I-Triple superphosphate (TSP) ibilolunye lohlalutyo oluphezulu lwezichumisi ezaye zasetyenziswa kakhulu kwinkulungwane yama-20. Ngokobuchwephesha, yaziwa njenge calcium dihydrogen phosphate kwaye njenge monocalcium phosphate, [Ca (H2PO4) 2 .H2O]. Ngumthombo obalaseleyo we-P, kodwa ukusetyenziswa kwayo kuye kwancipha njengoko ezinye izichumisi ze-P ziye zithandwa kakhulu.

Imveliso
Umxholo wemveliso yeTSP ulula. I-non-granular TSP iveliswa ngokuxhaphakileyo ngokuphendula ilitye le-phosphate yomhlaba ococekileyo kunye ne-phosphoric acid engamanzi kumxube we-cone. I-TSP yegranular yenziwa ngokufanayo, kodwa islurry esiphumela sifezelwa njengesiqhoboshi kumasuntswana amancinci ukwakha iigreyina zobungakanani obufunayo. Imveliso evela kuzo zombini iindlela zokuvelisa ivumelekile ukuba inyange iiveki ezininzi njengoko ukusabela kweekhemikhali kugqitywa kancinci. I-chemistry kunye nenkqubo yempendulo iya kwahluka ngandlela thile ngokuxhomekeka kwiimpawu zelitye le-phosphate.
I-superphosphate kathathu kwi-granular (ibonisiwe) kunye neefom ezingezo-granular.
Ukusetyenziswa kwezolimo
I-TSP inezibonelelo ezininzi ze-agronomic ezenze ukuba zibe ngumthombo weP othandwayo kangangeminyaka emininzi. Inowona mxholo uphezulu we-P wezichumiso ezomileyo ezingenayo i-N. Ngaphezulu kwe-90% yetotali ye-P kwi-TSP inyibilikiswa ngamanzi, ngoko ke ifumaneka ngokukhawuleza xa kuthathwa izityalo. Njengoko ukufuma komhlaba kunyibilikisa igranule, isisombululo somhlaba esimanzi siba neasidi. I-TSP ikwanayo ne-15% calcium (Ca), ebonelela ngesongezelelo sezityalo.
Ukusetyenziswa okukhulu kwe-TSP kukwimeko apho izichumisi ezininzi ezixutyiweyo zidityanisiwe ukusasaza emhlabeni okanye ukufaka isicelo kwibhanti egxunyekwe ngaphantsi komhlaba. Kuyanqweneleka ukuchumisa kwezityalo ezinemidumba, ezinje ngealfalfa okanye iimbotyi, apho kungekho manyathelo ongezelelweyo okuchumisa afunekayo ukongeza ukulungiswa komzimba we-N.

Izenzo zoLawulo
Ukuthandwa kwe-TSP kuye kwehla ngenxa yokuba umxholo wezondlo (i-N + P2O5) ungaphantsi kunezichumisi ze-ammonium phosphate ezinje nge-monoammonium phosphate, ethelekisa i-11% N kunye ne-52% P2O5. Iindleko zokuvelisa i-TSP zinokuphakama kune-ammonium phosphates, ezenza ukuba uqoqosho lwe-TSP lungathandeki kwezinye iimeko.
Zonke izichumisi ze-P kufuneka zilawulwe ukunqanda ilahleko kumanzi abalekayo aphuma emasimini. Ilahleko ye-Phosphorus isuka kumhlaba wezolimo ukuya kufutshane namanzi angaphezulu komhlaba kunokuba negalelo kukhuthazo olungafunekiyo lokukhula kwe-algae. Iindlela ezifanelekileyo zokulawula izondlo kunokuwunciphisa lo mngcipheko.
Ukusetyenziswa okungekho kwezolimo
I-Monocalcium phosphate yinto ebalulekileyo ekubhakeni i-powder. Imonidcium phosphate ene-asidi iphinda isebenze kunye nealkaliyali yokuvelisa icarbon dioxide, egwele kwiimveliso ezininzi ezibhakiweyo. I-Monocalcium phosphate ihlala yongezwa kwizidlo zezilwanyana njengokongezwa kwezimbiwa kubalulekile kuzo zombini iphosphate kunye neCa.
