Opis:: In the study the physicochemical properties of selected municipal sewage sludge were compared using the reports on waste generation from the years 2007–2012 in the Mazovia voivodship. The selection was done on the basis of different methods of sludge processing and the number of equivalent inhabitants (NEJ) supported by sewage. Physical and chemical properties of municipal sewage sludge were significantly dependent on the method of purification and treatment methods. These sludges were characterized by a high content of organic matter and macronutrients. The amount of heavy metals (Pb, Cd, Cr, Cu, Ni, Hg and Zn) were within acceptable standards for municipal sewage sludge used in agriculture. Municipal sewage sludge treated by biological method with higher nutrients removal did not create bacteriological danger and were used in agriculture, generally to the cultivation of all agricultural products. Sewage sludge sanitized with lime and subjected to anaerobic digestion did not meet bacteriological standards, which eliminated their use in agriculture.

Opis:: The aim of the study was to assess the effect of bottom sediments on the selected properties of light soil as well as the content of trace elements in tested plants. The bottom sediments collected from the Besko reservoir were added to the soil in an amount of 5%, 10%, 30% and 50% of air-dried sediment, in relation to dry soil mass. The pot experiment was conducted on a light soil, with weak loamy sand grain size composition and slightly acid reaction, which was enriched with a supplement of bottom sediment. The test plant was a maize, Bora c.v. An applied bottom deposit revealed in its composition a considerable content of clay fractions, alkaline reaction and low total heavy metal content. Therefore, it may be applied as an admixture to light soils to improve their productivity. The addition of sediment to light soil resulted in the improvement of acidification in soil indicators: increased soil pH and reduced value of hydrolytic acidity, as well as improved sorption properties. A non-uniform effect of bottom sediment admixture on the content of trace elements in maize was determined. The sediment added to the soil increased the content of copper, nickel, chromium and, decreased the contents of zinc and cadmium in shoots. We did not find any excess of the permissible content of metals in plants used as animals forage in the maize biomass.

Opis:: Increase of sewage sludge production in Poland requires undertaking specific methods for their utilization and disposal. The reason is that sewage sludge, in addition to being rich in organic matter, and biogenic compounds such as nitrogen and phosphorus, which are beneficial from an agricultural point of view, also contain heavy metals, toxic organic pollutants such as persistent organic pollutants and polycyclic aromatic hydrocarbons, inorganic compounds such as silicates and clay, and pathogenic bacteria and other microbial contaminants. This implies problems with further use of such polluted sludge as fertilizer in agriculture. The aim of this paper is to analyze the possibilities and limitations of natural management of sewage sludge, taking into account their effects on the restoration and conservation of organic matter in the soil and the yielding of plants. In addition, the main methods of treatment of polluted sludge before introducing it into the environment are considered.
