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

A 2007 study finds that discharge of untreated sewage is the single most important cause for pollution of surface and ground water in India. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.[1] The majority of the government-owned sewage treatment plants remain closed most of the time due to improper

The Erosion Process1. Water. Erosion from water typically occurs in the following ways. a. Raindrop Splash and Sheet Erosion. The first step in the erosion process begins as raindrops impact the soil surface. Raindrops typically fall with a velocity of 20-30 feet per second. The energy of these impacts are sufficient to displace soil particles as high as two feet vertically. In addition‚ the impact of a rainfall on a bare soil can compact the upper layer of soil‚ creating a hard crust that

is a tool used in farming for initial cultivation of soil in preparation for sowing seed or planting.
