The article presents the results of a study of polyethylene samples exposed to natural climatic factors for 18 months by Raman spectroscopy. The spectra were obtained at different depths from the sample surface and it was shown that the stages of material degradation depending on the depth have different degrees. An estimate of the degree of degradation from depth is given, according to which the material undergoes structural changes most intensively at a distance of up to 40 µm from the surface. At depths greater 80–100 µm, structural changes in the material are not detected.

The article is devoted to the study of the results of monitoring the indicators of soil nutrition of LLC «Plodovoye» of the Yeisk district of the Krasnodar Territory. The article presents the data of the results of the agrochemical survey of agricultural soils of the enterprise, analyzes the data obtained by comparing them with the results of the previous round of soil survey, draws appropriate conclusions and prepares recommendations for improving the indicators of soil productivity of the enterprise, as well as suggests ways to combat soil degradation of the enterprise.
