Abstract
The influence of degree of grinding on the apparent chemical composition was studied in 11 different soils (fraction aqua regia extractions, were hardly influenced by the grinding procedure. The availability of some nutrients like Na, K, and Mg, estimated by weak extractants, was significantly influenced by the degree of grinding in some soils. Potassium and Mg concentrations were higher in the finer fractions. For P, sometimes an increase, but also in some soils a decrease was found. The variance of the analytical results was in most soils and for most estimated parameters not influenced by the degree of grinding.
