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%.

Abstract

The determination of soil salinization in the Shirvan Plain, considered the main agricultural zone of Azerbaijan, negatively affects the productivity of agricultural crops. Based on 10 m Sentinel-2 images on Google Earth Engine platforms and by examining SI1, green-red band normalized difference vegetation index (GRNDVI), green normalized difference vegetation index (GNDVI), normalized difference vegetation index (NDVI), and difference vegetation index of the environment (DVI), four remote sensing salinity monitoring index models, S1DI1, S1DI2, S1DI3, and S1DI4, were constructed to extract soil salinity information in the Shirvan Plain in combination with the measured electrical conductivity. The results show that the overall classification accuracy of S1DI1 (SI1-GRNDVI), S1DI2 (SI1-GNDVI), S1DI3 (SI1-NDVI), and S1DI4 (SI1-DVI) models for salinity monitoring are 82.35%, 83.10%, 81.96%, and 79.25%, respectively.

Abstract

The article provides a comprehensive analysis of modern trends and prospects for the use of solar batteries in various sectors of the economy and the agricultural sector. The purpose of this article is to analyze the possibility of energy saving for a private residential building in Gobustan using solar energy storage in a greenhouse extension and a heat pump to transfer heat to the heating system. The calculation showed that in the coldest month, December, the potential of solar thermal energy is 15-38% of the required heat demand, depending on the material used in the extension design. In March and April, excess heat is generated, which can be used for hot water supply needs. Thus, for an individual residential building, the use of solar heat accumulated in a greenhouse extension is relevant as an additional source of heat for the heating system. Surface density of solar radiation flux, W/m2: surface density of direct solar radiation flux: 1,680 (November), 1,530 (December), 1,870 (January), 2,730 (February), 3,270 (March), 3,180 (April); Surface density of diffuse solar radiation flux: 650 (November), 450 (December), 480 (January), 680 (February), 1180 (March), 1,830 (April).
