Analysis of patent information in the field of soil reclamation

Currently, assessing trends in the development of science and technology is an urgent task. The article contains an analysis of the patent landscape in the field of soil reclamation for the period 2020-2025 in Russia. The exploratory method was used to process the information. We found that 76% of inventions are unidirectional soil reclamation. Integrated reclamation accounts for 24% of all inventions. Water, chemical and technical types of reclamation prevail among the inventions for unidirectional change in soil properties. Chemical and/or plant soil reclamations are used in 49% of inventions of integrated regulation of soil properties. Organizations Russian Research Institute for Land Reclamation, Federal Scientific Center for Hydraulic Engineering and Land Reclamation named after A.N.
