چکیده

This study was aimed at evaluating the effect of crop rotation and various tillage systems onthe chemical and biological properties of soil in the years 2013-2015. The first order factorincluded cropping systems: a) crop rotation (pea – winter wheat – spring wheat) and b)monoculture of winter wheat, whereas the second order factor were tillage systems:1) conventional (CT), 2) reduced (RT) and 3) No-tillage (NT). In the autumn season, in the CTsystem, shallow ploughing (at the depth of 10–12 cm) and pre-winter ploughing (25–30 cm)were applied for pea and spring wheat crops, whereas shallow ploughing and pre-sow ploughing(20–22 cm) were applied for winter wheat crop; in the RT system, only a cultivator was appliedfor spring wheat and pea crops as well as a cultivator and a tillage set for winter wheat; in theNT system glyphosate was applied on all plots as well as a cultivator and a tillage set were usedbefore winter wheat sowing. The study demonstrated that the soil sampled from plots with croprotation contained more organic C and available forms of P, K and Mg and that it wascharacterized by a higher activity of dehydrogenase, phosphatase and urease than the soilsampled from monoculture. In addition, it was characterized by a higher number of earthwormsthan the soil from monoculture. The RT and NT systems affected an increase in the contents oforganic C and total N and in the enzymatic activity of soil, compared to the CT system.
