How are fertilizers made?
How fertilizers are made? Each year, the European fertilizer industry transforms millions of tons of air, natural gas and mined ores into products based on the three essential plant nutrients nitrogen, phosphorus and potassium.
Can farmers reduce fertilizer use without sacrificial food production?
In this article I show that farmers in many countries can reduce fertilizer use without sacrificing food production. Crops, like any organism, need nutrients to grow. When particular nutrients are lacking, they fail or grow at a much slower rate. These are called ‘limiting nutrients’.
Who invented fertilizer?
According to Nelson (1990), the first documented use of fertilizer in the U.S. was by Native Americans who lived along certain streams in New England and New York and used fish caught in these streams to fertilize corn.
How much do synthetic fertilizers increase crop yields?
Utilizing a range of long-term evaluations, spanning a total of 362 seasons of crop production, of crop yields and nutrient budgets across the world, Stewart et al. (2005) concluded that between 30-50 percent of yield increases could be attributed to synthetic fertilizer inputs (and typically even higher in the tropics). 10
How does artificial fertilizer work?
The application of a synthetic fertilizer actually kills a significant percentage of beneficial microorganisms. These tiny creatures are responsible for breaking down organic matter into a stable amendment for improving soil quality and fertility. Some convert nitrogen from the air into a plant useable form.
How is artificial fertilizer produced?
It is made by combining the nitrogen in the air with hydrogen in methane to produce ammonia (NH3). The ammonia is then used to create other forms of nitrogen including ammonium nitrate and urea (ammonia + CO2). Natural gas is used to provide the methane and a heat source for the process.
What is artificial fertilizer?
Artificial fertilisers are manufactured from petrol or natural gas. They can contain a wide variety of nutrients including nitrates, magnesium, phosphorous and potassium. Fertilisers that contain nitrogen, phosphorous and potassium are called NPK fertilisers.

How is artificial nitrogen fertilizer produced?
Nitrogen fertilizers U.S. Nitrogen fertilizers are made from ammonia (NH3) produced by the Haber-Bosch process. In this energy-intensive process, natural gas (CH4) usually supplies the hydrogen, and the nitrogen (N2) is derived from the air.
What are natural and artificial fertilizers?
The Difference Between Natural and Artificial Fertilizers Natural fertilizers get these nutrients from sources like manure, compost, and blood meal. On the other hand, synthetic fertilizers are derived from man-made compounds like ammonium phosphate and potassium sulfate.
What are the advantages of artificial fertilizers?
Synthetic:Faster acting. They’re faster acting than organic making them a good choice for aiding plants in severe distress from nutrient deficiencies.Easy to handle. These fertilizers, which come as dry, granular pellets or water-soluble products, also provide even, consistent feeding.Inexpensive.
How do artificial fertilisers affect the environment?
In short, synthetic fertilizers can harm the environment because their nitrogen and phosphorous levels are often higher. Phosphorous runoff from farms and landscapes that use fertilizer has contributed to the algae bloom in Lake Erie, which has been disastrous to aquatic life in the region.
What is artificial fertilizer made of?
Synthetic fertilizers are those composed of the synthesized chemicals of nitrogen, phosphorus and potassium.
How are fertilizers applied?
Fertilizer is applied in bands near where developing roots will easily reach it; either to the side and below the seed rows, slightly below the seeds, or in between rows. A common practice is to band fertilizer 2 inches to the side and 2 inches deeper than the seeds or plants.
What are the methods of applying fertilizer?
The different methods of fertilizer application are as follows:a) Broadcasting.b) Placement.a) Starter solutions.b) Foliar application.c) Application through irrigation water (Fertigation)d) Injection into soil.e) Aerial application.
What is biosolid fertilizer?
Fertilizers made from domestic septage and sewage sludge (biosolids) Biosolids are nutrient-rich organic materials resulting from the treatment of domestic sewage in a treatment facility. When treated and processed, these residuals can be recycled and applied as fertilizer to improve and maintain productive soils and stimulate plant growth.
What are the sources of nitrogen and phosphorus pollution?
Sources and Solutions: Agriculture – Animal manure, excess fertilizer applied to crops and fields, and soil erosion make agriculture one of the largest sources of nitrogen and phosphorus pollution in the country.

Regenerative vs. Organic or Sustainable Agriculture
There are widely differing beliefs on what it means to be regenerative on our ranches and farms. Some hold that regenerative equates to organic or sustainable, but, while they share some similarities, they are not the same. Organic and sustainable systems concentrate on the type and level of inputs, including fertilizers, used for production.
How Can Regenerative Agriculture Replace Synthetic Fertilizers?
One of the most promising aspects of regenerative agriculture is that diverse, active soil biology can replace fertilizers and supply adequate plant nutrition to growing forages in well managed, regenerative pastures and crop fields.
Biological Diversity Is Key to Success
One common thread for successful practitioners of regenerative agriculture is having biological diversity in their production systems. Monoculture pastures, such as bermudagrass or tall fescue, will have soil biology but do not have enough species richness to provide effective nutrient cycling to meet forage needs.
Does Eliminating Fertilizer Hurt Ranch Productivity?
A major barrier that farmers and ranchers face when implementing regenerative practices is working through the initial drop in the land’s productivity that will probably occur when fertilizer is reduced or removed.
If Fertilizers Are Used
IF fertilizers are going to be used, the long-time rule of testing soils first still applies:
Follow the 4R Principles
IF fertilizers are deemed necessary in a particular situation, it is important that their applications still follow the 4R principles of nutrient management.
What are the benefits of synthetic fertilizer?
Benefits of Synthetic Fertilizers. Synthetic fertilizers supply consistent amounts of precise nutrients to the soil. They act on soil immediately — unlike organic fertilizers that need to break down before absorption. This immediate efficacy is especially beneficial to dying or severely malnourished plants.
What is organic fertilizer?
Organic fertilizers are naturally occurring substances and include biofertilizers, green manure, organic manure and compost. They slowly leach essential nutrients into the soil and improve its overall vitality with time. Synthetic fertilizers are man-made combinations of chemicals and inorganic substances.
How does fertilizer affect aquatic ecosystems?
Fertilizers that leach into streams, rivers, lakes and other bodies of water disrupt aquatic ecosystems. Synthetic fertilizers increase the nitrate levels of soil. Plants produced from such soil, upon consumption, convert to toxic nitrites in the intestines.
How did synthetic fertilizer affect agriculture?
Their use increased crop yields and brought on an agricultural revolution, the likes of which the world had not seen before. Synthetic fertilizers continue to have far-reaching effects, both positive and negative, and are likely to remain a part of human life for some time to come.
How to prevent runoff when it rains?
Mix synthetic fertilizer well into the soil. This will prevent runoff when it rains. Dilute your water-soluble synthetic fertilizer well before use, as Oregon State University’s OSU Extension Service warns that it’s easy to apply too much chemical fertilizer because it’s so concentrated. Improperly diluted fertilizer can burn your plants. Wash all vegetables and fruit yield from synthetically treated soil thoroughly before eating. Keep unused fertilizer away from water, pets and children. Consider switching to organic fertilizers, which are safer and cause no pollution.
Is synthetic fertilizer more expensive than organic fertilizer?
The University of Maryland Extension states that synthetic fertilizers are generally less expensive than organic fertilizers. The institute of higher learning also points out that chemical fertilizers are able to deliver nutrients in higher concentrations than their natural counterpart.
Can fertilizer burn plants?
Improperly diluted fertilizer can burn your plants. Wash all vegetables and fruit yield from synthetically treated soil thoroughly before eating. Keep unused fertilizer away from water, pets and children. Consider switching to organic fertilizers, which are safer and cause no pollution.

Phosphate rock is primarily treated with sulphuric acid to produce phosphoric acid, which is either concentrated or mixed with ammonia to make a range of phosphate (P2O5) fertilizers.
What is the third major plant and crop nutrient?
POTASSIUM (K) Potassium is the third major plant and crop nutrient. Potassium-based fertilizers are also produced from mined ores. Several chemical processes can be used to convert the potash rock into plant food, including potassium chloride, sulphate and nitrate.
What is ammonia used for?
The ammonia is used to make nitric acid, with which it is then mixed to produce nitrate fertilizers such as ammonium nitrate (AN). Ammonia may also be mixed with liquid carbon dioxide to create urea.
What are the three essential nutrients in fertilizer?
Each year, the European fertilizer industry transforms millions of tons of air, natural gas and mined ores into products based on the three essential plant nutrients nitrogen, phosphorus and potassium.
How is nitrogen fertilizer made?
For nitrogen-based fertilizers, the largest product group, the process starts by mixing nitrogen from the air with hydrogen from natural gas at high temperature and pressure to create ammonia. Approximately 60% of the natural gas is used as raw material, with the remainder employed to power the synthesis process.
SF: How does innovation play a role in tackling growing demand for alternative solutions?
TB: Innovation is what really leads to those revolutionary changes. Without innovation, you’re caught in the cycle of very incremental changes and improvements. In nutrient efficiency, we’re lucky right now that there’s been a lot of innovation around a variety of alternatives.
SF: As one of the panelists in the Rethinking Synthetic Fertilizer: The Race for Alternatives session, what do you hope attendees take away?
TB: There is a nice mix of both fertilizer incumbents and start-ups on the panel, which can provide interesting perspectives from all sides of the industry. The path a large company takes toward nutrient efficiency compared to the one a small company may take can be very different.
SF: Where does Sound Agriculture want nutrient efficiency to go?
TB: We want to see fertilizer used in the most sustainable and the most profitable way. We see those as completely compatible, especially with fertilizer prices the way they are right now. Overapplication of fertilizer really does hurt a gross bottom line, and it also hurts the sustainability profile of the farm.
SF: Where does Sound Agriculture see the greatest demand for alternatives to fertilizers? Is it in corn? Is it in soybeans? Is it across the board?
TB: Typically, we see the most demand in corn. With nitrogen prices the way they are right now, demand for alternatives has gone through the roof not only for corn but also in other crops like soybeans and wheat.
SF: How do we bring these alternative solutions like the ones Sound Agriculture is developing to farmers?
TB: Our route to market is a little bit unique. We sell through dealers, and we also sell direct to growers. Our partnership with Mosaic is focused on developing a new product. We’re open to exploring pretty much any, and all routes to put a great solution in the hands of growers. Our route to market is designed to remove the friction for a grower.
SF: Why is an event like World Agri-Tech Innovation Summit so important for a start-up like Sound Agriculture?
TB: This will be our fourth time attending the summit. It’s one of my favorite conferences on ag tech because it’s a gathering place for a lot of people from diverse parts of the industry. It can be hard to get your message out there. If I can meet people in person, have a face-to-face conversation, that’s key to increasing our visibility.
What are the three nutrients that are needed for agriculture?
In addition to water and sunlight, crops need three key nutrients to grow: nitrogen, phosphorous and potassium.
How much protein was produced by nitrogen fertilizer in the 1990s?
Since nitrogen fertilizer provided around half of the nutrient in this harvested crop, he estimated that it provided 40 percent of dietary protein in the mid-1990s. He concluded that 40 percent of the global population in 2000 were dependent on food production from synthetic fertilizers.
How much of the world’s population is supported by nitrogen fertilizer?
In fact, it’s estimated that nitrogen fertilizer now supports approximately half of the global population. In other words, Fritz Haber and Carl Bosch — the pioneers of this technological breakthrough — are estimated to have enabled the lives of several billion people, who otherwise would have died prematurely, or never been born at all. 4.
What is the limiting nutrient for crop production?
Nitrogen is often the nutrient that is limiting to further crop production, despite Earth’s atmosphere containing more than 78 percent. This is because in the atmosphere, nitrogen exists in its largely unreactive N 2 form, rather than in a reactive form which plants can utilize.
When did nitrogen fertilizer become available?
As we see, nitrogen fertilizers only became available following the commercialization of the Haber-Bosch process from 1910 onwards. Since then, Erisman et al. estimate it has supported 42 percent of global births over the past century.
What were the factors that led to the growth of crop yields in the 20th century?
Fertilizer application, combined with other product ivity factors such as improved crop varieties, genetic breeding, irrigation and mechanization led to a significant inflection in crop yield trends across the world in the 20th century.
What does the red line represent?
The red line represents the size of the global population which would therefore be supported without the use of nitrogenous fertilizers. This is shown simply as the actual population minus the number of people reliant on them for food production.
What are the major ammonia producers in North America?
The largest ammonia producing companies in North America are CF Industries, Nutrien, Mosaic, and Yara (Nutrien 2020). Nitrogen fertilizer production facilities operate every day but have limited storage capacity, so fertilizer must be transported to warehouses and terminals for storage.
What is the process of forming ammonia?
The Haber-Bosch process utilizes hydrogen and atmospheric nitrogen under extremely high pressure and temperature in combination with a metal catalyst such as iron to produce ammonia gas, which is condensed with the help of cold water, forming liquid ammonia also known as anhydrous ammonia (Figure 1A).
What percentage of the atmosphere is nitrogen?
Nitrogen is the most abundant gas in the atmosphere and makes up approximately 78% of the atmosphere. One of the most important scientific discoveries …
When did fertilizer use increase?
Fertilizer use increased from 1870-1920, and the development and distribution of information about nitrogen fertilizer practices through agricultural institutions, state extension services, field experiments, and the USDA led to better fertility practices and improved fertilizer use on farms.
Does phosphate fertilizer provide nitrogen?
It is also relevant mentioning that some phosphate fertilizers such as mono and diammonium phosphate (MAP and DAP) can indirectly supply nitrogen for crop production, although these fertilizers are mainly used to provide phosphorus. Nitrogen Fertilizer Manufacturers in the U.S.
Is nitrogen fertilizer anhydrous or anhydrous?
Many other nitrogen fertilizers can be prepared from anhydrous ammonia, and some of them, like calcium nitrate and ammonium sulfate have received more attention in other regions like Europe and Latin America, however, their low nitrogen content is a disadvantage, reflecting a higher logistic cost of these fertilizers.
Is ammonium nitrate safe to use in fertilizer?
A safer option arises from the mixture of ammonium nitrate, urea, and water forming the UAN solutions (Figure 1B). These fluid fertilizers have been gaining increasing attention in fertilizer markets because they are safe to handle, convenient to mix with other nutrients and chemicals, and easily applied.
