Fertilizer

A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macronutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment, or hand-tool methods. Historically, fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations, and byproducts of human-nature industries (e.g. fish processing waste, or bloodmeal from animal slaughter). However, starting in the 19th century, after innovations in plant nutrition following Justus von Liebig's discoveries, an agricultural industry developed around synthetically created agrochemical fertilizers. This transition was important in transforming the global food system towards larger-scale industrial agriculture with large crop yields in monocultures. The invention of Haber process for producing ammonia for nitrogen in the 20th century combined with amplified chemical production capacity created during World War II led to a boom in using nitrogen fertilizers. In the latter half of the 20th century, increased use of nitrogen fertilizers (800% increase between 1961 and 2019) has been a crucial component of the increased productivity of conventional food systems as part of the so-called "Green Revolution". Fertilizers, especially when applied excessively, can have environmental consequences such as water pollution and eutrophication due to nutrient runoff. Additionally, the chemical process for creating the fertilizers results in byproducts, including carbon and other emissions. In some cases contamination and pollution of soil result by accumulation of heavy metals contained in some fertilizers collected through mining. Sustainable agricultural practices, such as reduced tillage and planting buffer strips, can minimize these adverse environmental effects.

• Nitrogen Fertilizers: Types, Benefits, And Application Tips

  ## Table Of Contents ## What Is A Nitrogen Fertilizer? Nitrogen fertilizer is a nitrogen-rich substance, either solid or liquid, widely used in agriculture to promote crop growth and unlock higher yields. Nitrogen (N) is a common component of fertilizers because it is essential for all plants to produce energy in their cells. There is not enough nitrogen in our soils to fully supply crop demands, particularly when you consider how much food the globe needs to feed everyone. To fill that shortfall, farmers all around the world rely on nitrogen in fertilizers (mostly synthetic). There are two types of nitrogen fertilizers based on their sources: forms of nitrogen fertilizers ## Forms On Nitrogen Fertilizer [...] ## Forms On Nitrogen Fertilizer Nitrogen fertilizers typically come in one of these forms: nitrate (NO3), ammonia (NH3), ammonium (NH4), or urea (CH4N2O). Every form has its own unique properties that dictate the specific conditions and methods for using it. Now, we’ll examine these forms and their characteristics more closely. ### Nitrate (NO3) [...] # Nitrogen Fertilizers: Why And How To Apply Sustainably Nitrogen fertilizers have become an indispensable tool in the modern farmer’s arsenal, but their use is not without its challenges. While they promote plant growth, enabling farmers to maximize harvests, their improper usage can lead to environmental hazards like groundwater contamination and greenhouse gas emissions. Since nitrogen fertilizer overapplication not only wastes resources but also poses agricultural and ecological risks, striking the right balance is crucial. This article delves into the intricacies of nitrogen-based fertilizers so that farmers can harness their benefits while mitigating potential drawbacks. Equipped with this knowledge, growers can cultivate crops that are both sustainable and abundant.

  Against the backdrop of climate change, soil depletion, and rising production costs, choosing the correct form and dose of nitrogen becomes critically important. ## Nitrogen Fertilizers: What Are They? Nitrogen fertilizers are mineral compounds that contain nitrogen in a form available for plant uptake. They are applied to improve soil fertility and ensure full growth of agricultural crops. The main feature of nitrogen fertilizers is that they supply one of the most important nutrients—nitrogen, which participates in the synthesis of proteins, enzymes, chlorophyll, and other biologically active substances. [...] Nitrogen in fertilizers can be present in three main forms: ammonium (NH₄⁺), nitrate (NO₃⁻), and amide (NH₂). Each has its own properties: the ammonium form is better retained in the soil, the nitrate is quickly absorbed by plants, and the amide requires enzymatic conversion. In terms of physical form, nitrogen fertilizers come as solids (granules, powders) and liquids (e.g., UAN solution). Using nitrogen fertilizers can significantly increase yield but requires precise dosing, as excess nitrogen leads to excessive vegetative growth, reduced product quality, and environmental pollution risks. ## Importance of Nitrogen Fertilizers for Plants [...] ## Types of Nitrogen Fertilizers Nitrogen is one of the key elements without which it is impossible to achieve a stable and quality yield. Its participation in the synthesis of proteins, chlorophyll, and growth regulation makes nitrogen fertilizers the foundation of nutrition for most agricultural crops. However, the effectiveness of such fertilizers depends not only on their composition but also on application conditions, soil type, and crop characteristics. Incorrect dosing or form of nitrogen can not only reduce results but also cause nutrient losses and environmental harm. To avoid mistakes, it is important to understand what types of nitrogen fertilizers exist, how they differ, and how to use them correctly. ### Urea (Carbamide)

  Cropler wants to make farming easier through modern technology, and improved fertilization is a big part of that. So let's discuss fertilizers with nitrogen, and how to safely use them to improve your fields and harvests. ## What Are Nitrogen Fertilizers? N fertilizers are simply additives, in either solid or liquid form, that add nitrogen to the soil. They may come as part of a more comprehensive fertilizer that also includes compounds such as phosphates and potassium, or they may only add nitrogen. ## The Three Forms of Nitrogen Fertilizer Regardless of whether the source is organic or synthetic, nitrogen fertilizers come in three types: Nitrate, Ammonia/Ammonium, and Urea. [...] ## Organic vs Synthetic Nitrogen Fertilizers Nitrogen fertilizers can be divided up into two broad types, natural or synthetic. Natural N fertilizers are derived from nitrogen-rich substances such as manure, fish emulsions, or compost. Synthetic fertilizers are created in a lab by using N2 gas and transforming it into solid or liquid forms. The discussion over natural vs synthetic fertilizers is complicated, and we've covered it previously in more detail. To summarize: Natural fertilizers tend to be more expensive and more labor-intensive. In addition, they take longer to work. However, they have been repeatedly shown to be much better for long-term soil health, as well as reducing environmental pollution. [...] Nitrogen is one of the basic substances needed for life on Earth. While nitrogen gas (N2) is plentiful in the atmosphere — making up approximately 78% of the air we breathe — most plants are unable to take nitrogen directly from the air. They must instead pull it from the soil, depleting the soil in the process. This makes nitrogen-based fertilizers one of the single most important additives in modern farming. However, N fertilizers cannot be used mindlessly. Using the wrong type of fertilizer, or too much of it, can cause serious problems for your crops and your land overall.

  Mengel, Purdue University; Co-editors The common N fertilizers are anhydrous ammonia (82 percent N), urea (46 percent N), solutions (28 to 32 percent N), ammonium sulfate (21 percent N) and ammonium nitrate (34 percent N).Anhydrous ammonia (82 percent) is the slowest of all N fertilizer forms to convert to nitrate N.Therefore, it would have the least chance of N loss due to leaching or denitrification. It must be injected into the soil; therefore, it would have no loss due to sur-face volatilization.The disadvantage of anhydrous ammonia is that it is hazardous to han-dle. It must be injected into the soil, and on steep slopes erosion can be a problem. Urea (46 percent) converts to nitrate N fairly quickly, usually in less than two weeks in the spring. Denitrification on wet or compacted [...] Nitrogen solutions can be banded on the soil surface easily by dribbling.This method of application minimizes the amount that sticks to the residue and, therefore, minimizes sur-face volatilization but may not eliminate it.Ammonium sulfate (21 percent) is a nitrogen source with little or no surface volatilization loss when applied to most soils.Ammonium sulfate is a good source of sulfur when it is needed. Its disadvantage is that it is the most acidifying form of N fertilizer—it requires approximately 2 to 3 times as much lime to neu-tralize the same amount of acidity as formed by other common N carriers.

• The Facts: Nitrogen Fertilizer | Mosaic Crop Nutrition

  All N fertilizer begins with a source of hydrogen gas and atmospheric N that are reacted to form ammonia.The most-used source of hydrogen is natural gas (methane). Other sources of hydrogen, such as coal, are used in some regions. After hydrogen and N are combined under conditions of high temperature and pressure to form ammonia, many other important N-containing fertilizers can then be made. Urea is the most common N fertilizer, but many more excellent N fertilizers derive from ammonia. For example, some ammonia is oxidized to make nitrate fertilizer. This same conversion of ammonia to nitrate takes place in agricultural soils through the microbial process of nitrification. [...] Nitrogen fertilizers clearly make an essential contribution to maintaining an adequate supply of nutritious food. However, careful management is required to keep N fertilizer in the form and in the location where it can be most useful for sustaining healthy plant growth. The tremendous benefits from N fertilizer must be balanced with the disruptive environmental impacts that may arise when N moves into areas where it’s not wanted.

While N isn’t found in mineral forms like phosphorus (P) or potassium (K), it’s largely present in organic compounds. Soil-based N undergoes many complex biological transformations that make it challenging to manage. Many metabolic processes in plants and animals rely on nitrogen. Perhaps the best-known role of N is in forming amino acids, which make up the building blocks of protein. The human daily protein requirement ranges between 40 and 70 grams, depending on gender, age and size.
