摘要

In a long-term field experiment, the rates of acidification and the losses of exchangeable Ca were established on a soddy-podzolic soil reclaimed by standard limestone (LPT) and dolomite (DPT) powder during 7 experimental years. Decreasing rates in the concentration of exchangeable Ca were -0.26 and -0.22 mmol (eq) 100 g(-1) of soil in the LPT and DPT treatments, respectively. Rates of changes in pH(KCI) were -0.120 and -0.135, respectively. A change in the concentration of exchangeable Ca by one unit led to a decrease in pH(KCI) in the LPT treatment by -0.257, and in the DPT one by -0.230 units. Empirical models described the changes in exchangeable Ca, pH(KCI), and hydrolytic acidity values throughout the entire study period. Regardless of the chemical composition of the calcareous material used, the soil lost its bases and was progressively acidified. However, the rate of the losses depended on the chemical composition of the amendant.
