In order to determine the effect of some neutralization acidity materials derived from natural sources (bentonite, zeolite, lifos, CaO, and MgO) on the change in the available phosphorus and potassium contents, a trial was set up on extremely acid soil to determine the manner of change in the nutrients concentrations in maize leaf and grain. The results obtained show that all ameliorative measures used affected the soil phosphorus and potassium contents increase, depending on the reduction of acidity and the mobile aluminium content, resulting also in a better uptake of the nutrients from the soil.
