Modificarea proprietăților fizice ale solului sub impact antropic [Articol]

Abstract

The paper presents investigations concerning the carbonatic chernozem physical changes under anthropic impact (soil tillage). There were chosen some agroecosystems from long-term crop rotation, single-crop systems, weedfree fallow (55 years), fallow (55 years). The researches has shown that, with anthropic-impact amplification (soil tillage), physical soil properties such as structure, plasticity, adherence are getting worse. The best physical soil properties were established at fallow (55 years) and the worst at weed-free-fallow (55 years), the other studied agroecosystems takes an intermediate position between these two extremes.
