Cov khoom siv tshuaj lom neeg ntawm matrix feem ntau suav nrog tus nqi pH, tus nqi conductivity, cation pauv kev ua tau zoo, cov as-ham thiab dej zoo.
pH tus nqi: Tus nqi pH ntawm matrix cuam tshuam rau daim ntawv, solubility thiab kev ua tau zoo ntawm cov as-ham. Hauv kev tsim khoom, cov matrix yuav tsum muaj qhov ruaj khov acidity thiab alkalinity. Feem ntau hais lus, tus nqi pH ntawm matrix yuav tsum yog 5.5 ~ 7.5. pH tus nqi yog qhov ntsuas ntawm hydrogen ion concentration hauv cov tshuaj thiab ntsuas ntawm acidity thiab alkalinity ntawm cov tshuaj.
Conductivity tus nqi: qhia txog tus nqi ntawm soluble ntsev Ameslikas nqa nyob rau hauv lub matrix, uas ncaj qha cuam tshuam qhov sib npaug ntawm cov as-ham thiab kev loj hlob ntawm cov nroj tsuag. Feem ntau, cov ntsiab lus ntsev soluble hauv matrix yuav tsum tsis pub tshaj 1000 mg / kg, nyiam dua tsawg dua lossis sib npaug li 500 mg / kg.
Cation pauv kev ua tau zoo: Lub peev xwm pauv cation (CEC tus nqi) yog qhia raws li tus naj npawb ntawm centimoles ntawm cations hloov los ntawm 1000 grams ntawm matrix. Feem ntau, 10 ~ 100 centimoles / kg yog qhov tsim nyog dua. Cation txauv kev ua tau zoo yog qhov taw qhia tseem ceeb rau kev ntsuas lub peev xwm ntawm matrix khaws cia thiab tso tawm cov khoom noj.
Khoom noj khoom haus thiab dej zoo: Cov dej zoo yog ntsuas feem ntau ntawm cov alkalinity, soluble ntsev (los yog conductivity) thiab cov as-ham hauv dej. Feem ntau, cov tsub zuj zuj ntawm soluble ntsev hauv dej, substrates, thiab chiv yuav tiv thaiv cov hauv paus kev loj hlob thiab ua rau cov hauv paus rot.
