摘要: The influence of degree grinding on the apparent chemical composition was studied in 11 different soils (fraction <2 mm) from Netherlands. Representative subportions were crushed or ground till they just passed a plastic sieve 1.0, 0.5, 0.25, and 0.15 mm, respectively. All samples analyzed triplicate for soil parameters total bioavailability concentrations several inorganic constituents. concentrations, mainly aqua regia extractions, hardly influenced by procedure. availability some nutrients like Na, K, Mg, estimated weak extractants, significantly soils. Potassium Mg higher finer fractions. For P, sometimes an increase, but also decrease found. variance analytical results most not grinding.
