Abstract
The widespread use of chemical fertilizers and plant protection products causes a serious imbalance in the environment and has an adverse effect on human health. Therefore, the study of the possibility of using safe bio-fertilizers is a very urgent task. This article provides an overview of research studies on the properties of chitosan that are of interest for use in agriculture. Chitosan, a natural compound that is made from the shells of marine organisms. Currently, a large number of studies are devoted to the study of the properties of chitosan, which protect crops from pathogens, as well as various abiotic stresses. It is established that chitosan effectively improves the physiological properties of plants, and also increases the shelf life of fruits. Chitosan is of interest as an additive to the soil as a nutrient that increases the efficiency of chemical fertilizers and does not affect the beneficial soil microbiota. In addition, chitosan increases the protective functions of plants at the genetic level.
