Abstract
The article solves the urgent problem of developing a system for remote monitoring of the soil conditions of grape agrocenoses in the southern regions of Russia. It is shown that such monitoring is required to be carried out constantly because of the high anthropogenic load and critical decrease in soil fertility. Experimental studies showing the possibility of satellite remote monitoring of the soil conditions have been carried out, while the accuracy of determining the humus content in the soil when shooting with a camera in a laboratory and using satellite images obtained with multispectral equipment is no worse than 10-20 percent compared to chemical laboratory methods. For the experiment, 22 experimental plots, the condition of the soil on which was determined in the laboratory according to Tyurin and by shooting and processing images of a high-resolution digital camera, were laid. Synchronous data from the Russian satellite Kanopus-V were studied for the same areas. Analytical dependences of the humus content in the soil on the brightness level of the red spectral channel were obtained. The structure of the information system for remote satellite monitoring of the soil conditions in the region is proposed.
Highlights
Throughout the history of land use on our planet, one can see a pattern associated with changes in land use technologies, climate change, which leads to a constant loss of soil organic matter [1], the main representative of which is humus (85-90% of the total)
This study showed that the combined use of Landsat-8 and Sentinel-2 satellites makes it possible to use them effectively to monitor soil organic carbon (SOC) and the dynamics of changes in soil quality in extensive areas
An attempt to develop the foundations of a methodology for assessing the humus content of grape agrocenoses in the southern regions of Russia is made
Summary
Throughout the history of land use on our planet, one can see a pattern associated with changes in land use technologies, climate change, which leads to a constant loss of soil organic matter [1], the main representative of which is humus (85-90% of the total) It is the content of organic matter in the soil that is an integral indicator of its fertility [2]. High levels of organic carbon (humus, as the principal representative) in the soil determine the high yield of both agricultural production in general and viticulture All this determines the health of the soil cover of the grape agrocenosis [2]
