Abstract: The aim of the research was to determine soil chemical properties in plots of agricultural crops and to evaluate the distribution of crop root biomass in plough horizon (in 0-20 cm in depth). Soil properties and plant root distribution specificities were evaluated in winter wheat (Triticum aestivum L.) - pea (Pisum sativum L.) - spring wheat (Triticum aestivum L.) plots where intensive technologies (traditional tillage, deep plowing and cultivation) have been applied. It has been determined that the agricultural technologies in the research are is maintained to stabilize crop and soil productivity. Although, intensive winter and summer wheat production, the main soil fertility properties (content of humus and total nitrogen) are maintained. Soil humus is significantly increasing (up to 2.4 %) in pea cropping plots. Meanwhile, the content of total nitrogen, is decreasing (up to 0.38 %) in plough horizon of winter wheat grown after the summer wheat. It is estimated that root biomass of crops is evidentially differing, winter and summer wheat root biomass was in average of 3 t DW ha-1, while in two times higher in pea cropping soil – in average 7 t of DW ha-1
