Using spectral indices for interpretation of plant residues under different tillage systems

Intensification of agriculture leads to development and implementation of new soil conservation technologies that reduce degradation processes, as well as the development of methods for monitoring and controlling these technologies. Spectral indexes method as one of the methods of remote sensing is one of the most modern methods for solving this problem. This research was conducted on three production fields located in the territory of the Budenovsky district of the Stavropol territory, where plowing with the layer turnover and no-till technology were used. Aim of this research is analysis of the possibility of using 8 spectral indices to identify different types of soil cultivation. The study found that the most informative differences between tillage systems are provided by NDTI, STI and NDI7, which use the SWIR 2 spectral range for calculations. In addition, the classification of objects based on these indexes by the K-means method gives the highest accuracy.
