Vine plant chlorosis on unstructured calcareous soils and leaf Ca, Mg and K content
Excess calcium in expressly carbonate soils (up to 40 % CaO) in the Plešivica sub-region causes soil bicarbonates accumulation and ion antagonism, thereby disturbing uptake of nutrients, notably Mg and micronutrients. Deficit of some elements results in chlorosis and physiological disorders, which often depress yield and wine quality. Research results show significant differences in soil reaction and CaCO3 and CaO content between investigated soils of the Plešivica vine-growing region. Soil lime content influenced ion antagonism between Ca, Mg and K in vine plants. Magnesium uptake was probably depressed by Ca excess. Soil chemical properties were not the only reason for chlorosis occurrence. Chlorosis is a consequence of grapevine cultivation on inadequate rootstocks and also on unstructured soils of heavy mechanical composition.
