Synthetic Fertilizer

Synthetic Fertilizer was applied to farmland is the epitome of unsustainable agriculture. In very short-sighted view, use that fertilizer is meaningful, because the plant requires nitrogen to grow. Crop season, therefore, are sucked out from the soil nitrogen, the exhausted after harvest. Traditional agricultural techniques, such as crop waste and the use of animal manure composting, nature will help available nitrogen cycle back into the soil. But at the beginning of the 20th century, German chemist development synthetic nitrates, which is used in the form of nitrogen plants. Initially, this kind of nitrate used in the manufacture of the bomb, instead of chemical fertilizer, but in the second world war, its use to agriculture. However, such a “quick fix” the price is very high, because help some crops nitrogen caused incalculable environmental damage.

Researchers from the university of Waterloo in Canada analyzed more than 2000 soil samples of the Mississippi valley. In the depth of the 10 inches and 3.2 feet, evidence of significant cumulative nitrogen was far below the soil surface This discovery has caused serious concern to the environment, even if stop using nitrogen. Dr Nandita Basu is sustainability and water ecological hydrology expert at the university of Waterloo, he told “newsweek” : “nitrogen is stored in the soil fact means that soon after the fertilizer, it could still is the source of nitrate levels longer application”. 2 newsweek to continue: “When fertilizer applied in farmland, some is absorbed by crops, some are dissolved in the water, some microbes into nitrogen. According to Basu, a part of soil organic matter in excess material itself is harmless. In fact, it makes the soil more fertile. But with the passage of time, the excessive nitrogen mineralization in the form of nitrate

Synthetic fertilizer destroyed the natural nitrogen in the soil, which means that farmers must use each year, more and more fertilizer to maintain their production. It is estimated that over the past 40 years, the nitrogen efficiency fell by two-thirds, while the per hectare (2.5 acres) of land use has increased seven times. 4 The U.S. department of agriculture (USDA) estimates that removal of nitrate in drinking water from the United States spends nearly $5 billion in 5, industry and agriculture industry basically be blocked.

Synthetic fertilizer is dangerous, you might not expect. For example, ammonium nitrate is an explosive chemicals. In 2013, a fire at a chemical fertilizer plant in western Texas killed 15 people, including 12 emergency personnel), another 160 were injured. Occupational safety and health administration (OSHA) are trying to implement strict chemicals for fertilizer retailers management and storage rules, but retailers association of agriculture, fertilizer institute, the American farm bureau federation and other institutions are fighting back. They are lobbying lawmakers stop OSHA application its safety standards, they said “will cause the agriculture retailers huge time and cost burden”, each facility cost up to $30000 (this seems to be a relatively small price, life) OSHA standards will apply to anhydrous ammonia, which is another type of nitrogen fertilizer, only a few years ago is the main element of the methyl mercury. White it is stored in the tank farm, make him
