Abstract:

Soil erosion is the most important environmental problem for rural lands. It is well known, that soil is one of the important and limited strategic natural resource for ensuring the economic and food security of the country. At the same time, the soil is subject to degradation from erosion processes. Soil erosion is a major environmental threat to the sustainability and productivity of agriculture and socio-economic sustainable development of the country. According to various researchers, the soil conditioners (soil improvers) are one of the methods to prevent and reduce soil erosion. The purpose of this scientific review was the study of data in use of soil conditioners to control and reduce water erosion in agriculture. During this study, a review of the literature aimed on the problem of using of soil ameliorants to combat soil erosion was carried out. The retrospective of the literature search was within 44 years (1976–2020). Soil conditioners are used to reduce surface runoff and splash erosion; they are increase infiltration and stabilize soil aggregates. Soil conditioners are used in liquid or dry forms. The data on the concentration of soil conditioners recommended by various scientists are given.
