ISingle Super Phosphate kwizichumisi zePhosphate
ISingle Super Phosphate (SSP), sesona sichumiso sephosphatic sithandwa kakhulu emva kweDAP njengoko sinezondlo zezityalo ezi-3 eziphambili ezizezi iPhosphorus, iSulfur kunye neCalcium kunye nemikhondo yezondlo ezincinci ezininzi. I-SSP iyafumaneka kwimveli kwaye ubonelelo lunokwenziwa ngesaziso esifutshane. I-SSP ngumthombo ogqwesileyo wezondlo ezintathu zezityalo. Icandelo le-P lisebenza emhlabeni ngokufanayo nakwezinye izichumisi ezinyibilikayo. Ubukho bazo zombini i-P kunye nesalfure(S) kwi-SSP inokuba lulutho lwezolimo apho zombini ezi zondlo zinqongopheleyo. Kuphononongo lwe-agronomic apho i-SSP ibonakaliswe ukuba yongamile kunezinye izichumisi ze-P, idla ngokuba ngenxa ye-S kunye/okanye i-Ca equlethwe nguye. Xa ifumaneka ekuhlaleni, i-SSP ifumene ukusetyenziswa okunabileyo kokuchumisa amadlelo apho zombini i-P kunye ne-S zifuneka khona. Njengomthombo we-P yodwa, i-SSP ihlala ibiza ngaphezulu kwezinye izichumisi ezigxininisiweyo, ngoko ke iye yehla ekuthandeni.
ISingle Superphosphate(SSP) yaba sisichumiso sokuqala seminerali esirhwebayo kwaye yakhokelela kuphuhliso lweshishini langoku lezondlo zezityalo. Esi sichumisi sasikade sesona sichumiso sisetyenziswa kakhulu, kodwa ezinye izichumisi ze-phosphorus(P) zithathe indawo ye-SSP ubukhulu becala ngenxa yesiqulatho se-P esisezantsi.

I-Phosphate yenye yeemveliso eziphambili zemfuno ye-phosphoric acid, ebalwa ngaphezu kwe-30%. Yenye yezinto zendalo phantse zonke ukutya. Njengesithako esibalulekileyo sokutya kunye nesongezo esisebenzayo, i-phosphate isetyenziswa ngokubanzi ekuqhubeni ukutya. I-China ityebile kwiimveliso ze-phosphate kunye ne-phosphate ezinomlinganiselo omkhulu wemveliso. Kukho malunga ne-100 iintlobo kunye neenkcukacha ze-phosphate kunye neemveliso ze-phosphide, kwaye iZongsheng inomthamo wemveliso ophantse ube zizigidi ezili-10 zeetoni. Iimveliso eziphambili ze-phosphoric acid, i-sodium tripolyphosphate, i-sodium hexametaphosphate, i-phosphate yokutya, i-phosphorus trichloride, i-phosphorus oxychloride, njl.
Okwangoku, imfuno yemveliso ye-phosphate esezantsi e-China ibuthathaka. I-phosphate yemveli efana ne-sodium tripolyphosphate iya kubangela ingxaki "ye-eutrophication" kwindawo yamanzi, umxholo we-sodium tripolyphosphate kwi-powder yokuhlamba uya kuncipha ngokuthe ngcembe, kwaye amanye amashishini aya kuthatha indawo ye-tripolyphosphate ye-sodium kunye nezinye iimveliso, ukunciphisa imfuno yamashishini asezantsi. Kwelinye icala, imfuno yeemveliso zeekhemikhali ezichanekileyo nezikhethekileyo ze-phosphorus ezifana ne-fosphoric acid ephakathi kunye ne-high-grade kunye ne-phosphate (ibakala le-elektroniki kunye nebakala lokutya), i-phosphate edibeneyo kunye ne-organic phosphate iye yanda ngokukhawuleza.
