The role of bacteria in the soil Bacteria in the soil play key role in recycling matter in to useful nutrients which can be used by growing plants. This process of recycling matter in the soil by living organisms is called biogeochemical cycle. Bacteria are improving plants growth in other ways too‚ for example bacteria‚ such as Rhizobium‚ are in symbiotic relationship with the root system of some terrestrial plants. The most important elements‚ which allow terrestrial plants grow well‚ are

Coastal Erosion The beaches of North Carolina’s coastline face an ongoing threat: coastal erosion. Though mostly gradual and relatively unnoticeable over the course of a year or two‚ the rising sea level combined with a season of storms or hurricanes can cause anywhere from a few feet to hundreds of feet of this delicate shoreline being stripped away. Solutions are constantly being studied and discussed‚ but often‚ the solution to erosion can be just as damaging as erosion itself. While vacationers

These other forms of soil degradation‚ serious in themselves‚ usually contribute to accelerated soil erosion. Soil erosion is a naturally occurring process on all land. The agents of soil erosion are water and wind‚ each contributing a significant amount of soil loss each year in Ontario. Soil erosion may be

Throughout the world soil is constantly being eroded. There are three major principles that can cause soil to erode‚ leading to soil degradation. Over-cultivation‚ overgrazing‚ and deforestation have huge impacts on the degradation of the soil. There are‚ however‚ actions that can be taken to preserve or correct the conservation of soil. To further understand the prevention of degradation‚ we must fully comprehend the major causes of soil erosion. One major cause of soil erosion is over-cultivation
