“…Our findings also agree with those of Vance (1996) and Chander et al (2001). The former found that the changes in MBC were correlated with the granulometry of the WA added to soil, and that the addition of fine WA granulometry immediately affected the system.…”

-Wood ash production is increasing due to the increasing use of wood as a sustainable fuel. Wood ash can be recycled in crop soils as a source of nutrients and as a liming agent to correct soil acidity. However, the effect of wood ash on soil quality is poorly known. Here we studied the effect of addition of wood ash at 5 and 20 t ha -1 on microbial and biochemical properties in samples from the 0-30 cm surface of three neutral and two alkaline agricultural soils. The samples were incubated for one year at 25 °C and 60% water-holding capacity. The soil microbiological biomass (microbial biomass C and N), general microbial activity using fluorescein diacetate hydrolysis, and alkaline phosphatase, arylsulphatase, catalase and o-diphenoloxidase activities were determined periodically together with pH and electrical conductivity. Increases in microbial biomass C and fluorescein diacetate hydrolysis occurred at the lower wood-ash dose, whereas microbial biomass C decreased at the higher wood-ash dose over the entire period, and the fluorescein diacetate hydrolysis after 4 months. The microbial C/N ratios of treated samples were significantly different with respect to that of the control, suggesting changes in the structure of the microbial communities. The changes in microbial biomass and microbial activity were related to the increases in pH, which induce the development of bacteria to the detriment of fungi, to the electrical conductivity, and to the nutrient levels after wood-ash addition. Alkaline phosphatase and arylsulphatase activities were weakly inhibited at 20 t ha -1 , and catalase activity was stimulated in the neutral samples and inhibited in the alkaline samples. The highest o-diphenoloxidase activity observed throughout in all of the treated samples may suggest a decrease in the mineralisation process. Our findings reveal that the soil biochemical parameters investigated are significantly affected only in some cases at 20 t ha -1

Contamination of soils by heavy metals is a severe problem because of disturbances caused in the functioning of the soil and the whole ecosystem. Therefore, the aim of our research was to determine the influence of contamination of soil by zinc, copper, nickel, cadmium, and lead on the activity of arylsulfatase. A novel element of the study is a comparison of the response of arylsulfatase to five heavy metals in three soils with two pH ranges: 7.0 and 5.5. The studies were carried out under laboratory conditions. The soils (loamy sand, sandy loam, sandy clay loam), with pH 7.0 and 5.5 and contaminated with zinc, copper, nickel, cadmium, and lead were incubated for 30, 60, and 120 days. After each period, the activity of arylsulfatase was determined. Base on the activity of arylsulfatase, a resistance index of arylsulfatase (RS) to contamination with heavy metals was calculated. The highest activity of arylsulfatase was found in sandy clay loam, while the lowest was found in loamy sand. A significant correlation between the resistance of the enzyme and the level of contamination of the soil with heavy metals was proved. Arylsulfatase was most sensitive to the effects of zinc, copper, and nickel, while cadmium exerted a somewhat weaker influence and lead the least. The enzyme exhibited a higher resistance to the influence of heavy metals in neutral soils than in acidic soils. The toxic effect of heavy metals can be ordered as follows: zinc > copper > nickel > lead > cadmium.

“…The trace elements contaminating the soil inhibit the activity of microorganisms living in it, thereby contributing to a reduction in their vital functionsdecomposition and transformation of organic substances (Becker et al 2006, Hander et al 2012, OciepaKubicka and Ociepa 2012. The limited microbial activity in the rhizosphere has a negative effect on plants, inhibiting their normal growth and adversely affecting their resistance (Meers et al 2007).…”

This article presents the results of a study on the content of selected trace metals (Pb, Zn, Cu, Cd) in soils near the main traffic routes of the Warsaw agglomeration. The aim of the study was to determine the extent of soil contamination with trace metals at different distances from the road (by the side the road and 50 meters away from the road). In the soil 50 m away from the road in £omianki 'low contamination' was found for zinc and 'elevated content' for copper according to the IUNG guidelines, but the amounts of the trace elements were not found to exceed the permissible levels as specified in the Regulation of the Minister for the Environment of 1 September 2016.
