Application of Natural Humates for Remediating Contaminated Urban Soils and Stimulating Plant Growth

摘要

Long-term laboratory and microfield experiments have revealed the effective doses of humates for their use as detoxifiers of urban soils. The developed original technique allowed us to modify the commercial product Ekstra by fundamentally changing the ratio of amphiphilic fractions of humic substances. Field tests of new Ekstra growth showed its high efficacy as a plant growth stimulator and antistress preparation, which makes it possible to mitigate (or greatly reduce) the toxic effects of various pollutants on plants in contaminated areas.
