When manufacturers list a fertilizer as organic, it means the nutrients were once part of, or created by, a living plant or animal.Nitrogen, phosphorous and potassium are the three most important nutrients, alongside trace elements such as iron, boron and zinc.Depending on the mining and extracting process, potassium chloride granules vary in size, color and solubility.Although diammonium phosphate and its attached nitrogen has increased in market share, triple superphosphate remains popular as a phosphorous source in granular fertilizers. .

Fertilizers supplement plants with the vital nutrients needed for optimal, healthy growth.Multinutrient formulas include complete and balanced fertilizers, which contain basic nutrients, such as nitrogen, phosphorus and potassium, as well as secondary and micronutrients such as calcium, magnesium, boron and manganese.The percentage of nitrogen, phosphorus and potassium contained in both complete and balanced fertilizers is indicated by three numbers on the package.A typical slow-release fertilizer releases nutrients over a period of 50 days to a year, reducing the chance of burning the plant or root system.These fertilizers contain high levels of nitrogen, one of the most vital nutrients for plant growth.Potassium nitrate is easy to apply, because it does not pull moisture from the air, but it does slightly increase the pH of the soil upon application.Inorganic phosphorus fertilizers such as rock phosphate remain in the soil years after the initial application. .

Fertilizers typically provide, in varying proportions, the three major plant nutrients (nitrogen, phosphorus, and potassium), the secondary plant nutrients (calcium, sulfur, magnesium), and sometimes trace elements (or micronutrients) with a role in plant nutrition: boron, chlorine, manganese, iron, zinc, copper and molybdenum.Inorganic fertilizers (Mineral Fertilizer).FERTILIZERS can be divided into macronutrients or micronutrients based on their concentations in plant dry matter.The macronutrients are consumed in larger quantities and normally present as whole number or tenths of percentages in plant tissues.An 18−51−20 fertiliser therefore contains, by weight, 18% elemental nitrogen (N), 22% elemental phosphorus (P) and 16% elemental potassium (K).In general, agricultural fertilizers contain only one or two macronutrients.Many controlled release fertilizers are intended to be applied approximately every 3-6 months, depending on watering, growth rates, and other conditions, whereas water-soluble fertilizers must be applied at least every 1-2 weeks and can be applied as often as every watering if sufficiently dilute.Chemist Justus von Liebig (in the 19th century) contributed greatly to understanding the role of inorganic compounds in plant nutrition and devised the concept of Liebig's barrel to illustrate the significance of inadequate concentrations of essential nutrients.Nitrogen fertilizer is often synthesized using the Haber-Bosch process, which produces ammonia.This ammonia is applied directly to the soil or used to produce other compounds, notably ammonium nitrate, a dry, concentrated product.Organic fertilizers.Naturally occurring minerals such as mine rock phosphate, sulfate of potash and limestone are also considered Organic Fertilizers.Then there is the matter of how effective they are at promoting plant growth, chemical soil test results aside.Since the majority of nitrogen supplying organic fertilizers contain insoluble nitrogen and are slow release fertilizers their effectiveness can be greater than conventional nitrogen fertilzers.Organics also have the advantage of avoiding certain long-term problems associated with the regular heavy use of artificial fertilizers:.This results in prohibitive transportation and application costs, especially where the agriculture is practiced a long distance from the source of the organic fertilizer.In practice a compromise between the use of artificial and organic fertilizers is common, typically by using inorganic fertilizers supplemented with the application of organics that are readily available such as the return of crop residues or the application of manure.Some approved fertilizers may be inorganic, naturally occurring chemical compounds, e.g. minerals...When prolonged algae blooms occur over many years, the effect is a process called eutrophication.It is also possible to over-apply organic fertilizers.However: their nutrient content, their solubility, and their release rates are typically much lower than chemical fertilizers, partially because by their nature, most organic fertilizers also provide increased physical and biological storage mechanisms to soils.For these reasons, it is recommended that knowledge of the nutrient content of the soil and nutrient requirements of the crop are carefully balanced with application of nutrients in inorganic fertiliser especially. .

Many of the commonly available inorganic fertilizers are described below, and their analyses are summarized in Appendixes, D, E, amd F.Although orthophosphate’s negative charge prevents it from being attracted by the soil’s cation exchange capacity (CEC), it does react strongly in the soil, primarily with the large amount of iron and aluminum naturally in the soil, to form products that are very insoluble and thus unavailable to plants.There are numerous sources of calcium, magnesium, and sulfur for fertilizing grapevines.In addition, materials such as bone meal, wood ash, manures and sludge can contain adequate amounts of these elements.Chelates of zinc, manganese, iron, and copper have become standard products for foliar application in many vineyards.Chelating agents for various micronutrient metals include EDTA, HEEDTA, NTA, DTPA, and EDDHA.EDTA is the most common synthetic chelating agent and is used for both soil and foliar applied nutrients. .

Many sources of fertilizer exist, both natural and industrially produced.[1] For most modern agricultural practices, fertilization focuses on three main macro nutrients: Nitrogen (N), Phosphorus (P), and Potassium (K) with occasional addition of supplements like rock dust for micronutrients.In the later half of the 20th century, increased use of nitrogen fertilizers (800% increase between 1961 and 2019) have been a crucial component of the increased productivity of conventional food systems (more than 30% per capita) as part of the so-called "Green Revolution".The use of fertilizer has also led to a number of direct environmental consequences: agricultural runoff which leads to downstream effects like ocean dead zones and waterway contamination, soil microbiome degradation,[3] and accumulation of toxins in ecosystems.Indirect environmental impacts include: the environmental impacts of fracking for natural gas used in the Haber process, the agricultural boom is partially responsible for the rapid growth in human population and large-scale industrial agricultural practices are associated with habitat destruction, pressure on biodiversity and agricultural soil loss.The Birkeland–Eyde process was one of the competing industrial processes in the beginning of nitrogen-based fertilizer production.The Haber process produces ammonia (NH 3 ) from methane (CH 4 ) gas and molecular nitrogen (N 2 ).A maize crop yielding 6–9 tonnes of grain per hectare (2.5 acres) requires 31–50 kilograms (68–110 lb) of phosphate fertilizer to be applied; soybean crops require about half, as 20–25 kg per hectare.One of the plants in the nutrient-poor soil has died.The nutrients required for healthy plant life are classified according to the elements, but the elements are not used as fertilizers."Multinutrient fertilizers" (or "complex fertilizers") provide two or more nutrients, for example N and P. Fertilizers are also sometimes classified as inorganic (the topic of most of this article) versus organic.Inorganic are sometimes called synthetic fertilizers since various chemical treatments are required for their manufacture.Single nutrient ("straight") fertilizers [ edit ].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.Major two-component fertilizers provide both nitrogen and phosphorus to the plants.The main NP fertilizers are monoammonium phosphate (MAP) and diammonium phosphate (DAP).NPK fertilizers are three-component fertilizers providing nitrogen, phosphorus, and potassium.Compound NPK fertilizers contain chemically bound ingredients, while blended NPK fertilizers are physical mixtures of single nutrient components.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.g., 10-10-10 or 16-4-8) describing the chemical content of fertilizers.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.Micronutrients [ edit ].Typical micronutrients are boron, zinc, molybdenum, iron, and manganese.[20] These elements are provided as water-soluble salts.Production [ edit ].Nitrogen fertilizers [ edit ].Nitrogen fertilizers are made from ammonia (NH 3 ) produced by the Haber-Bosch process.[33] Nitrates are also produced from ammonia by the Ostwald process.Phosphate fertilizers [ edit ].These minerals are converted into water-soluble phosphate salts by treatment with sulfuric (H 2 SO 4 ) or phosphoric acids (H 3 PO 4 ).Potassium fertilizers [ edit ].Chemical granulation process is based on chemical reactions between liquid raw materials (such as phosphoric acid, sulphuric acid, ammonia) and solid raw materials (such as potassium chloride, recycle material).Organic fertilizers [ edit ].On the other hand, marketed "organic fertilizers" may include, and promote, processed organics because the materials have consumer appeal.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.).may increase the availability of nutrients through improved cation exchange, or through increased growth of microorganisms that in turn increase availability of certain plant nutrients.Application [ edit ].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.Liquid vs solid [ edit ].Fertilizers are applied to crops both as solids and as liquid.Urea [ edit ].During summer, urea is often spread just before or during rain to minimize losses from volatilization (a process wherein nitrogen is lost to the atmosphere as ammonia gas).Because of the high nitrogen concentration in urea, it is very important to achieve an even spread.Foliar application [ edit ].Various chemicals are used to enhance the efficiency of nitrogen-based fertilizers.The conversion of urea to ammonia catalyzed by enzymes called ureases.[46] Fertilizer use (2018).[48] Agricultural and chemical minerals are very important in industrial use of fertilizers, which is valued at approximately $200 billion.[49] Nitrogen has a significant impact in the global mineral use, followed by potash and phosphate.Environmental effects [ edit ].Water [ edit ].Phosphorus and nitrogen fertilizers when commonly used have major environmental effects.[65][66] If eutrophication can be reversed, it may take decades[citation needed] before the accumulated nitrates in groundwater can be broken down by natural processes.Nitrate pollution [ edit ].[67] High application rates of nitrogen-containing fertilizers combined with the high water solubility of nitrate leads to increased runoff into surface water as well as leaching into groundwater, thereby causing groundwater pollution.[68][69][70] The excessive use of nitrogen-containing fertilizers (be they synthetic or natural) is particularly damaging, as much of the nitrogen that is not taken up by plants is transformed into nitrate which is easily leached.[72] The nutrients, especially nitrates, in fertilizers can cause problems for natural habitats and for human health if they are washed off soil into watercourses or leached through soil into groundwater.Soil [ edit ].Accumulation of toxic elements [ edit ].Phosphate rocks contain high levels of fluoride.Radioactive elements [ edit ].[81][88] Uranium-238 concentrations can range from 7 to 100 pCi/g in phosphate rock[89] and from 1 to 67 pCi/g in phosphate fertilizers.Highly pure fertilizers are widely available and perhaps best known as the highly water-soluble fertilizers containing blue dyes used around households, such as Miracle-Gro.Trace mineral depletion [ edit ].[101] Although improved crop yields resulting from NPK fertilizers are known to dilute the concentrations of other nutrients in plants,[100][102] much of the measured decline can be attributed to the use of progressively higher-yielding crop varieties that produce foods with lower mineral concentrations than their less-productive ancestors.Changes in soil biology [ edit ].Energy consumption and sustainability [ edit ].In the US in 2004, 317 billion cubic feet of natural gas were consumed in the industrial production of ammonia, less than 1.5% of total U.S. annual consumption of natural gas.[109] A 2002 report suggested that the production of ammonia consumes about 5% of global natural gas consumption, which is somewhat under 2% of world energy production.The effects can be combined into an equivalent amount of carbon dioxide.The amount varies according to the efficiency of the process.Through the increasing use of nitrogen fertilizer, which was used at a rate of about 110 million tons (of N) per year in 2012,[118][119] adding to the already existing amount of reactive nitrogen, nitrous oxide (N 2 O) has become the third most important greenhouse gas after carbon dioxide and methane.Two types of agricultural management practices include organic agriculture and conventional agriculture.Conventional agriculture uses all the components that organic agriculture does not use.

Revisiting the original reasons for excluding inorganic fertilizers in

The decision to ban inorganic fertilizers in organic farming is inconsistent with our current scientific understanding.This paper analyzes the original arguments in the different schools of organic agriculture on prohibiting the use of inorganic fertilizers and re-evaluates these reasons based on accumulated science and evidence.The reasons cited for not using mineral fertilizers were then treated as scientific hypotheses, following the principles of the philosophy of science (Popper, 1959), and tested for their validity.He described “auras” and “forces” around organisms, phenomena that are not known to science.(Steiner, 1924: 20) “Man hört heute sehr oft die Phrase: der Dünger enhalte die Futterstoffe für die Pflanzen.(Steiner, 1924: 176) Essentially, a living soil and “living forces” were singled out as being most important for crop production, while inorganic fertilizers were identified as being responsible for quality deterioration not providing “living forces.” The term “living forces” was explained by Steiner as forces surrounding organisms.The “etheric aura” of plants was seen as the receiver of “living forces.” The auras and forces mentioned by Steiner are not known to science, but nevertheless there have been several attempts to visualize them.Forms and colors of the electrical discharge zone around a plant are thus not an intrinsic plant quality, but a random effect of the water content, and do not represent etheric auras.The crystallization pattern formed during evaporation was interpreted as showing the plant’s organized and formative “forces.” The more regular the pattern the better, with irregularity taken to indicate less organized plant “forces.” From a scientific perspective, crystallization of plant solution with copper chloride during evaporation is primarily affected by the concentration of compounds in the plant juice and their reactions with copper chloride.Steiner’s descriptions of such phenomena were based on his spiritual experience (Kirchmann, 1994).The statement by Steiner that our view about the function of minerals as nutrients for crops is completely wrong is not substantiated by science.There is no evidence to support Steiner’s statement that science must “correct itself” about the nutritional role of minerals for plants.His statement (hypothesis) of “living forces” affecting crops cannot be tested, and is thus not falsifiable.Example of environmental benefit using inorganic fertilizer Some Swedish literature references from similar organic and conventional rotations were compiled (Table 1) to illustrate how N leaching losses are affected by the exclusive use of inorganic or organic N. Supply of N in the organic rotations was exclusively through legumes (Aronsson et al., 2007; Stenberg et al., 2012; Torstensson et al., 2006).Expressing leaching losses per unit product (Table 2), showed that organic rotations resulted in consistently higher leaching losses ranging from 3.6 to 11.6 kg N Mg−1 organic yield as compared to 0.8 to 6.6 kg N Mg−1 conventional yield.The reasons they gave for banning inorganic fertilizers could not be verified at the time, due to poor understanding of nutrient turnover in soil-plant systems, insufficient experience, and lack of scientific methodology.Their decision criteria were found to have no scientific legitimacy, and thus exclusion of inorganic fertilizers cannot be categorized as a principle based on science.Modern science requires invalid hypotheses to be rejected and false concepts to be corrected, so if theories and principles are maintained despite lack of evidence, science is ignored.
