Triple superphosphate i loko o ka Phosphate Fertilizers
Triple superphosphate （TSP）, Hana ʻia e ka phosphoric acid concentrated a me ka pōhaku lepo phosphate. He wai hoʻoheheʻe phosphate kiʻekiʻe ia, a hoʻohana nui ʻia no nā lepo he nui. Hiki ke hoʻohana ʻia e lilo i mea hoʻomomona maʻamau, mea hoʻomomona hou, fertilizer germ a me nā mea maka no ka hana ʻana i nā mea kanu.
ʻO TSP kahi mea hoʻomomona kiʻekiʻe, hiki ke hoʻoheheʻe ʻia i ka wai, a ʻo kona ʻano phosphorus maikaʻi he 2.5 a 3.0 mau manawa ma mua o ka calcium maʻamau (SSP). Hiki ke hoʻohana ʻia ka huahana e like me ka fertilizer base, ka lole luna, ka mea kanu a me nā mea maka no ka hoʻokumu ʻana i nā mea momona; hoʻohana nui ʻia i ka laiki, ka palaoa, ke kulina, ka sorghum, ka pulupulu, nā huaʻai, nā mea kanu a me nā mea ʻai ʻē aʻe a me nā mea kanu waiwai; hoʻohana nui ʻia i ka lepo ʻulaʻula a me ka lepo melemele , ʻO ka lepo Brown, ka lepo fluvo-aquic melemele, ka lepo ʻeleʻele, ka lepo kinamona, ka lepo poni, ka lepo albic a me nā ʻano lepo ʻē aʻe.
E hoʻohana i ke ʻano kemika kuʻuna (Den method) no ka hana ʻana.
Hoʻopili ka pauka pōhaku Phosphate (slurry) me ka ʻakika sulfuric no ka hoʻokaʻawale ʻana i ka wai-paʻa e loaʻa ai ka waika phosphoric dilute i ka wai. Ma hope o ka noʻonoʻo ʻana, loaʻa ka phosphoric acid concentrated. Hoʻopili ʻia ka phosphoric acid a me ka pauka pōhaku phosphate (hoʻokumu ʻia i kemika), a hoʻopaʻa ʻia nā mea pane a hoʻopaʻa ʻia, granulated, maloʻo, kānana, (inā pono, anti-caking package), a hoʻomaha ʻia e loaʻa ai ka huahana.
ʻO ka superphosphate, ka mea i kapa ʻia ʻo ka superphosphate maʻamau, he mea kanu phosphate i hoʻomākaukau pono ʻia e ka decomposing pōhaku phosphate me ka sulfuric acid. ʻO nā mea waiwai nui ka calcium dihydrogen phosphate hydrate Ca (H2PO4) 2 · H2O a me kahi liʻiliʻi o ka waika phosphoric manuahi, a me ka calcium sulfate anhydrous (pono no ka lepo sulfur deficient). Loaʻa ka calcium superphosphate i ka 14% ~ 20% P2O5 pono (80% ~ 95% o ia mea e hoʻoheheʻe ʻia i ka wai), nona ka wai-soluble quick acting phosphate fertilizer. Hiki ke hoʻohana pololei ʻia ka pauka keʻokeʻo hina a hinahina paha e like me ka mea hoʻomomona phosphate. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui no ka hana ʻana i nā mea hoʻohuihui.
ʻO kahi mea momona ʻeleʻele a hina hina paha. Hiki ke hoʻoheheʻe ʻia ka hapa nui o lākou i ka wai, a ʻaʻole hiki ke hoʻoheheʻe ʻia kekahi i ka wai a hiki ke hoʻoheheʻe ʻia i ka 2% citric acid (citric acid solution).
