A fertilizer American English or fertiliser British English ; see spelling differences is any material of natural or synthetic origin other than liming materials that is applied to soil or to plant tissues to supply one or more plant nutrients essential to the growth of plants.

Many sources of fertilizer exist, both natural and industrially produced. Management of soil fertility has been the preoccupation of farmers for thousands of years. Egyptians, Romans, Babylonians, and early Germans are all recorded as using minerals and or manure to enhance the productivity of their farms. John Bennet Lawes , an English entrepreneur , began to experiment on the effects of various manures on plants growing in pots in , and a year or two later the experiments were extended to crops in the field.

One immediate consequence was that in he patented a manure formed by treating phosphates with sulfuric acid, and thus was the first to create the artificial manure industry. In the succeeding year he enlisted the services of Joseph Henry Gilbert , with whom he carried on for more than half a century on experiments in raising crops at the Institute of Arable Crops Research.

The Birkeland—Eyde process was one of the competing industrial processes in the beginning of nitrogen based fertilizer production. A factory based on the process was built in Rjukan and Notodden in Norway, combined with the building of large hydroelectric power facilities. The s and s witnessed the rise of the Haber process and the Ostwald process. The use of commercial fertilizers has increased steadily in the last 50 years, rising almost fold to the current rate of million tonnes of nitrogen per year.

A maize crop yielding 6—9 tonnes of grain per hectare 2. Controlled-nitrogen-release technologies based on polymers derived from combining urea and formaldehyde were first produced in and commercialized in In the s, the Tennessee Valley Authority National Fertilizer Development Center began developing sulfur-coated urea; sulfur was used as the principal coating material because of its low cost and its value as a secondary nutrient.

They typically provide 6 to 16 weeks of delayed release in turf applications. When a hard polymer is used as the secondary coating, the properties are a cross between diffusion-controlled particles and traditional sulfur-coated. Fertilizers enhance the growth of plants. This goal is met in two ways, the traditional one being additives that provide nutrients. The second mode by which some fertilizers act is to enhance the effectiveness of the soil by modifying its water retention and aeration.

This article, like many on fertilizers, emphasises the nutritional aspect. Fertilizers typically provide, in varying proportions : [13].

The nutrients required for healthy plant life are classified according to the elements, but the elements are not used as fertilizers. Instead compounds containing these elements are the basis of fertilizers. The macro-nutrients are consumed in larger quantities and are present in plant tissue in quantities from 0. Plants are made up of four main elements: hydrogen, oxygen, carbon, and nitrogen. Carbon, hydrogen and oxygen are widely available as water and carbon dioxide.

Although nitrogen makes up most of the atmosphere, it is in a form that is unavailable to plants. Nitrogen is the most important fertilizer since nitrogen is present in proteins , DNA and other components e.

To be nutritious to plants, nitrogen must be made available in a "fixed" form. Only some bacteria and their host plants notably legumes can fix atmospheric nitrogen N 2 by converting it to ammonia. Phosphate is required for the production of DNA and ATP , the main energy carrier in cells, as well as certain lipids. Micronutrients are consumed in smaller quantities and are present in plant tissue on the order of parts-per-million ppm , ranging from 0.

Because these elements enable catalysts enzymes their impact far exceeds their weight percentage. Fertilizers are classified in several ways. They are classified according to whether they provide a single nutrient e. Fertilizers are also sometimes classified as inorganic the topic of most of this article versus organic.

Inorganic fertilizers exclude carbon-containing materials except ureas. Organic fertilizers are usually recycled plant- or animal-derived matter. Inorganic are sometimes called synthetic fertilizers since various chemical treatments are required for their manufacture.

The main nitrogen-based straight fertilizer is ammonia or its solutions. Ammonium nitrate NH 4 NO 3 is also widely used. Urea is another popular source of nitrogen, having the advantage that it is solid and non-explosive, unlike ammonia and ammonium nitrate, respectively. The main straight phosphate fertilizers are the superphosphates. A mixture of single superphosphate and triple superphosphate is called double superphosphate.

Major two-component fertilizers provide both nitrogen and phosphorus to the plants. These are called NP fertilizers.

NPK rating is a rating system describing the amount of nitrogen, phosphorus, and potassium in a fertilizer. NPK ratings consist of three numbers separated by dashes e.

Fertilizers do not actually contain P 2 O 5 or K 2 O, but the system is a conventional shorthand for the amount of the phosphorus P or potassium K in a fertilizer. Most fertilizers are labeled according to this N-P-K convention, although Australian convention, following an N-P-K-S system, adds a fourth number for sulfur, and uses elemental values for all values including P and K. The main micronutrients are molybdenum, zinc, boron, and copper. These elements are provided as water-soluble salts.

Iron presents special problems because it converts to insoluble bio-unavailable compounds at moderate soil pH and phosphate concentrations.

For this reason, iron is often administered as a chelate complex , e. The micronutrient needs depend on the plant and the environment. For example, sugar beets appear to require boron , and legumes require cobalt , [1] while environmental conditions such as heat or drought make boron less available for plants. Nitrogen fertilizers are made from ammonia NH 3 , which is sometimes injected into the ground directly.

The ammonia is produced by the Haber-Bosch process. Deposits of sodium nitrate NaNO 3 Chilean saltpeter are also found in the Atacama desert in Chile and was one of the original nitrogen-rich fertilizers used.

In rare cases, fields are treated with the crushed mineral, but most often more soluble salts are produced by chemical treatment of phosphate minerals. The most popular phosphate-containing minerals are referred to collectively as phosphate rock.

These minerals are converted to water-soluble phosphate salts by treatment with sulfuric H 2 SO 4 or phosphoric acids H 3 PO 4. The large production of sulfuric acid as an industrial chemical is primarily due to its use as cheap acid in processing phosphate rock into phosphate fertilizer.

The global primary uses for both sulfur and phosphorus compounds relate to this basic process. This mixture can be combined with a potassium fertilizer to produce a compound fertilizer with the three macronutrients N, P and K in easily dissolved form. Potash is a mixture of potassium minerals used to make potassium chemical symbol: K fertilizers.

Potash is soluble in water, so the main effort in producing this nutrient from the ore involves some purification steps; e. Sometimes potash is referred to as K 2 O, as a matter of convenience to those describing the potassium content.

In fact, potash fertilizers are usually potassium chloride , potassium sulfate , potassium carbonate , or potassium nitrate. Compound fertilizers, which contain N, P, and K, can often be produced by mixing straight fertilizers. In some cases, chemical reactions occur between the two or more components. Fertilizers of an organic origin the first definition include animal wastes , plant wastes from agriculture, compost , and treated sewage sludge biosolids.

Beyond manures, animal sources can include products from the slaughter of animals — bloodmeal , bone meal , feather meal , hides, hoofs, and horns all are typical components.

No matter the definition nor composition, most of these products contain less concentrated nutrients, and the nutrients are not as easily quantified.

In terms of volume, peat is the most widely used packaged organic soil amendment. It is an immature form of coal and improves the soil by aeration and absorbing water but confers no nutritional value to the plants. It is therefore not a fertilizer as defined in the beginning of the article, but rather an amendment.

Coir , derived from coconut husks , bark, and sawdust when added to soil all act similarly but not identically to peat and are also considered organic soil amendments - or texturizers - because of their limited nutritive inputs. Some organic additives can have a reverse effect on nutrients — fresh sawdust can consume soil nutrients as it breaks down, and may lower soil pH — but these same organic texturizers as well as compost, etc.

Organic fertilizers such as composts and manures may be distributed locally without going into industry production, making actual consumption more difficult to quantify. Fertilizers are commonly used for growing all crops, with application rates depending on the soil fertility, usually as measured by a soil test and according to the particular crop.

Legumes, for example, fix nitrogen from the atmosphere and generally do not require nitrogen fertilizer. Fertilizers are applied to crops both as solids and as liquid.

The most widely used solid inorganic fertilizers are urea , diammonium phosphate and potassium chloride. Often solids are available as prills , a solid globule. Liquid fertilizers comprise anhydrous ammonia, aqueous solutions of ammonia, aqueous solutions of ammonium nitrate or urea.

These concentrated products may be diluted with water to form a concentrated liquid fertilizer e. Advantages of liquid fertilizer are its more rapid effect and easier coverage. Slow- and controlled-release involve only 0. Their utility stems from the fact that fertilizers are subject to antagonistic processes. In addition to their providing the nutrition to plants, excess fertilizers can be poisonous to the same plant.

Competitive with the uptake by plants is the degradation or loss of the fertilizer. Microbes degrade many fertilizers, e. Furthermore, fertilizers are lost by evaporation or leaching. Most slow-release fertilizers are derivatives of urea, a straight fertilizer providing nitrogen. Isobutylidenediurea "IBDU" and urea-formaldehyde slowly convert in the soil to free urea, which is rapidly uptaken by plants.

Besides being more efficient in the utilization of the applied nutrients, slow-release technologies also reduce the impact on the environment and the contamination of the subsurface water. Polymer coating of fertilizer ingredients gives tablets and spikes a 'true time-release' or 'staged nutrient release' SNR of fertilizer nutrients.

Controlled release fertilizers are traditional fertilizers encapsulated in a shell that degrades at a specified rate.

Any organic or inorganic material of natural or synthetic origin other than liming materials that is added to a soil to supply one or more plant nutrients essential to the growth of plants. Mineral fertilizer : A fertilizer material in which carbon is not an essential component of its basic chemical structure.

October 12, Water, food and resource scarcity, alongside increasing waste are among the main challenges humanity will face in the years to come. To take advantage of the waste, European researchers have come up with a novel nutrient management solution. Therefore, biowaste valorisation is considered an alternative, attractive approach in waste management policies. Most fertilisers currently rely heavily on fossil mineral resources for nutrient supply.

Biochar: A Sustainable Approach for Improving Plant Growth and Soil Properties

This study investigated the effects of applying anaerobically digested food waste and dairy manure-derived biofertilizers to processing tomatoes. The biofertilizers were produced from a pilot scale system consisting of coarse solid separation and ultrafiltration 5, Da with a capacity of approximately 3. The liquid concentrate and permeate from the system were both delivered to tomato plants through a subsurface drip fertigation system in a farm-scale cultivation experiment. The results showed that liquid digestate biofertilizers could be effectively delivered to the tomato plants given that steps to ensure suitable particle sizes were maintained prior to delivery. The ultrafiltered dairy manure digestate biofertilizer DMP had the highest yield of red tomatoes 7. The FWC biofertilizer produced tomatoes with significantly higher total and soluble solids contents compared to the synthetically fertilized tomatoes. Few significant differences between the treatments were observed among the pH, color, or size of the red tomatoes. These results indicate promise for the prospect of applying digestate biofertilizer products to tomatoes using the industry standard subsurface drip fertigation method. Additionally, digestate-derived biofertilizers may have potential to increase crop yields as well as certain quality characteristics of the harvested tomato fruit. No changes in soil quality were found among treatments but more study is required to understand long-term effects of biofertilizer applications with regards to soil quality and environmental risks.

Nitrogen Dynamics in Soil Fertilized with Slow Release Brown Coal-Urea Fertilizers

Soil is the most important source and an abode for many nutrients and microflora. Due to rapid depletion of agricultural areas and soil quality by means of ever-increasing population and an excessive addition of chemical fertilizers, a rehabilitated attention is a need of the hour to maintain sustainable approaches in agricultural crop production. Biochar is the solid, carbon-rich material obtained by pyrolysis using different biomasses. It has been widely documented in previous studies that, the crop growth and yield can be increased by using biochar.

Simply put, fertilizer combines the nutrients that plants need to grow — potassium, nitrogen, phosphorus, and sulphur— in a form they can digest. Think of it as plant food. As crops grow, they absorb, or mine, nutrients from the soil. When crops are harvested, so too are the nutrients absorbed by plants.

A n apple a day keeps the doctor away—but how do you bring enough apples, and other fresh food, all the way to Mars and back? Given the limits on how much cargo can be brought on any space journey, NASA has been exploring solutions to pack maximum nutrition into each bite. Astronauts already take vitamins and other nutritional supplements, but what if extra nutrients could be added to fruits and other plants as they grow? ZGSI , founded by year U. Department of Agriculture veteran John Wayne Kennedy. Kennedy was already working with NASA to explore cell replication and gene expression in microgravity when he began investigating the possibility of increasing the nutritional value of plants as they grow.

Space Farmers Could Grow Crops in Lunar and Martian Soil, Study Suggests

The main objective of this study was to compare the performance of two liquid organic fertilizers, an animal and a plant-based fertilizer, with mineral fertilization on citrus trees. The source of the fertilizer mineral or organic had significant effect in the nutritional status of the organic and conventionally managed mandarins. Nutrient uptake, vegetative growth, carbohydrate synthesis and soil characteristics were analyzed. Results showed that plants fertilized with animal based liquid fertilizers exhibited higher total biomass with a more profuse development of new developing organs leaves and fibrous roots. Liquid organic fertilization resulted in an increased uptake of macro and micronutrients compared to mineral fertilized trees. Moreover, organic fertilization positively affected the carbohydrate content fructose, glucose and sucrose mainly in summer flush leaves. Liquid organic fertilization also resulted in an increase of soil organic matter content.

Because the damage caused by chemical fertilizers is often long-term and cumulative, it may be wiser to consider alternative and sustainable methods of fertilizing the soil. Chemical fertilizers are important for the cost-effective production of commercial crops, and have been since the s. With a growing population and high cost of living, a bountiful harvest ensures enough food is available for everyone at affordable prices.

The beets Surendra Pradhan and Helvi Heinonen-Tanski grew were perfectly lovely: round and hefty; with their skin a rich burgundy; their flavor sweet and faintly earthy, like the dirt from which they came.

If humans ever set up colonies on the moon and Mars, the settlements will face one big problem: food security. If colonies grow large enough or last long enough, it will likely be impractical to resupply the colonies with constant food shipments from Earth. A new study, however, says there may be a solution right underfoot: many crops are able to grow directly in lunar and Martian soils. One was typical, garden-variety potting soil, another was simulated lunar dust, and a third was simulated Martian soil. While using the real deal would be the preferred option, no space agency has brought a sample of Martian soil back to Earth, and the pounds of moon soil and rocks brought back by the Apollo missions has been contaminated by air and humidity.
