I-Triple superphosphate (TSP) ibingomunye womanyolo wokuqala wokuhlaziya okuphezulu owasetshenziswa kakhulu ngekhulu lama-20. Ngokobuchwepheshe, yaziwa njenge-calcium dihydrogen phosphate futhi njenge-monocalcium phosphate, [Ca (H2PO4) 2 .H2O]. Ungumthombo omuhle kakhulu we-P, kepha ukusetshenziswa kwayo kwehlile njengoba eminye imanyolo ye-P seyithandwa kakhulu.

Ukukhiqizwa
Umqondo wokukhiqizwa kwe-TSP ulula. I-TSP engeyona imbumbumbulu ivame ukukhiqizwa ngokuphendula idwala le-phosphate elicolekile lomhlabathi nge-liquid phosphoric acid kumxube wohlobo lwesigaxa. I-Granular TSP yenziwa ngokufanayo, kepha i-slurry evelayo ifafazwa njengokumboza ezinhlayiyaneni ezincane ukwakha ama-granules osayizi oyifunayo. Umkhiqizo ovela kuzindlela zombili zokukhiqiza uvunyelwe ukwelashwa amasonto ambalwa njengoba ukusabela kwamakhemikhali kuqedwa kancane. I-chemistry kanye nenqubo yokuphendula kuzohluka ngandlela thile ngokuya ngezici zedwala le-phosphate.
I-superphosphate ephindwe kathathu kumafomu ayimbudumbudu (abonisiwe) namafomu angewona ayimbudumbudu.
Ukusetshenziswa Kwezolimo
I-TSP inezinzuzo eziningana zezolimo ezenze ukuthi ibe ngumthombo odumile weP iminyaka eminingi. Inokuqukethwe okungu-P okuphezulu kakhulu kukamanyolo owomile ongenayo i-N.Ngaphezulu kwama-90% we-P ephelele ku-TSP kuncibilikiswa ngamanzi, ngakho-ke kutholakala ngokushesha ukutholwa kwezitshalo. Njengoba umswakama wenhlabathi uncibilikisa i-granule, isixazululo somhlabathi esiminyene siba yi-asidi. I-TSP iqukethe ne-15% calcium (Ca), inikezela ngesakhi sezithako esengeziwe.
Ukusetshenziswa okukhulu kwe-TSP kusezimeni lapho umanyolo oqinile uhlanganiswe ndawonye ukusakazwa ebusweni bomhlabathi noma ukufaka isicelo ebhandini eligxiliwe ngaphansi komhlaba. Kuyinto efiselekayo futhi ukukhulelwa kwezitshalo ezinemidumba, njenge-alfalfa noma ubhontshisi, lapho kungadingeki khona ukuvundiswa okungeziwe kwe-N ukwengeza ukulungiswa kwe-N.

Imikhuba Yezokuphatha
Ukuthandwa kwe-TSP kwehlile ngoba ingqikithi yokuqukethwe kwezakhi (i-N + P2O5) ingaphansi kukamanyolo we-ammonium phosphate ofana ne-monoammonium phosphate, okuthe ngokuqhathanisa iqukethe u-11% N no-52% P2O5. Izindleko zokukhiqiza i-TSP zingaphakama kune-ammonium phosphates, okwenza ezomnotho ze-TSP zingabi nhle kwezinye izimo.
Yonke imanyolo ka-P kufanele iphathwe ukuvikela ukulahleka kokugeleza kwamanzi okuphuma emasimini. Ukulahleka kwe-phosphorus kusuka emhlabeni wezolimo kuya emanzini angaphezulu angasiza ekuvuseleleni okungathandeki kokukhula kwe-algae. Izindlela ezifanele zokuphathwa kwezakhi zinganciphisa le ngozi.
Ukusetshenziswa Okungeyona Kwezolimo
I-Monocalcium phosphate iyisithako esibalulekile ekuphekeni i-powder. I-acidic monocalcium phosphate isebenza ne-alkaline ingredient ukukhiqiza isikhutha, okuyimvubelo yemikhiqizo eminingi ebhakwe. I-Monocalcium phosphate ivame ukungezwa ekudleni kwezilwane njengesengezo esibalulekile samaminerali sobabili i-phosphate neCa.
