The microelement content in the soils of Mountainous Dagestan was studied by as. It is shown that total microelements content and its distribution in the soil profile depend on many factors, including the absolute height of the territory and the character of soil-forming rocks.
Dagestan is one of the Republics of Northern Caucasus. According to the relief it is divided into four main physic-geographical parts: Lowland, Foothill, Mountainous Dagestan (Alpine zone), this one is 1000 meters above the sea level. It contents 38,6% of total area of the republic [B. A. Akaev, Z. V. Ataev, B. S. Gadzhiev, and Z. Kh. Gadzhiev, Physical Geography of Dagestan (Vysshaya Shkola, Moscow, 1996) [in Russian]; S. U. Kerimkhanov, Dagestan Soils: Brief Characteriza¬tion and Use (Dagknigoizdat, Makhachkala, 1976) [in Russian]; Soil Resources of Dagestan. Their Conservation and Rational Use (Dagknigoizdat, Makhachkala, 1998) [in Russian]].
The concentration of Mn, Zn, B, I and the content of humus and pH of the soil for the main types of soils are determined. The regularities of the content and the distribution of Mn, Zn, B, I in the interested soils are detected. It is found that the soils of the Alpine Zone are enough enriched with Zinc and Boron, but inadequately supported with Manganese and Iodine.
The correlative connection between the content of Zinc, Boron and Humus are not identifiable. The dependence between the amount of Manganese, Zinc and pH of the soil is not found, and in case of Boron and Iodine a small dependence is available
