Purpose. The soil elementary processes (SEP) in the inundated landscapes of Uda river in Kharkiv’s range are investigated. Methods. Complex field, chemical analytical techniques and methods of data processing (including interpolation methods, clustering, and so on). Results. With the method of expert’s estimations the intensity of the soil elementary processes is gave to assessment to the territory of the study. The acid-alkaline characteristics of soil genetic horizons of inundated landscapes of Uda river in Kharkiv’s range are evaluated. The presence of natural height valuable sorption and chemisorption lateral acid-alkaline geochemical barrier in the ​​research area is suggested. Conclusions. The most common and severe elementary processes of soil formation floodplain landscapes p. Uda within Kharkiv is humus-ilyuvialny and clay-ilyuvialny processes related to illuvial accumulation processes, ie, dominated by the processes of accumulation of matter and energy, which is indicative of the presence of natural geochemical barrier, due to the peculiarities of the relief and the composition of the parent rocks.

There are the results of investigation of the influence of the form of organic fertilizers on biometrics vegeta-bles (tomatoes for example) and the behavior of metals in the soil. The study was conducted in Kharkiv and Cherkasy regions. Оn experimental plots where made fertilizers, was an increase in the height and thickness of the tomato plant stems at the base of the bush, and the number of inflorescences . It was determined that the soil has decreased the amount determined by the mobile forms of metals. It was determined that the most «environmentally safe» fertilizer include Scots pine litter and worm castings , where the content of mobile forms of metals smallest .
