Ugboro atọ superphosphate (TSP) bụ otu n'ime nyocha fatịlaịza P kachasị dị elu nke e jiri mee ihe na narị afọ nke 20. Na nka na uzu, amara ya dika calcium dihydrogen phosphate na monocalcium phosphate, [Ca (H2PO4) 2 .H2O]. Ọ bụ ezigbo P, ma ojiji ya ajụla ka fatịlaịza P ndị ọzọ ewuola ewu.
Mmepụta
Echiche nke mmepụta TSP dịtụ mfe. A na - emepụta TSP na - abụghị granular site na ịzaghachi obere ala phosphate na mmiri mmiri phosphoric acid na ngwakọta ụdị cone. Emere Granular TSP n'otu aka ahụ, mana a na-agba slurry na-akpata dị ka ihe mkpuchi na obere ihe iji wuo granulu nke oke achọrọ. Ngwaahịa ahụ sitere na ụzọ mmepụta abụọ ka enyere ọgwụgwọ maka ọtụtụ izu ka mmeghachi omume kemịkalụ nwayọ nwayọ. Ọgwụ na usoro nke mmeghachi omume ga-adịtụ iche dabere na akụrụngwa nke phosphate nkume.
Triple superphosphate na granular (egosiri) na ụdị ndị na-abụghị granular.
Iji Ugbo
TSP nwere ọtụtụ agronomic uru nke mere ka ọ bụrụ isi iyi P a ma ama kemgbe ọtụtụ afọ. O nwere ọdịnaya P nke kachasị elu nke fatịlaịza na-enweghị N. Ihe karịrị 90% nke ngụkọta P na TSP bụ mmiri agbaze, ya mere ọ na-aghọ ngwa ngwa maka ntinye osisi. Dika mmiri ala na-agbaze granulu, ihe ngwọta ala na-aghọ acidic. TSP nwekwara 15% calcium (Ca), na-enye ihe mgbakwunye ihe ọkụkụ ọzọ.
Otu isi ojiji nke TSP bụ na ọnọdụ ebe ọtụtụ fatịlaịza siri ike na-agwakọta ọnụ maka mgbasa ozi n'elu ala ma ọ bụ maka itinye ya na bandị dị n'okpuru ala. Ọ bụkwa ihe na-achọsi ike maka njikọta nke ihe ọkụkụ na-enwu enwu, dị ka alfalfa ma ọ bụ agwa, ebe ọ na-adịghị mkpa nsị N ọzọ iji gbakwunye ihe ndozi N.
Omume njikwa
Ewu ewu nke TSP agbadata n'ihi na ngụkọta ọdịnaya edozi (N + P2O5) dị ala karịa fatịlaịza ammonium dị ka monoammonium phosphate, nke iji ha tụnyere 11% N na 52% P2O5. Ọnụ ego nke imepụta TSP nwere ike ịdị elu karịa ammonium phosphates, na-eme ka akụnụba nke TSP ghara ịdị mma n'ọnọdụ ụfọdụ.
Ekwesịrị ịchịkwa fatịlaịza P niile iji zere ọghọm dị na mmiri mmiri site na mpaghara. Ihe site na ala ubi na mmiri dị nso na mmiri nwere ike itinye aka na mkpalite nke algae. Omume kwesịrị ekwesị nke njikwa edozi nwere ike ibelata ihe ize ndụ a.
Ndị Na-abụghị Ọrụ Ugbo
Monocalcium phosphate bụ ihe dị mkpa na-eme achịcha. Mmiri acid monocalcium phosphate na-arụ ọrụ site na ngwongwo alkaline iji mepụta carbon dioxide, na-eko achịcha maka ọtụtụ ngwaahịa. A na-agbakwunye monocalcium phosphate na nri anụ anụmanụ dị ka mgbakwunye dị mkpa ịnweta nke phosphate na Ca.
