The Importance Of The Nitrogen Cycle

The study authors stress that the findings don't mean that farm merchandise cause Parkinson's disease, they only show a link between the 2. Depression Opting for low-fat farm instead of full-fat farm reduces the chance of depression, per academician. Ryoichi Nagatomi, of Tohoku University in Japan, and team. Adults World Health Organization consumed milk and yoghurt between one and 4 times per week were less doubtless to expertise depression symptoms than people who reportable no farm consumption. Brain health People with higher intakes of farm merchandise are shown to get considerably higher on memory and brain perform tests than people World Health Organization drink very little or no

Nitrogen is a major component of the atmosphere, but an essential nutrient in short supply to living organisms and is often the most limiting nutrient for plant growth but can also be found in organic matter in soil and the oceans. It is used to make organic molecules such as amino acids (and thus proteins and nucleic acids) for living organisms. Animals require nitrogen for metabolism, growth, and reproduction and get it by consuming nitrogen-containing molecules in organic matter of both living and dead sources. (Pidwirny 2008) The nitrogen cycle can be summarized as follows; Nitrogen in the air (70%) gets converted into a useful form by nitrogen-fixing (conversion of nitrogen into nitrates) bacteria in the soil. This is assimilated by plants and animals.

‘Agricultural pollution’ is an umbrella term used to describe the sources of wastes, emissions, and discharges arising from farming activities, and includes, but is not limited to: livestock and livestock manure, poultry litter, chemical fertilizers, chemical pesticides, sediment, agro-chemicals, organic containments, heavy metals, and general farm procedures. This form of pollution greatly affects bodies of water across the globe. According to 2015 estimates from the Bay Program, “agriculture contributes 42 percent of the nitrogen, 55 percent of the phosphorus and 60 percent of the sediment entering the Bay,” making it the largest source of sediment and nutrient pollution in the Chesapeake Bay. Nitrogen and phosphorus are the two most common

LITERATURE REVIEW Inorganic fertilizers provide rapid nutrition and give plants with the nutrients needed to grow healthy and strong. Inorganic fertilizer, also called as synthetic fertilizer, is manufactured artificially and contains minerals or synthetic chemicals and it is which help a plant to grow faster. Effective use of Inorganic Fertilizers Effectiveness in using these chemicals has good and bad effects on the environment especially on the health of a human being. Fertilizer has turn into essential to modern agriculture to feed the growing population. Use of fertilizers, especially, the chemical fertilizers has brought in blessings on humanity, which helped contain hunger and death in changed corners of the world.

However, nitrogen is not only associated with gas. Nitrogen turns to a liquid state when exposed to extremely low temperature (-210 C). Liquid nitrogen has a density of 0.807 g/ml. Nitrogen is widely used in the chemical industry as well as in our everyday daily lives. In the chemical industry, nitrogen is needed to make fertilizers, nitric acid, nylon, dyes and explosives.

Introduction Aim: To compare the effectiveness of compost and earthworms on the germination and yield of a spinach crop. Motivation: Fertilisers are mixture of chemicals that add nutrients to the soil to establish better yielding crops (Berger, 2013). Though these products have proved to provide many beneficial aspects to the agricultural sector, they have many negative environmental consequences. Fertilisers contain many substances, including mostly potassium, phosphorus, sulphur, calcium, magnesium and nitrogen. These substances, when they accumulate in the soil, can have harmful side effects on the environment and subsequently on the productivity of crops (Vimpany and Lines-Kelly, 2004).

Animal agriculture is creating devastating effects on the environment, and in order to combat these threats, we must embrace safer, alternative forms of food production. Our modern use of animal agriculture is one of the biggest threats to our environment. Due to the massive amounts of carbon dioxide, methane, and nitrous oxide emissions, animal agriculture

Fertilizers are only used if the seed is to be planted on a soil that is nutrient deficient. According to Cosper (1951), the three main plant foods, namely nitrogen, potassium and phosphorus, are always present in commercial fertilizers and are sometimes called balanced fertilizers. One difference in organic and conventional farming is the use of humus. Humus is an organic substance that has decomposing vegetables and manure. It provides extra nutrients for the plant’s growth and life cycle.

it is use in feed supplement farming that helps to promote animal growth as an alternative antibiotics. Bacillus subtilis can produce a variety of antimicrobial to compete other microorganisms by either killing them or reducing their growth rate. And subtilis also produce JAA that can be used against various crop diseases which can decrease significantly the growth and productivity of the crops (Wertheim et., al,2o14). Pseudomonas aeruginosa normally inhabits the soil and surfaces aqueous environment. This pathogen can tolerate a low oxygen conditions and it can survive in low levels of nutrients and temperatures.

The research also showed that the GM foods have high nutrients and contain more minerals and vitamins compared to the traditional crops. Key et (2008) GM technology offers a way to alleviate some of these problems by engineering plants to express additional products that can combat malnutrition. The authors trying to say that genetically modified crops can produce more nutrients that are needed by the human body. Whitman (200) stated that genetically modified crops are drought/salinity tolerant. These plants can withstand long periods of drought or
