Research ArticleOpen accessPhrase in the titleThe Resistance Evaluation of Dry Subtropics Brown Soils to Heavy Metal and Oil Contamination by Biological IndicatorsSergey Ilyich Kolesnikov, Natalya Aleksandrovna Petrova, Kamil Shagidullovich Kazeev et al.Contamination of brown calcareous soils with Cr, Cu, Ni, Pb and oil leads to deterioration of their biological properties. There is a reduction in activity of catalase and dehydrogenase, an abundance of Azotobacter genus bacteria, cellulolytic activity and the length of radish roots. As a rule, there is a direct relationship between the content of contaminant in the soil and … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 5 Aug 2016 · 7,888 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsPhysico-Сhemical Parameters of Humic Substances of Brown Coal and their Effect on the Growth of Phoenix dactyliferaDamilya Konysbaeva, Bolat Yermagambet, Zhanar Kassenova et al.The motivation for the study was the need to obtain data on the effect of humic acids isolated from brown coal on soil fertility and plant development. In our study, we conducted experiments with plants to isolate humic substances from brown coal and study its physicochemical properties and the effect of the resulting fraction on the growth of Phoenix dactylifera … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 21 Sep 2023 · 4,938 accessesView PDF Cite
