“…Similarly, Lee et al (2007) reported variable responses of seven hydrolytic enzymes to storage of three soils differing markedly in texture, but with similar pH (5.4e6.1) and (low) organic matter contents. In the current study we did not find major differences in the response of four hydrolytic enzymes to soil storage, although it is possible that differences may be greater for other soils depending on the physical protection offered by the soil matrix, based on properties such as the particle-size or aggregate size distribution (e.g., Marx et al, 2005;Muruganandam et al, 2009).…”

“…It is the driving force in the decomposition of carbohydrates in soils. The resulting hydrolysis products (sugars) are important energy sources for microorganisms in soils (Eivazi & Tabatabai, 1988;Marx et al, 2005).…”

“…Several studies have also shown that changes in soil moisture content have significant effects on the kinetic parameters of soil hydrolases (Burns, 1978;Ladd, 1985;Boyd & Mortland, 1990). Marx et al (2005) showed that β-glucosidase followed simple Michaelis-Menten kinetics in all soil particle-size fractions. However, little information is available about the effect of environmental temperature and moisture on the kinetic properties of this enzyme in soils.…”

Soil β-glucosidase participates in the final step of cellulose biodegradation. It is significant in the soil C cycle and is used as an indicator of the biological fertility of soil. However, the response of its kinetic parameters to environmental temperature and moisture regimes is not well understood. This study tested the β-glucosidase response in the main agricultural soils (black soil, albic soil, brown soil, and cinnamon soil) of Northeast China. Incubation tests were conducted to measure the kinetic parameters Km, Vmax or Vmax/Km of soil β-glucosidase at environmental temperatures of 10, 20 and 30 ºC and at 10, 20 and 30 % soil moisture content. The insensitive response of the kinetic parameters to temperature changes indicates that soil β-glucosidase was present primarily in immobilized form. The significant response of the kinetic parameters of soil β-glucosidase to soil moisture rather than to environmental temperatures suggests that the catalytic ability of soil β-glucosidase was sensitive to changing soil moisture regimes.

“…The results are in confirmation with data obtained by other authors. Marx et al (2005) showed that activities of hydrolases studied positively correlated with organic carbon content in grassland silty clay loam soil. Similar correlations were reported by Park et al (2014) and Yin et al (2014), as cited before.…”

“…Authors showed that enzyme activities in particle-size fractions were mostly affected by the type of tillage. According to the study of Marx et al (2005) phosphatase had the highest absolute activity in the clay-size fraction of grassland soil.…”

Article Info Received : 14.03.2016 Accepted : 06.06.2016 Soil erosion is a serious environmental problem and a threat to the sustainable agriculture production. Little information is available on enzyme activities of eroded soils in Bulgaria, especially on their relations to the degree of erosion and soil properties. In this work, slightly, moderately and severely eroded Chromic Luvisols under different land use (pasture, crop field and virgin) were studied. Enzyme activities (invertase, catalase and phosphatase), total nitrogen, total carbon, available phosphorus contents and soil particle distribution were determined and possible relations between them were examined. Data showed that enzyme activities tended to lower with increasing the degree of erosion. This was better pronounced for invertase and phosphatase in pasture and virgin soils. Depending on land use, all enzyme activities decreased in the order pasture > virgin > crop field soils, showing positive impact of soil cover and negative effect of cultivation practices. Soil invertase and phosphatase activities were in close relations with soil carbon content. The activities of catalase and phosphatase correlated positively with soil clay. Invertase only was in positive relation with soil silt and in negative relation with the sand content. Data obtained are intended to contribute to development of biological indicators of eroded soils.
