1) Potassium phosphate bụ ihe na-achịkwa acidity na ihe na-eme ka ihe dị ọcha (a na-eji ejikọta ion ígwè). Ọ na-egbochi nkụcha mmiri ma na-eji ya dị ka ihe na-eme ka acid sie ike na ntụ ntụ yana igbochi mkpụkọ ihe. Ọ na-eme ka ọrụ nke antioxidants dịkwuo elu.
2) N'ụlọ ọrụ nri (ihe mgbakwunye nri), a na-eji ya eme ihe dị ka ihe na-eme ka ihe sie ike, ihe na-eme ka potassium sie ike, ihe na-eme ka ihe na-esi ísì ụtọ, ihe na-ejikọ anụ. Potassium phosphate na-enyere aka ime ka ọ sie ike, mee ka ọ sie ike ma chịkwaa acidity na mmiri dị na nri. Dịka iwu nke FAO (1984) si dị, ojiji ya na oke ọnụọgụ dị ka ndị a: ofe ozugbo; nnu phosphate zuru oke: 1000 mg/kg (agbakọ dabere na P2O5); ụkwụ anụ ezi esiri esi, ham, anụ a gbuturu esiri esi 3g/kg (ọnụọgụ ojiji otu ma ọ bụ ọnụọgụ njikọta na phosphate ndị ọzọ, agbakọ na P2O5); ntụ mmiri ara ehi dị ala, mmiri ara ehi a gbuturu agbaji, ude a gwakọtara agwakọta: 2 g/kg (ọnụọgụ ojiji otu); ọnụọgụ njikọta na ihe ndị ọzọ na-eme ka ihe sie ike: 3 (agbakọ na ihe na-anaghị amịpụta mmiri); ntụ mmiri ara ehi, chiiz a gbuturu agbaji: 5g/kg; chiiz a gbuturu agbaji, mkpokọta phosphate 9g/kg (agbakọ dị ka phosphorus); ihe ọṅụṅụ oyi: 2g/kg (ọnụọgụ ojiji otu ma ọ bụ ọnụọgụ njikọta na phosphate ndị ọzọ, agbakọ na P2O5).
