Abstract

Soils contain a large number of various living organisms such as nematodes, protozoa, fungi, algae, actinomycetes, bacteria and cyanobacteria, and all these living communities is an important element of the soil ecosystem. These organisms are involved in many important events such as nutrient cycling, decomposition of organic matter, soil carbon sequestration; modify soil physical structure and regulation of water regime. Biological soil degradation means that the significant reduction in population of microorganisms or absence in the soil due to changes in the biochemical processes occurring in the soil ecosystem. Environmental factors that temperature, moisture acidity as well as human activities such as agricultural practices have lead to soil biodegradation. Considering all these important functions of microorganisms in the soil that can be said, biological soil degradation is undesirable. To avoid this situation, primarily better understanding of the biological deterioration indicator in the soil, then it is necessary to analyze the factors which cause. In this review, based on earlier studies, indicators of soil biodegradation will be examined, the factors that cause it to be released and how it effects on soil activities and agricultural practices will be discussed.
