Due to polyfunctional significance of soil calcium as well as the application of common soil extract Mehlich III for some years the agrochemical practice feels the need to declare at least the "border" or the "treshold" extractable soil calcium concentration. On the basis of the regressional-statistical evaluation of a relative high populated (n = 952) soil data set having medium coarse structure assessing high significant relation Mehlich's III extractable calcium - exchangeable soil pH the border-line concentration for this Ca-species has been proposed. Taking into consideration both mentioned statistical relation, pedological and agrochemical aspects of soil calcium - aluminium reactions, some soil sorption parameters and several compatibility with previous soil extract Mehlich II the reasonable treshold Ca-level for medium coarse soils such as 1 400 mg Ca.kg sup(-1) it has been proposed.
