Soil health as a tool for sustainability, physical, chemical, and biological properties. Among the physical indicators, soil texture, aggregation, moisture, porosity, and bulk density have been extensively used, while among chemical indica¬tors soil pH, total C and N, mineral nutrients, organic matter, cation exchange capacity and biological ones such as microbial biomass C and N, biodiversity, soil enzymes, soil respira¬tion, etc., in addition to macro and meso-fauna play a major role in maintenance of soil health. Many human activities have caused desertification, loss of biodiversity, disruption of aggregates, loss of organic matter and nutrients. It is imperious to maintain soil health and productivity with increasing emphasis on reforestation and recovery of degraded areas through the use of organic amendments, reintroduction of plants, soil fauna and microorganisms.
