Strategy of using protective forest stands to effectively disperse odors from livestock complexes (review)

Odor pollution of the environment is one of the most pressing air quality issues in intensive stock farming. To date, there are several strategies for combating unpleasant odors. To search for information, we used the following services: eLIBRARY, CyberLeninka, Scopus, Google Scholar, Web of Science, Google Academy, and Scholar.ru. The linguistic modeling of the subject field was based on keywords. Effective management of odors from livestock complexes can be achieved through the introduction of technology for the use of protective forest stands, i.e. artificially created arrays of trees and shrubs designed to protect agricultural lands and infrastructure from adverse effects, including odor load. In this case, protective forest stands act as barriers that reduce the speed and change the direction of the wind, which leads to effective dispersion of the odor. This occurs through physical interception and capture of gases and aerosol particles, dilution of concentrated odor from the downwind side, deposition of dust and other aerosols on the ground due to a decrease in wind speed, biological absorption (assimilation) of chemical components of the smell after interception. This helps to improve the aesthetic perception of livestock facilities and rural landscapes. The design of protective forest stands should correspond to the soil and climatic conditions of the region and the availability of planting material. In addition, it has a number of features emphasized in this work in relation to livestock facilities.
