Pākuʻi Monoammonium Phosphate (Particulate MAP)
He mea waiwai nui ka MAP no nā makahiki he nui.Hiki ke hoʻoheheʻe ʻia i ka wai a hoʻoheheʻe koke ʻia i ka lepo maʻamau.I ka hemo ʻana, hoʻokaʻawale hou nā ʻāpana kumu ʻelua o ka mea hoʻomomona e hoʻokuʻu i ka ammonium (NH4+) a me ka phosphate (H2PO4-), ʻo ia mau mea kanu ʻelua e hilinaʻi nei no ka ulu mau ʻana.ʻO ka pH o ka hoʻonā e hoʻopuni ana i ka granule he ʻawaʻawa haʻahaʻa, e hoʻolilo iā MAP i mea hoʻomomona i makemake nui ʻia ma nā ʻāina kū ʻole a pH kiʻekiʻe.Hōʻike nā haʻawina agronomic, ma lalo o ka nui o nā kūlana, ʻaʻohe ʻokoʻa koʻikoʻi i ka meaʻai P ma waena o nā mea kanu P pāʻoihana ma lalo o ka hapa nui o nā kūlana.
Hoʻohana ʻia ʻo MAP i nā mea kinai ahi maloʻo i loaʻa mau ma nā keʻena, nā kula a me nā home.Hoʻopuehu ʻia ka MAP pauka maikaʻi ʻia e ka mea hoʻopau kinai, kahi e uhi ai i ka wahie a hoʻopau koke i ka lapalapa.Ua ʻike ʻia ʻo MAP he ammonium phosphate monobasic a me ammonium dihydrogen phosphate.
