Where is fertilizer found

Early writings show that they used manure from different animals based on the type of crop they were growing. Other early fertilizers included vegetative waste, seashells, and waste from manufacturing processes. In the early 17th century, people began to perform organized research into fertilizer use. Francis Bacon wrote about the benefits of adding saltpeter to farmland. Scientist Johann Glauber also researched using saltpeter as a fertilizer and created the first complete mineral fertilizer.

His formula included saltpeter, nitrogen, phosphoric acid, lime, and potash. Eventually, scientists learned more about the chemical requirements of plants.

Scientist Justus von Liebig showed that plants need nitrogen and phosphorous to grow. Discoveries such as this led to further refined fertilizer formulas. In , Sir John Lawes filed for a patent for a process to produce superphosphate using phosphate rock and sulfuric acid. He then opened the first fertilizer factory, marking the beginning of the synthetic fertilizer industry.

He also founded the first agricultural research station, Rothamsted Experimental Station. Along with Sir Henry Gilbert, Lawes continued to study fertilizers extensively.

After World War I, facilities that manufactured ammonia and synthetic nitrates for use in explosives converted to fertilizer factories, giving the artificial fertilizer industry a substantial boost. The fertilizer industry continues to progress. Current research often focuses on making fertilizers more environmentally friendly by reducing the potential for runoff into water sources as well as improving application methods and developing more concentrated formulas.

Research is also exploring new sources of fertilizers, especially organic options that can be produced sustainably. Manufacturers obtain the nutrients used in fertilizers from various sources, often through mining or other forms of extraction. The sources then go through processes to isolate the nutrients and convert them into usable forms before combining and packaging them into fertilizer mixtures. Fertilizer manufacturers extract nitrogen from the atmosphere through a process that results in the production of ammonia.

This process involves pumping natural gas and steam, followed by air, into a large vessel. Burning off the natural gas and steam removes the oxygen from the air. Introducing an electric current takes the carbon dioxide out of the air, resulting in the production of ammonia. Further processes may be applied to remove any impurities. Ammonia can be used as a fertilizer directly, but it is often converted into other substances to make handling easier.

For example, manufacturers convert ammonia into nitric acid through a process that uses catalysts in the presence of air and water. Combining ammonia and nitric acid creates ammonium nitrate, which has a high nitrogen concentration. Phosphorous can be found in phosphate rock.

To use the phosphate, though, you must isolate it from the ore. A typical method of achieving this is through the use of sulfuric acid, which produces phosphoric acid. Then the substance is reacted with sulfuric acid and nitric acid, which produces triple superphosphate. Manufacturers also blend phosphoric acid with ammonia, which creates ammonium phosphate.

Potassium used in fertilizer comes from potash, the term for the various potassium-containing minerals and compounds. The name comes from an early technique of obtaining potassium, which involved collecting wood ash in metal pots.

Most of the potash used in agriculture today is mined from rocks such as sylvanite, which formed when ancient seas evaporated, leaving concentrated minerals behind. Processors crush the rock, then use a flotation process to remove salt and clay before allowing the brine to dry and sizing it through screening.

Potassium chloride, potassium sulfate, potassium-magnesium sulfate, potassium thiosulfate, and potassium nitrate are all sources of potassium for fertilizer, with potassium chloride being the most prominent. Secondary nutrients and micronutrients are also obtained through processes that often involve mining and processing.

Calcium, for example, comes from limestone in the form of calcium carbonate, calcium sulfate, or calcium magnesium carbonate. Magnesium is sourced from dolomite. Sulfur is often a byproduct of other industrial processes. After manufacturers extract the raw elements, the material is shipped via barge to storage facilities throughout the world then supplied and sold in solid form from barge- bag quantity. Elements in liquid or gas forms will typically be transported through pipelines, railcars, or bulk trucks.

Fertilizer retailers mix the nutrients according to their formulas to create N-P-K fertilizer mixtures depending on soil deficiencies, often blending them in a large mixing containers.

These containers rotate in highly precise manners to produce mixtures to the required specifications. Fertilizers are used daily by farmers and families to help crops and gardens grow. Whether for a small garden of flowers and plants, or a large farm with thousands of acres of crops, a wide range of fertilizers have been developed to help different crops grow in different soil and weather conditions.

Chemical ingredients help create fertilizers that promote plant growth and are cost effective, too. Commercial and consumer fertilizers are strictly regulated by both individual states and the federal government to ensure that they are safe for the people who use them, people nearby, and the surrounding environment.

With the global population steadily growing, it is important that enough crops are produced each year to provide food, clothing and other agricultural products to people around the world.

Crops such as corn, wheat and cotton receive nutrients from the soil they are grown in; various crops deplete soil nutrients in different ways and rates. Some crop growth can deplete soil nutrients after just a few seasons of planting. Fertilizers play an important role in providing crops with the nutrients they need to grow and be harvested for nutritious food.

Fertilizer is the third highest volume commodity shipped by Canadian railways. Sustainable Over the last 40 years, farmland has been lost to the expansion of our cities and towns. Fertilizers allow us to produce more on our existing farmland.

By , the world will need to increase food production by 70 percent. Without fertilizer, global food production would be half of current levels, requiring farmers to grow more food on less land. Fertilizer helps to keep soils around the world productive to supply enough food for the growing population. In the last twenty years, the industry has achieved significant reduction in emission levels, while total production has increased.

The industry also helps farmers reduce their greenhouse gas emissions while achieving the maximum economic yield from their fields. Applying nitrogen fertilizers correctly reduces the amount of nitrous oxide emissions into the atmosphere.

Estimated Animal Agriculture Nitrogen and Phosphorus from Manure - Animal agriculture manure is a primary source of nitrogen and phosphorus to surface and groundwater. Manure runoff from cropland and pastures or discharging animal feeding operations and concentrated animal feeding operations CAFOs often reaches surface and groundwater systems through surface runoff or infiltration.

The USDA Agricultural Research Service has patented a new technology that can remove ammonia from livestock wastewater and recycle it as a fertilizer. EPA's longstanding policy encourages the beneficial reuse and recycling of industrial wastes. This includes hazardous wastes, when such wastes can be used as safe and effective substitutes for virgin raw materials. EPA is examining whether some fertilizers or soil conditioners contain potentially harmful containment levels.

However, the Agency believes that some wastes can be used beneficially in fertilizers when properly manufactured and applied.

Concerns have been raised regarding the use of certain wastes in the manufacture of agricultural fertilizers and soil amendments, and the potential for ecological or human health risks, as well as crop damage, when such fertilizers are applied to farmlands. For fertilizers that contain hazardous waste, EPA standards specify limits on the levels of heavy metals and other toxic compounds that may be contained in the fertilizer products. These concentration limits are based on the "best demonstrated available technology" for reducing the toxicity and mobility of the hazardous constituents.
