Application of carbonation lime on high pH soils in the Pannonian region of Austria
Abstract
The effect on yield as well as on chemical and physical soil conditions of elevated applications over several years of carbonation lime (0, 75, 150 and 300 t/ha) was investigated in soils of high pH value . Neither yields nor contents of the most import macro- and micronutrients were effected by the rising quanties of carbonation lime. The pH of the topsoil was raised slightly only in the case of a natural lime content of less than 0,5 %. The levels of phosphorus and exchangeable magnesium in the soil increased . With applications of carbonation lime exeeding 150 t/ha, the amounts of iron and manganese available to plants declined. Levels of copper, zinc and boron remained unchanged. Application of carbonation lime improved hydraulic conductivity and penetrability, and there was greator root development. At the conventional level of carbonation lime application of about 10 t/ha per crop rotation , no detrimental effected on plant growth or harvested productt quality is to be expecccted even in soils of high lime content.
