Urea Granular & Prilled GRANULAR UREA & PRILLED

Granular Urea
Urea Granular & Prilled It is White Crystalline solid containing 46% Nitrogen (N). It has the highest nitrogen content of any solid nitrogen fertilizer. Granular urea can be applied directly to the soil while using normal spreading equipment. Most of today's urea is manufactured as granules. Granules are harder, larger, and more resistant to moisture. Therefore, granulated urea has become a more commonly used material for fertilizer blends. Additionally, urea is an important raw material for many manufacturers of other products and is a major raw material for melamine.

The physical specification of Urea is non–clotted 100% free from harmful substances, free floating, treated with anti–caking treatment, free from impurities, sand, dust and certified non radioactive. PH value 8.0 to 8.5, float–ability/water sinks and mixes.

Urea, also known as Carbamide, is an organic compound with chemical formula CO(NH2)2. This amide has two -NH2 groups joined by a Carbonyl (C=O) functional group.

Urea Granular & Prilled Usage:

More than 90% of world industrial production of Urea is destined for use as a nitrogen–release fertilizer. Urea has the highest nitrogen content of all sold nitrogen content of all solid nitrogenous fertilizers in common use. Therefore, it has the lowest transportation costs per unit of nitrogen nutrition. The standard crop–nutrient rating of urea is 46-0-0. The most common impurity of synthetic urea is Biuret, which impairs plant growth.

Advantages of Urea Fertilizer

Urea is usually spread at rates of between 40 and 300 Kg./HA but rates vary. Smaller applications incur lower losses due to leaching. 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. The application equipment must be correctly calibrated and properly used.

Urea is chemically the same as Granular Urea. Its the most popular and economical of all nitrogenous fertilizers being used worldwide. The 46% nitrogen content of Urea is an ideal source of nitrogen for agriculture. Granular urea needs to be applied several times during the growing season, unlike phosphate and potassium fertilizers, which usually require a single application. Urea is an organic compound because it contains carbon. Prilled Urea is commonly used in agriculture as nitrogen rich filler.

Urea Ammonium Nitrate (UAN)

Urea Ammonium Nitrate is a liquid fertilizer solution. Fluid fertilizers are popular in many areas because they are safe to handle, convenient to mix with other nutrients and chemicals, and are easily applied. A solution of urea [CO(NH2)2] and ammonium nitrate [NH4NO3] containing between 28%, 30% and 32% nitrogen (N) is the most popular fluid N fertilizer.

Liquid Urea Chemical Structure of Urea Ammonium Nitrate (UAN)

Chemical Structure Urea Advantages of liquid fertilizer UAN:

1. It provides prolonged nutrition of plants with Nitrogen (N), allows you to adjust the nutrition in the key phases of plant growing, increase the missing factors in development, to obtain the necessary characteristics of commercial products (Protein, Gluten, Brewing Barley, etc.);
2. Has high application efficiency in all climatic zones, including "Dry";
3. The cost of nitrogen in UAN is lower, since nitrogen costs do not exceed 10% of total nitrogen when UAN is applied, while 30 to 40% when applying granular Nitrogen Fertilizers;
4. UAN application as liquid fertilizers is more even than it is possible for solid and granular;
5. Reduces technological costs, due to the possibility of combining UAN introduction in a mixture with pesticides and other liquid mineral fertilizers (in the first place, with micro-nutrients);
6. It is possible to use for fractional fertilizing of vegetative plants. At the same time, root and foliar top feeding can take place;
7. UAN 32 is non-toxic, non–flammable and not-explosive, does not pollute the environment. Due to the lack of free ammonia in the UAN, it does not evaporate into the atmosphere; and
8. Can be transported in any capacity – Plastic, Stainless, Carbon Steel.

Liquid Fertilizer Urea Difference Between Fertilizer and Manure

Timing of usage:

1. In the Autumn - it is used for basic processing;
2. In the Spring - it is used under sowing treatment;
3. During the growing season of crops for foliar (Leaf) and root nutrition.

DIAMMONIUM PHOSPHATE (DAP)

Diammonium Phosphate (DAP) 18-46-0 (Chemical Formula (NH4)2HPO4, IUPAC name Diammonium Hydrogen Phosphate). It is one of a series of water soluble Ammonium Phosphate Salts. It produces when Ammonia reacts with Phosphoric Acid.

DAP Production:

Diammonium Phosphate fertilizers first became available in the 1960s. DAP rapidly became the most popular in this class of products. It’s formulated in a controlled reaction of Phosphoric Acid with Ammonia. The hot slurry is then cooled, granulated and sieved. DAP handles and stores well. The standard nutrient grade of DAP is relatively high, at 18-46-0, so fertilizer products with lower nutrient content may not be labeled DAP. The high nutrient content of DAP helps reduce handling, freight and application costs. DAP is produced in many loactions in the world and it is widely traded fertilizer commodity.

Chemical Structure of DiAmmonium Phosphate (DAP)

Chemical Structure of DAP DiAmmonium Phosphate Uses:

Diammonium Phosphate (DAP) is used as a fertilizer. When applied as plant food, it temporarily increases the soil PH, but over a long term the treated ground. It becomes more acidic than before upon nitrification of the ammonium. It is incompatible with alkaline chemicals because its ammonium ion is more likely to convert to ammonia in a high–pH environment. The average pH in solution is 7.5–8. The typical formulation is 18-46-0 (18% N, 46% P2O5, 0% K2O).

DAP can be used as a fire retardant. It lowers the combustion temperature of the material, decreases maximum weight loss rates. It also causes an increase in the production of residue or char. These are important effects in fighting wildfires as lowering the pyrolysis temperature and increasing the amount of char formed reduces that amount of available fuel and can lead to the formation of a firebreak. It is the largest component of some popular commercial firefighting products.

DAP is also uses in various industries like:

* As a yeast nutrient in wine making and mead brewing;
* Also as an additive in some brands of cigarettes purportedly as a nicotine enhancer;
* It prevents afterglow in matches, in purifying sugar;
* To use as a flux for soldering tin, copper, zinc and brass; and
* To control precipitation of alkali-soluble and acid-insoluble colloidal dyes on wool.

Monoammonium Phosphate (MAP)

MAP Monoammonium Phosphate (MAP) 11-52-0 is a widely used source of phosphorus (P) and nitrogen (N). It's made of two constituents common in the fertilizer industry and contains the most phosphorus of any common solid fertilizer. MAP's manufacturing process is relatively simple. The most common fertilizer composition is 11-52-0. MAP has been an important granular fertilizer for many years. It's water-soluble and dissolves rapidly in adequately moist soil. Ammonium dihydrogen phosphate (ADP), also known as monoammonium phosphate (MAP) is a chemical compound with the chemical formula (NH4)(H2PO4). ADP is a major ingredient of agricultural fertilizers[6] and some fire extinguishers. It also has significant uses in optics and electronics.

Chemical Properties
MAP Monoammonium phosphate is soluble in water and crystallizes from it as the anhydrous salt in the tetragonal system, as elongated prisms or needles. It is practically insoluble in ethanol. Solid monoammonium phosphate can be considered stable in practice for temperatures up to 200 °C, when it decomposes into gaseous ammonia NH 3 and molten phosphoric acid H3PO. At 125 °C the partial pressure of ammonia is 0.05 mm Hg.[10] A solution of stoichometric monoammonium phosphate is acidic (pH 4.7 at 0.1% concentration, 4.2 at 5%).

Preparation
Monoammonium phosphate is industrially prepared by the exothermic reaction of phosphoric acid and ammonia in the correct proportions Crystalline MAP then precipitates.

Uses

Agriculture
The largest use of monoammonium phosphate by weight is in agriculture, as an ingredient of fertilizers. It supplies soil with the elements nitrogen and phosphorus in a form usable by plants. Its NPK label is 12-61-0 (12-27-0), meaning that it contains 12% by weight of elemental nitrogen and (nominally) 61% of phosphorus pentoxide P2O5, or 27% of elemental phosphorus.

Fire extinguishers
The compound is also a component of the ABC powder in some dry chemical fire extinguishers.

Optics
Monoammonium phosphate is a widely used crystal in the field of optics due to its birefringence properties. As a result of its tetragonal crystal structure, this material has negative uniaxial optical symmetry with typical refractive indices no = 1.522 and ne = 1.478 at optical wavelengths.

Electronics
Monoammonium phosphate crystals are piezoelectric, a property required in some active sonar transducers (the alternative being transducers that use magnetostriction). In the 1950s ADP crystals largely replaced the quartz and Rochelle salt crystals in transducers because they are easier to work than quartz and, unlike Rochelle salt, are not deliquescent.
