Particulate Monoammonium Phosphate (Particulate MAP)
MAP tau ua cov chiv tseem ceeb rau ntau xyoo. Nws yog dej-soluble thiab dissolves sai heev nyob rau hauv txaus moist av. Thaum tawg, ob lub ntsiab lus tseem ceeb ntawm cov chiv cais dua kom tso tawm ammonium (NH4+) thiab phosphate (H2PO4-), ob qho tib si ntawm cov nroj tsuag vam khom rau kev noj qab haus huv, kev loj hlob. Cov pH ntawm cov tshuaj nyob ib puag ncig cov granule yog acidic me ntsis, ua MAP ib qho tshwj xeeb tshaj yog xav tau chiv nyob rau hauv nruab nrab- thiab high-pH av. Cov kev tshawb fawb Agronomic qhia tau tias, nyob rau hauv feem ntau, tsis muaj qhov sib txawv tseem ceeb hauv P khoom noj khoom haus ntawm ntau yam kev lag luam P chiv nyob rau hauv feem ntau.
MAP yog siv rau hauv cov tshuaj tua hluav taws qhuav uas muaj nyob hauv chaw ua haujlwm, tsev kawm ntawv thiab tsev. Cov tshuaj tua hluav taws tua hluav taws tua cov hmoov zoo MAP, uas npog cov roj thiab ua kom cov nplaim taws sai sai. MAP tseem hu ua ammonium phosphate monobasic thiab ammonium dihydrogen phosphate.
