Abstract

The aim of the study is to determine leaf nutrients, the number of ecological-trophic groups of microorganisms and the structure of microbial communities, microbial biomass ratios, and soil parameters in the upper soil horizons in the territory of the Sheki-Zagatala economic region from five representative hazelnut gardens located in the hazelnut producing villages of Katex, Darvazbina, Boyuktala (Balakan region), and Car, Galal (Zagatala region). Has been reported that soils with slightly acidic reactions are ideal for hazelnut cultivation. Hazelnut trees in Azerbaijan have sustainable and nutritious characteristics. They grow naturally without using any chemical fertilizers and pesticides. The soil fertility of the orchards is a key factor affecting the yield and quality of nuts. The number of microorganisms at 0-15 cm in spring was 10.059·103, 7.786·103 bacterias, 3.009·103 ray fungi, and 73·103 other microscopic fungi. In moderately eroded areas, the total number of microorganisms in spring was 8.927·103, bacterias 5.895·103, ray fungi 1.874·103, and other microscopic fungi 68 103. In non-eroded fertile soils, the number of microorganisms at a depth of 0-15 cm in autumn was 8.020·103 bacteria, 5.246·103 bacteria, 1.789·103 radiant fungi, and 5.8·103 microscopic fungi. The nitrogen (N), phosphorus (P), and potassium (K) contents of tree leaves in each variant ranged from 0.49-1.07, 0.16-0.36, and 0.58-1.49%, respectively, with average values of 0.73, 0.21, and 1.03%.

Abstract

The article shows climate data, soil moisture, humus and nitrogen content and other key indicators of the area (2022-2024). In this study we compare changes in the physicochemical properties of soils, the erosion factor, and humus and nitrogen reserves in natural ecosystems. The study of the variable importance of some soil parameters of forest ecosystems is considered relevant for Azerbaijani scientists. The highest erosion index was found in cultivated lands (0.270) and the lowest in protected forests (0.210). The results of this study showed that firewood cutting in natural forests, together with overgrazing, and forest to cultivated land conversion have caused significant soil degradation in the semi-arid region of Lerik. Overgrazing and exploitation of forest stands in natural forests, as well as the replacement of forests with cultivated lands, have significantly increased the density of sand (by 10.3-60.5%) and bulk density (4.1-7.16%), and have also significantly reduced the content of silt (2.34-8.56%), clay (2.36-10.5%), K (35.68-49.63%), P (15.58-29.38%), N (23.2-55.6%), and C (23.3-52.6%). There is little and rather contradictory information on the impact of grazing on soil properties. Research aimed at improving the use of pastures for grazing livestock in subtropical regions. No reliable changes in yield were found either at low grazing intensity (1/5, 1/10, 2/5) or at acceptable load levels (1/15, 2/10, 3/5) (13.7-14.6 t/ha). Grazing options 2/15, 3/10, 3/15 are excessive, leading to a decrease in yield by 0.43-3.07 t/ha, or 3.26-23.66%.
