Abstract: 

The effect of various tillage practices on the distribution of available phosphate and potassium was studied with 4 different arable soils, a Luvic Phaeozem derived from loess, an Eutric Cambisol, a Gleyic Luvisol derived from schist and a Dystric Fluvisol. Available P and K were determined by the CAL-method which is an extraction with a solution of Ca lactate + Ca acetate (pH 4.1).

Reduced tillage (no-tillage and 2 types of cultivators) showed a tendency of P accumulation in the upper soil layer (0 cm to 10 cm) as compared with the plough treatment. This tendency, however, was only significant on the sandy soil. On the alluvial soil no-tillage the 2 types of cultivators brought about a decrease of available P in the deeper soil layers (15 cm to 25 cm, 30 cm to 60 cm). Reduced tillage increased the available K in the upper layer of the sandy soil significantly as compared with the plough treatment. On the other soils this tendency was less clear. It thus appears that the various tillage practices had the strongest impact on the vertical P and K distribution of the sandy soil.
