We investigated the changes in land use and NDVI in the Lipetsk region forthe period from 2001 to 2009 basingon remote sensing data of MODIS. It is established that the most significant reduction inareas is typical for young forests (areas where 5-10% of the area is occupied by trees with a height of not more than 5 m)that are passing into mature forest stage (land plots, 50-60% of the area of ...

The parameters of the biological and enzymatic activity of alluvial soils depending on the degree of hydromorphism and the type of land are determined. Alluvial marsh soils formed in the floodplain of the Kudma River in the territory of the Bogorodsky District of the Nizhny Novgorod Region, a significant part of which was drained in the 1960swith the drainage canal system, were studied. The bi ...

The differences insoil(ordinary chernozems) nutrient contents subjected to different tillage methods were revealed. The studies were performed in the Rostov region throughout different seasons in soils under various field crops in 28 fields where zero tillage and direct sowing were applied during 8 years. We also explored the control fields of the neighboring farms where the conventional tilla ...

Estimation of mutagenic and antimutagenic properties of nanostructured phosphorus – component of complex fertilizer

Degtyareva, I.A., Tatarstan Research and Development Inst. of Agrochemistry and Soil Science et al. [2019]

Mutations are the first significant step in the carcinogenesis process, therefore, mutagenicity tests should be widely used to detect mutagens/carcinogens. The article presents the material on the estimation of the nanostructured phosphorite effectson the mutation process in the Salmonella typhimurium strains. In this study, strains S. typhimurium TA1535, TA1538 were used without metabolic act ...
