Opis:
The article deals with effect the use of organic (biohumus) and mineral (biochar) fertilizers based on the products of chicken vital activity on changing the fertility of technogenic sod-podzolic soils exposed to constant and unstable magnetic fields. The germination and growth dynamics of grasses and onions were investigated. The rational rate of introduction of the studied fertilizers into the technogenic soil is determined. Running (RMF) and direct (DMF) magnetic fields were applied in two ways: with fertilizers added and without fertilizers added. It has been established that the effect of preliminary magnetization of technogenic soil has a significant effect on lawn grass germination and the length of onion feathers, which are more than twice the height when exposed to the RMF, as compared with DMF. The effect of RMF on grass germination was also twice as high for DMF, when fertilizers were added. The DMF magnetization and biohumus helps to increase the grass sprout height by 10–20%. Onion sprouts were higher in two cases: DMF and biohumus; RMF and biochar. The influence of the factor of fertilizer type has a significant effect in 30–40% of cases, whilst at a spread rate of more than 5%, significant chemical activity of biochar negatively affects the germination of both grass and onion.

Opis:
The aim of this study was to analyze the dust load in St. Petersburg based on the measurements of dust levels in different areas of the city using a CEM DT-9880 portable dust particle counter. A uniform one-character bottom up zoning was performed to determine the parameters, and the dependencies of dust distribution on various factors were identified using the “Ecolog” software package. The zoning was based on more than 2.5 thousand measurements of dust levels. An effective and rational solution to the problem of increased aerotechnogenic load in different areas of the city through the use of modern technologies of hydro-dedusting of city roads with a dust-binding solution based on surfactants was proposed for increasing the adhesion ability of the solution to the standard roadbed.
