Katatu wapamwamba phosphate(TSP) feteleza ndi gawo lofunikira paulimi wamakono ndipo amagwira ntchito yofunika kwambiri pakukulitsa zokolola. TSP ndi feteleza wofufuzidwa kwambiri wa phosphate wokhala ndi 46% phosphorous pentoxide (P2O5), ndikupangitsa kuti ikhale gwero labwino kwambiri la phosphorous ku zomera. Kuchuluka kwake kwa phosphorous kumapangitsa kukhala michere yofunika kwambiri pakukula kwa mbewu, chifukwa phosphorous ndiyofunikira pakusamutsa mphamvu, photosynthesis ndi kukula kwa mizu. M'nkhaniyi, tiwona njira zosiyanasiyana zogwiritsira ntchito feteleza wa TSP kuti athandize alimi kukulitsa zokolola.
Mmodzi mwa ubwino waukulu waFeteleza wa TSPali ndi phosphorous wambiri, womwe ndi wofunikira pakulimbikitsa kukula kwa mizu yolimba. Mukathira TSP, ndikofunikira kuwonetsetsa kuti feteleza wayikidwa pafupi ndi mizu ya mbewuyo. Izi zitha kuchitika kudzera mu njira zomangira kapena zoyatsira mbali, pomwe TSP imayikidwa mumizere yokhazikika pafupi ndi mizere ya mbewu kapena pakati pa mizere. Poyika TSP pafupi ndi mizu, zomera zimatha kuyamwa phosphorous bwino, kupititsa patsogolo kukula kwa mizu ndi kukula kwa zomera zonse.
Njira ina yabwino yogwiritsira ntchito feteleza wa TSP ndikuphatikiza nthaka. Njirayi imaphatikizapo kusakaniza TSP m'nthaka musanabzale kapena kufesa mbewu. Pophatikiza TSP m'nthaka, alimi amatha kuwonetsetsa kuti phosphorous imagawidwa mofanana m'madera onse a mizu, kupereka chakudya chokhazikika chakukula kwa zomera. Kumanga kwa dothi kumakhala kopindulitsa makamaka kwa mbewu zomwe zili ndi mizu yambiri chifukwa zimathandiza kuti phosphorous igawike mofanana m'nthaka, kulimbikitsa kukula ndi chitukuko.
Kuphatikiza pa ukadaulo woyika, ndikofunikiranso kuganizira nthawi yogwiritsira ntchito TSP. Pa mbewu zapachaka, tikulimbikitsidwa kugwiritsa ntchito TSP musanabzale kapena kufesa kuti phosphorous ipezeke mosavuta ku mbande pamene zikukhazikitsa mizu yake. Kwa mbewu zosatha, monga mitengo kapena mipesa, TSP ingagwiritsidwe ntchito kumayambiriro kwa masika kuti ithandizire kukula ndi maluwa. Pokhazikitsa nthawi ya ntchito za TSP kuti zigwirizane ndi kukula kwa mbewu, alimi amatha kukulitsa mapindu a feteleza ndikulimbikitsa kukula kwa mbewu zathanzi.
Kuyanjana kwaMtengo wa TSPndi zakudya zina m'nthaka ziyenera kuganiziridwanso. Kupezeka kwa phosphorous kungakhudzidwe ndi zinthu monga nthaka pH, organic matter ndi kupezeka kwa zakudya zina. Kuyesa nthaka kungapereke chidziwitso chamtengo wapatali pa mlingo wa michere ya nthaka ndi pH, kulola alimi kupanga zisankho zomveka za kuchuluka kwa momwe angagwiritsire ntchito TSP ndi nthawi yake. Pomvetsetsa kayendesedwe ka michere ya nthaka, alimi atha kupititsa patsogolo kagwiritsidwe ntchito ka TSP pofuna kuonetsetsa kuti zomera zikulandira phosphorous yokwanira munyengo yonse yolima.
Mwachidule, feteleza wa triple phosphate (TSP) ndi zida zofunika kwambiri pakukulitsa zokolola, makamaka polimbikitsa kukula kwa mizu ndi kukula kwa mbewu zonse. Pogwiritsa ntchito njira zogwirira ntchito zogwirira ntchito monga kudula mizere, kulumikiza nthaka ndi nthawi yoyenera, alimi atha kuonetsetsa kuti TSP ikupereka phosphorous yofunikira kuti mbewu zikule bwino. Kuphatikiza apo, kumvetsetsa kayendesedwe ka michere m'nthaka ndi kuyezetsa nthaka kungawonjezere mphamvu ya ntchito za TSP. Pophatikiza ukadaulo uwu muzaulimi, alimi amatha kugwiritsa ntchito feteleza wa TSP ndikukulitsa zokolola.
