چکیده
Wastewater sludge from municipal wastewater treatment plants in Nizhny Novgorod and soils based on them, prepared with different ratios of sludge, sawdust peat, have been investigated. Sewage sludge-based contain plant nutrients are suitable for use as fertilizing materials green building. Under the conditions a three-year lysimetric experiment cereal lawn grasses, significant efficiency organic was noted comparison traditional soils. The maintenance regime revealed differences mixtures terms effect productivity phytocenosis. Use sewage containing large amounts heavy metals one soil components undoubtedly leads to increase amount these toxic elements whole.
