Annotation

The article presents results of the research about the content of mobile forms of some microelements in the soil of arable lands in Drohobych, Zhovkva and Zolochiv districts of Lviv region. The goal of the research was to study the actual content of some microelements (Cu, Mn, Zn, Co, В), to determine the figure of deviation of the tested mobile forms of microelements from the boundary admissible concentration (BAC).

It is determined that arable lands in Drohobych district belong to forest-meadow Pre-Carpathian (65 % of the territory) and forest-meadow mountainous Carpathian (35 % of the territory) natural zones. Turf-podzolic, turf and black land-meadow soils are prevailing kinds of soil at farms.

In Zhovkva district, land uses are located in the Forest-Polissia (80 % of the territory) and Forest-Steppe (20 % of the territory) natural zones. Arable lands of that district are mainly presented by such soils as turf-podzolic, turf, black land-meadow and meadow, light-gray and gray podzolic, black land carbonate and turf-carbonate.

The territory of land uses in Zolochiv district belongs to the Forest-Steppe (100 % of the territory) natural zone. In the structure of soil top layer of the area, the most common kinds include black land carbonate and turf-carbonate, dark-gray and black land-podzolic and turf soils.

It is confirmed that degree of supply with Borium is high, with manganese – an increased, copper and cobalt – a very high, zinc – a low one.

The obtained data will create a basis for the further analysis concerning supply of soil with microelements, which are necessary for appropriate growth and development of plants. It will secure production of agricultural products of high quality.

Key words

arable lands, soil, microelements, Borium, manganese, copper, cobalt, zinc
