“…Soil quality is an important indicator of good crop yield in various land use contexts (Almeida et al, 2015). Doran and Parkin (1994) In recent years, soil biology has turned to assessing the degrading capacity of microorganisms by evaluating their enzyme activity (Fioretto et al, 2000). Microbial species release enzymes into the environment in order to degrade complex organic molecules into absorbable simple molecules (Almeida et al, 2015).…”

“…Decomposition rates are therefore linked to the enzymes that act directly on the main structural parts of plant material and can supply useful information on definite features of the microbial community and succession (Fioretto et al, 2000). This paper reviews the properties and roles of three enzymes -β-glucosidase, phosphatase and urease -as indicators of soil quality.…”

Soil is a fundamental resource and it is crucial to manage its quality in order to enhance agricultural productivity and environmental quality. Soil enzymes catalyze several biochemical reactions which result in the transformation of organic matter, and the release of inorganic nutrients for plant growth and nutrient cycling. Soil enzyme activities are useful biological soil quality indicators since they are operationally practical, very sensitive, integrative, easy to measure and more responsive to soil tillage and structure than other soil variables. There are several enzymes in soil, but those involved in hydrolases and the degradation of main litter components are used most often for evaluating soil quality. This paper reviews the roles of soil enzymes such as β-glucosidase, phosphatase and urease, as well as the implications of their activities for soil quality.

“…Y -hydrolytic acidity, S -sum of exchangeable bases, V -base saturation. (Fioretto et al 2000), pH (DeForest et al 2012), plant litter quality (Waldrop and Zak 2006) and C and nutrient availability can all influence enzyme activity. Soil temperature and moisture content changes are probably largely responsible for seasonal variation in enzymes activity (Boerner et al 2005).…”

The aim of this study was to assess the possibility of using biological and biochemical parameters in the evaluation of forest soil quality and changes caused by land use. The study attempted to determine a relationship between the enzymatic activity of soil, the number of earthworms and soil physico-chemical properties. The study was carried out in central Poland in adjoining Forest Districts (Przedbórz and Smardzewice). In soil samples taken from 12 research plots, basic physico-chemical properties, enzyme activity (dehydrogenase, urease) and density and biomass of earthworms were examined. Enzyme activity showed a large diversity within the forest site types studied. The correlations between the activity of the enzymes studied and C/N ratio indicated considerable importance of these enzymes in metabolism of essential elements of organic matter of forest soils. Urease and dehydrogenase activity and earthworm number showed susceptibility to soil pH, which confirmed relationships between enzyme activity and abundance of earthworms and soil pH in H 2 O and KCl.

Decomposition of lignocellulosic detritus at enzymatic level is the rate-limiting step during aquatic macrophyte decomposition. Assays were carried out to evaluate cellulase activity during decomposition of Utricularia breviscapa; the assays included the following C-sources: leachate, lignocellulosic matrix and integral detritus. The incubations comprised U. breviscapa C-sources added to Óleo lagoon (21º 36'S and 47º 49'W) water maintained in the dark under anaerobic condition at 15ºC, 20ºC, 25ºC and 30ºC. Cellulase activity were monitored during 180 days, with the activity showing a time evolution that depended on the temperature and type of detritus: (i) cellulase activity tended to occur earlier with increasing temperatures, but it was less intense than at lower temperatures, (ii) no activity was observed in incubations with leachate, (iii) cellulase activity was observed in the incubation with integral detritus and lignocellulosic matrix and (iv) higher cellulase activity was observed in the incubations with integral detritus at 15ºC (P < 0.05).
