abstract cadmium is one of the heavy metals with a considerable importance for its potential toxic effects on soil microbial activities and composition. although, the toxic effect of cadmium on soil microbial activities is somewhat well-known, but the extent to which cd affects soil biota depends largely on soil properties and conditions, particularly soil organic matter contents. thus, the aim...

enzymes are so crucial in the mineralization process of organic material. information of the soil enzymes activity is used in determining of the soil microbial properties and they are also important in soil health and quality. topographic attributes, soil properties and soil enzymes are associated together. hence, it is essential to know how these parameters affect on the soil enzymes activity....

protein-rich hydrolysate from feather waste was obtained using a mixed culture of selected thermophilic actinomycete strains, and was tested for possible application as soil amendment and biological control agent. for this purpose, a 4 months laboratory experiment was carried out using two types of urban soils (sofia, bulgaria): native park soil and anthropogenic soil. the effect of the obtain...

plants and soil microbes are the main sources of most enzymes available in the environment. it is, therefore, anticipated that any change in the growth of soil biota in response to salinity, may reduce the synthesis and production of extra- and intra- cellular enzymes. as a result, a reduction in the growth of plants and the activity of soil microbes in saline environments may lessen the level ...

Land uses has significant impact on soil biological properties that incessantly intimates the soil quality change and are assessed by soil microbial and biochemical indicators, as they are highly sensitive to change in environment. The purpose of this study was to investigate the impact of land use on soil enzyme activities and gene diversity in selected location of Northwestern Himalayas, Indi...

Enzymes are the vital activators in life processes, likewise in the soil they are known to play a substantial role in maintaining soil health and its environment. The enzymatic activity in the soil is mainly of microbial origin, being derived from intracellular, cell-associated or free enzymes. A unique balance of chemical, physical, and biological (including microbial especially enzyme activit...
