  1. Biological activities in soil are widely recognized as playing a vital part in nutrient cycling and in developing and maintaining soil structure and contributing to ‘soil health’. Sustainable land-use, either in highly developed or subsistence economies requires that soil degradation ceases and that soil management practices are adopted to conserve and augment soil resources.

  3. Jun 15, 2004 · Thus addition of organic material to soil, and management practices that maintain soil organic matter (discussed in an earlier article in this series), will tend to increase the biological activity in soil. The type of organic matter added also will have some effect on the type of microbial community in the soil.

  4. This concerns soil properties related to the microbial and faunal activity in soil. These organisms include earthworms, nematodes, protozoa, fungi, bacteria and different arthropods. Soil biology plays a vital role in determining many soil characteristics, yet, being a relatively new science, much remains unknown about soil biology and about how the nature of soil is affected.

  6. Most biological activity takes place in the top 8 to 12 inches in the soil profile. The rhizosphere, or rooting zone, is an area of intense microbial activity and is integral to plant and soil relationships. Plant roots leak energy-rich carbon compounds, sugars and amino and organic acids called exudates.

  8. To be able to manage the soil sustainably, it is necessary to understand the roles that microbes perform in the soil and the numerous activities that they carry out. Soils of arid and semiarid regions are particularly challenging to manage, and a major issue is lower biological activities in such soils due to low organic matter contents.
