MODERN RESEARCH OF SOILS UNDER CORYLUS AVELLANA L. IN BALAKAN AND ZAQATALA REGIONS

Abstract

The article deals with the current state of soil formation products and migration of substances under Corylus avellana L. At the beginning of November, the amount of completely dry mass was 25.4 s/ha. During the vegetation period, the underground phytomass varies in the range of 115-221 s/ha in different senoses. Fairly high values of chemicals were characteristic of the 8-10 cm layer, the amount varying between 78-270 mg/l dry residue. Above-ground phytomass is 1599 kg-ha, and root biomass is 2018 kg-ha. Hazelnut varieties grown in Balakan region are Butternut, White lombard, Atababa, Ashrafi, Mold, Arzu, Golden Walnut, Cherkassy, Curly, Sachag, Azeri, Ataulla, Barli, Ghaffarash, Nasimi, Topgara, Parzivan sycamore. In recent years, 20-25 thousand tons of Corylus avellana L. have been grown. The prevalence of Aspergillus niger fungus is 60.0% in soils formed under Corylus avellana L., 56.4% in irrigated soils, and 50.6% in dry soils. Proteobacteria, Actinobacteria, Acidobacteria, Firmicutes, Chloroflexi dominate. Verrucomicrobia, Planctomycetes, Bacteroidetes, Nitrospirae, Gemmatimonadaletes are relatively rare
