The objective of this work was to evaluate the contribution of liming to the leaching of C, N, P, Al, Fe, Mn, Cu and Zn compounds in soils. Samples (10 kg dry wt) of a virgin, sandy loam soil and a sandy soil in a rye field were limed with CaCO3 to neutralize 100% of the so-called hydrolytic acidity. They were then moistened to 100% maximum water-holding capacity and incubated for 4 months. During incubation, the soils were leached with 0.5 l deinoized water every week. The leachates were collected and their contents of dissolved substances, C, N, P, Al, Fe, Cu, Mn and Zn, were determined. The amounts of dissolved substances and leaching rates of elements investigated varied depending on soil history and liming. The amounts of dissolved substances and leaching losses of N and P were greater in the cultivated soil than in the displaced, virgin soil. C was more susceptible to leaching in the latter soil than in the former. Lime application significantly (P ≤ 0.05) increased the solubility of C and P in both soils and solubility of the metals in the virgin soil, whereas it decreased their solubility in the cultivated soil. Hence the liming of acid soils can enhance deficiences of certain nutrients in the soils. Further studies are required to determine whether in the long-term leaching could contribute to the contamination of aquifer under field conditions. Such knowledge is particularly important concerning N and P, which could trigger eutrophication. |
