Monoammonium phosphate
Monoammonium phosphate (MAP) is a popular source of nitrogen (N) and phosphorus (P). It is constructed of two components that are often used in the fertiliser business and has the highest phosphorus content of any typical solid fertiliser. MAP is a key component in several fire extinguishers as well as fertilisers for crops. Additionally, it has a big role in optics and electronics.
It is a water-soluble fertilizer with high Phosphate content along with the optimum amount of Nitrogen. It is readily soluble in water and is best for drip irrigation and foliar application of fertilizer.
By volume, monoammonium phosphate is used most frequently in agriculture as a component of fertilisers. It provides soil with nitrogen and phosphorus in a form that plants can use. Its NPK label reads 12-61-0 (12-27-0), which indicates that it contains 27% elemental phosphorous and 12% by weight of phosphorus pentoxide P2O5.
Urea
Urea is a source of Nitrogen, an essential nutrient crucial for crop growth and development. Due to its high N content (46%N), urea is the most significant nitrogenous fertiliser. Additionally, it is used in the manufacturing of polymers and as a nutritional supplement for livestock.
More than 90% of the urea produced for industrial usage worldwide is used as nitrogen-release fertiliser. [7] Of all the commonly used solid nitrogenous fertilisers, urea has the largest nitrogen concentration. Its transportation costs are therefore minimal relative to the nitrogen nutrition it contains. The most prevalent biuret contaminant, which hinders plant development, is found in synthetic urea. In the soil, urea decomposes to produce ammonium ions. The crop absorbs the ammonium through its own roots.
Calcium Ammonium Nitrate (CAN)
Calcium ammonium nitrate is naturally hygroscopic and can collect moisture from the air, it may be utilised in the soil even when there isn’t enough water. It comprises 13% Nitrate Nitrogen, which provides nutrients to plants right away, and the remaining 13% Ammonium Nitrogen, which provides food gradually until the crop is fully mature.
The main application for calcium ammonium nitrate is as fertiliser. CAN made for fertiliser includes around 8% calcium and 21-27% nitrogen. Because it lessens soil acidification than a number of popular nitrogen fertilisers, CAN is favoured for use on acidic soils. Where ammonium nitrate is prohibited, it is also employed in its place. Several fast cold packs substitute calcium ammonium nitrate for ammonium nitrate.
Limestone Ammonium Nitrate (LAN)
KAN / LAN (28) is a granular limestone ammonium nitrate (LAN) fertilizer that is primarily used on lawns. It is a high nitrogen fertilizer that feeds the plant’s leaves.
A common inorganic fertiliser, calcium ammonium nitrate (CAN), often known as nitro-limestone or nitrochalk, accounted for 4% of all nitrogen fertiliser used globally in 2007.
Ammonium Sulphate (AS21)
The inorganic salt ammonium sulphate, or (NH4)2SO4, is a significant source of sulphur (S) and nitrogen (N) for plant nutrition. It may be sprayed directly to plants, as well as used in compound fertilisers and NPK mixes.
Ammonium sulphate is mostly used as a fertiliser for alkaline soils. The ammonium ion is released in the soil and converts to a little quantity of acid, which lowers the pH equilibrium of the soil and provides necessary nitrogen for plant development. The biggest drawback of using ammonium sulphate is that it contains less nitrogen than ammonium nitrate, which raises transportation expenses. It is further employed as an agricultural spray adjuvant for fungicides, herbicides, and liquid insecticides. There, it serves to bind calcium and iron cations that are found in both plant cells and well waters.
Muriate Of Potash (MOP)
Potassium chloride sometimes referred to as muriate of potash contains 60% potash. Potassium is necessary for healthy plant development. It is essential for the synthesis of proteins and carbohydrates.
Potassium increases the thickness of the outer cell walls, which helps the plant withstand disease and promotes the formation of robust stems.
Di-Ammonium Phosphate (DAP)
Due to its high concentration of nitrogen and phosphorus, two of the 18 necessary plant nutrients and two of the main macronutrients, DAP is a favoured fertiliser in India. DAP (NH4)2HPO4: DAP for fertiliser Contains 46% phosphorus and 18% nitrogen (P2O5).
As fertiliser, DAP is employed. [4] When used as plant food, it temporarily raises the soil’s pH level but over time, nitrification of the ammonium causes the treated soil to become even more corrosive than it was before. Since its ammonia is much more prone to turn into ammonia in a high-pH atmosphere, it is unsuitable with alkaline substances.
