erosion will provide if it is not managed quickly. Effects of Erosion The nitrogen cycle has a main component which begins with the nitrogen that is in the air. The nutrients that it provides the soil goes through a complex system that is similar to constant recycling. Nitrogen in the air turns into biological matter through bacteria and algae (this is also known as nitrogen fixation). Bacteria in the air mix with nitrogen and it eventually becomes

Manures The deficiency of plant nutrients and organic matter in the soil is made up by adding manures and fertilizers to the soil of crop-fields. Both manures and fertilizers are major sources of nutrients of plants‚ so they are used in crop production. Besides water CO2 and sunlight plants required no. of elements for their growth. These elements are known as nutrient. Plants get their elements from the salt of these elements present in the soil. But after repeated cultivation of plants soil become

of the overall process on the stoichiometery for growth and product formation (3). An aerobic fermentation process may be represented as: Carbon and energy source + Nitrogen source + O2 + other requirements Biomass + products + CO2 + H2O + heat This primarily involves consideration of the input of the carbon and nitrogen sources‚ minerals and oxygen and their conversion to cell biomass‚ metabolic products. Based on this information‚ it should be possible to calculate the minimum quantities

to reduce the harmful effects of nitrogen which gets mixed with water by natural hazard or else by man-made hazards. With the help of two types of bacteria like thiobascillus and rod shaped bacteria of bacillus species‚ we want to reduce the adverse effects of the dissolved nitrogen in the water bodies. HYPOTHESIS:- Nitrate-rich water containing denitrifying bacteria will exhibit a faster rate of reduction in nitrate levels. OBJECTIVE:- To denitrify nitrogen (Nitrate and nitrite) rich water.

Humans are affecting this cycle by over using phosphorus. Phosphorus is used to make fertilizers‚ animal’s feeds and detergents. The extensive amount of phosphorus reaching the oceans it’s causing severe water pollution known as eutrophication. Nitrogen is one

Study Most of the Filipinos earn a living through agriculture. Throughout the years‚ a lot of fertilizers were improvised‚ mostly for the comfort of the Filipino farmers. Human urine‚ for example‚ is a well-balanced nitrogen-rich quick-reacting liquid fertilizer. It contains nitrogen‚ potassium and phosphorus and other nutrients depending on the diet. The health risks associated with use of human urine in plant production are generally low‚ that is why it’s an adequate plant fertilizer. On another

British physicist named Lord Rayleigh asked chemists to explain the difference between the atomic weight of Nitrogen found in chemical compounds and the heavier‚ pure Nitrogen found in the atmosphere. Ramsay and Rayleigh were communicating daily with their results to solve their curiosity of the unknown gas. Rayleigh determined that a liter of pure Nitrogen weighs 1.2505 grams‚ but a liter of Nitrogen gas generated from air‚ by removing the Oxygen‚ Carbon Dioxide‚ and the water vapor‚ weighed 1.2572 grams

process was one of the competing industrial processes in the beginning of nitrogen based fertilizer production. It was developed by Norwegian industrialist and scientist Kristian Birkeland along with his business partner Sam Eyde in 1903‚ based on a method used by Henry Cavendish in 1784.[11] This process was used to fix atmospheric nitrogen (N2) into nitric acid (HNO3)‚ one of several chemical processes generally referred to as nitrogen fixation. The resultant nitric acid was then used as a source of nitrate (NO3-)
