摘要
Addition of marl (CaCO3) and/or manure to an acid soil in pots caused 'lime-induced' chlorosis in Pinus radiata seedlings, especially after excessive irrigation for 15 days. Chlorotic symptoms and their intensity were found to be related more to soil moisture and to the HCO3- concentrations, than to percentage of free CaCO3, in the soil mixtures. Comparative chemical analysis showed lower total Fe and Mn concentrations and higher concentrations of cations and organic anions in the needles of seedlings with chlorotic symptoms than in the needles of healthy ones. © 1979 Martinus Nijhoff.
