Structure, microbial metabolism and potentially mineralizable nitrogen pools in organically and conventionally farmed clay soils Soil physical, soil chemical and biological studies were carried out on two differently cultivated clay soils. One soil, under organic farming system (TNL), was not ploughed for the last 14 years, the 0–10 cm layer was tilled by a rotowator system. The other soil was tilled conventionally and was ploughed down to 22 cm (TKL). For comparison the topsoil of a pasture was investigated. The saturated hydraulic conductivity (depicted as frequency distribution from kt values) was very high in the TNL soil and in the pasture soil. The TKL soil showed a lower conductivity and pore continuity than the other soils, especially in the layer of 0–10 cm (Aprhonzon). Aggregate stability (measured as total settlement) was highest in the pasture soil, followed by the 10–20 cm layer of TKL soil. The small fragments of TNL soil resulted in a decline of the aggregate stability. Dehydrogenase activity was similar in the TNL soil and the pasture, and lower in the TKL soil. Potentially mineralizable nitrogen showed the same trend as dehydrogenase activity. Soil respiration was higher in the TKL soil than in the TNL soil. This was attributed to higher amounts of microbial available carbon probably because of the presence of undecomposed crop residues in the TKL soil.
