Impact of Agricultural Practices on Soil Health. When soil interacts with microbes, plants benefit from increased bioavailability and uptake of mineral nutrients (Glick et al., 1999). Soil micro-organisms take their quota of soil nutrients first and crops survive on the remaining soluble nutrients. Soil is one of the principal substrata of life on Earth, serving as a reservoir of water and nutrients, as a medium for the filtration and breakdown of injurious wastes, and as a participant in the cycling of carbon and other elements through the global ecosystem. ; Reddy, M.S. The restitution of micro-organisms that play an important role in the process of narrowing processes is more difficult (Schimel et al., 2005; et al., 2006). Following are examples of beneficials commonly found in cotton fields. Microbes that engage in mutualistic interactions with plant hosts can use their mutualistic exchange to transport nutrients and water (e.g., arbuscular mycorrhizal fungi, AMF), thereby increasing plant productivity. Each unit of carbon had a biomass and year of significance of approximately 1603 and 1664 respectively. Soils give a mechanical support to plants from which they extract nutrients. Gupta, G.; Parihar, S.S.; Ahirwar, N.K. The soil serves as a food web, providing essential nutrients to our forests and crops while also regulating Earths temperature and many of the greenhouse gases that contribute to climate change. soil, the biologically active, porous medium that has developed in the uppermost layer of Earth's crust.
