Abstract

An effect of artificial humic substances extracted from active fraction of waste waters was assessed for soils and plants in laboratory conditions. Three laboratory experiments were conducted, with humic powders being added to soil in different portions. The results of experiment show that humic substances were physiologically active. Optimal portion of humic powders amendment is about 5 %. All the experiments show a decrease in main root length. An affect of optimal dose was stronger in soil with minimum of soil organic matter content.
