Abstract
The influence of prehistory (land-use history) and soil chemical properties on their allelotoxicity was studied on 12 soil samples of East-European plain with the use of 6 seed cultivars of spring wheat as well as seeds of barley, rye, and triticale. It is shown that despite differs ratio between the values of inhibition for different cultivars, their inhibition order on various soils preserves generally. Land use-history has a significant influence on soil allelotoxicity values: soil samples from territories of agricultural use have higher allelotoxicity in comparison with fallow areas. The experimental data show that crop rotations are not always able to reduce soil fatigue. This makes it necessary to assess the real soil fatigue (soil allelotoxicity) under the crop rotation. The material under consideration, methodological approaches and conclusions can be used in forestry.
