Silicon-Based Materials in Agriculture

Abstract

The more than 200-year history of studying the role and functions of silicon in the soil–plant system is shown. The main directions of research on silicon are given, including the study of the effect of silicon preparations on the mobility of heavy metals and on the resistance of plants to climatic changes. The silicon-mediated mechanisms of detoxification of cadmium-contaminated soils and reduction of cadmium accumulation by plants are generalized. There are 3 groups of silicon agrochemicals: silicon-containing soil meliorants, silicon fertilizers and biostimulators. The principles of the effect of these groups of agrochemicals on the soil–plant system are described.
