Soil acidity is largely controlled by the composition of ions on exchange sites on the colloidal fraction. The H+ cations are acidic by definition, and Al3+ cations are considered acidic because they react with H2O to produce … See more Of the several techniques available for determining pH, one that can be used easily in the field is the indicator strip method. This … See more To decide if a soil needs lime, you need to know only the pH, or the active acidity, of the soil solution. If the pH is less than or equal to 5.8, lime is generally recommended (the … See more Laboratory pH meters are more accurate than pH dyes and strips. The pH meter measures the hydrogen ion activity [H+] by measuring the electric potential across a thin, porous glass membrane at the base of the electrode. This … See more To decide how much lime a soil needs, you must determine the amount of reserve acidity in the soil. This reserve acidity is often called exchangeable acidity because it can be dissociated … See more
