County-Scale Spatial Distribution of Soil Enzyme Activities and Enzyme Activity Indices in Agricultural Land: Implications for Soil Quality Assessment
Here the spatial distribution of soil enzymatic properties in agricultural land was evaluated on a county-wide (567 km(2)) scale in Changwu, Shaanxi Province, China. The spatial variations in activities of five hydrolytic enzymes were examined using geostatistical methods. The relationships between soil enzyme activities and other soil properties were evaluated using both an integrated total en...

متن کاملKinetics of Soil L-Glutaminase Enzyme
L-Glutaminase enzyme was an important enzyme involved in the mineralization of amide forms of nitrogen in the soils. The characteristics of enzyme were determined by these kinetics. The two most remarkable properties of enzymes are their specificity and catalytic efficiency, and it is these properties that enzymes differ in their most strinkingly from simple catalysts. When it is possible to co...
متن کاملLead inhibition of enzyme synthesis in soil.
Addition of 2 mg of Pb2+/g of soil concident with or after amendment with starch or maltose resulted in 75 and 50% decreases in net synthesis of amylase and alpha-glucosidase, respectively. Invertase synthesis in sucrose-amended soil was transiently reduced after Pb2+ addition. Amylase activity was several times less sensitive to Pb2+ inhibition than was enzyme synthesis. In most cases, the rat...
