background: the present study investigated the impact of land use on health risks (cancerous and non-cancerous) of heavy metals in soil along the hemmat highway of tehran, iran. materials and methods: a total of 28 soil samples were collected in august 2014 from the roadside soil of the hemmat highway. the collected samples were air-dried and digested, and then, analyzed for heavy metals using ...

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...

Soil is a living system and has to be managed as such in agriculture to improve sustainability. Soil health refers to the biological, chemical and physical features of soil that are essential to long-term sustainable agricultural productivity with minimal environmental impact. Thus, soil health provides a overall picture of soil functionality. Soil provides the habitats for a wide range of livi...

What is soil health? The objective of this presentation is to present information on the types of measurements of soil biological properties that might be useful as bio-indicators of soil health. First, however, it is necessary to discuss what soil health means. Scientists, farmers and land managers have long known that there is more to the productive capacity of soil than what can be predicted...

While soil quality encompasses physical and chemical besides biological characteristics, soil health is primarily an ecological characteristic. Ecosystem health has been defined in terms of ecosystem stability and resilience in response to a disturbance or stress. We therefore, suggest that indicators for soil health could be found by monitoring responses of the soil microbial community to the ...

Soil health refers to the biological, chemical, and physical features of soil that are essential to long-term, sustainable agricultural productivity with minimal environmental impact. Thus, soil health provides an overall picture of soil functionality. Although it cannot be measured directly, soil health can be inferred by measuring specific soil properties (e.g. organic matter content) and by ...

Soil quality and health are terms describing similar concepts, but the latter appeals to farmers and crop consultants as part of a holistic approach to soil management. We regard soil health as the integration and optimization of the physical, biological and chemical aspects of soils for improved productivity in an economic and sustainable manner. This paper describes the process used for the s...
