Potaziyamu Sulphate
Potaziyamu sulphate ndi mchere wosakaniza ndi mankhwala a K chemical so ₄. Nthawi zambiri, zomwe zili mu K ndi 50% - 52%, ndipo zomwe zili mu S zili pafupifupi 18%. Sulphate yoyera ya potaziyamu ndiyopanda khungu, ndipo mawonekedwe a potaziyamu sulphate amakhala achikaso mopepuka. Potaziyamu sulphate ndi potaziyamu wabwino wosungunuka ndi potaziyamu chifukwa chotsika kwambiri, kutsika kochepa, mawonekedwe abwino komanso kugwiritsa ntchito bwino. Potaziyamu sulphate makamaka oyenera mbewu zachuma, monga fodya, mphesa, shuga beet, tiyi chomera, mbatata, fulakesi ndi mitengo ya zipatso zosiyanasiyana. Ndizomwe zimapangidwanso popanga feteleza wopanda chlorine, fosforasi, potaziyamu wa potaziyamu. Potaziyamu sulphate ndi mankhwala osalowerera ndale, feteleza wa asidi, omwe ali oyenera nthaka zosiyanasiyana (kupatula nthaka yodzaza madzi) ndi mbewu. Pambuyo pothira dothi, ion ya potaziyamu imatha kulowetsedwa mwachindunji ndi mbewu kapena kuyamwa ndi nthaka colloids. Zotsatira zake zidawonetsa kuti potaziyamu sulphate itha kugwiritsidwa ntchito ku mbewu za Cruciferae ndi mbewu zina zomwe zimafunikira sulfure wambiri panthaka yoperewera sulfa.
