulira granule imakhala ya acidic pang'ono, zomwe zimapangitsa MAP kukhala feteleza wofunikira kwambiri mu dothi lopanda ndale komanso lapamwamba la pH. Kafukufuku wa agronomic akuwonetsa kuti, nthawi zambiri, palibe kusiyana kwakukulu pazakudya za P pakati pa feteleza wa P osiyanasiyana wamalonda nthawi zambiri.
MAP imagwiritsidwa ntchito muzozimitsa moto wamankhwala owuma omwe amapezeka m'maofesi, masukulu ndi m'nyumba. Chozimitsa chozimira chimabalalitsa MAP ya ufa wosalala, womwe umakwirira mafuta ndikuzimitsa motowo mwachangu. MAP imadziwikanso kuti ammonium phosphate monobasic ndi ammonium dihydrogen phosphate.
