Potassium sulphate
Potassium sulfate bụ nnu inorganic na usoro kemịkalụ nke K Ψ so ₄. N'ozuzu, ọdịnaya nke K bụ 50% - 52%, na ọdịnaya nke S bụ ihe dịka 18%. Ezigbo potassium sulfate bụ kristal na-enweghị ntụpọ, na ọdịdị nke potassium potassium sulfate bụ nke na-acha odo odo. Potassium sulfate bụ ezigbo mmiri soluble potassium fatịlaịza n'ihi na nke ala hygroscopicity, ala na-eri nri, ezi ahụ Njirimara na-adaba adaba ngwa. Potassium sulphate kachasị mma maka mkpụrụ akụ na ụba, dị ka ụtaba, mkpụrụ vaịn, sugar beet, osisi tii, poteto, flax na osisi mkpụrụ osisi dị iche iche.
