Urea, also called carbamide, is an organic compound with chemical formula CO(NH2)2. This amide has two amino groups joined by a carbonyl functional group. It is thus the simplest amide of carbamic acid.
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 macro nutrients: 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.
Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH4)2(HPO4) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid.
Struvite (magnesium ammonium phosphate) is a phosphate mineral with formula: NH4MgPO4·6H2O. Struvite crystallizes in the orthorhombic system as white to yellowish or brownish-white pyramidal crystals or in platy mica-like forms. It is a soft mineral with Mohs hardness of 1.5 to 2 and has a low specific gravity of 1.7. It is sparingly soluble in neutral and alkaline conditions, but readily soluble in acid.
The Fertilisers and Chemicals Travancore Limited, abbreviated as FACT, is an Indian central public sector undertaking headquartered in Kochi, Kerala. It was incorporated in 1943, by Maharajah Sree Chithira Thirunal Balarama Varma of the Kingdom of Travancore. It is the first fertiliser manufacturing company in independent India and also the largest Central Public Sector Undertaking (CPSU) in Kerala. The company is under the ownership of Government of India and administrative control of the Ministry of Chemicals and Fertilizers.
Urea phosphate is a fertilizer having NPK formula 17-44-0. It is soluble in water, and produces a strongly acidic solution. Urea phosphate is sometimes added to blends which contain calcium nitrate, magnesium nitrate and potassium nitrate to produce water-soluble formulas such as 15-5-15 and 13-2-20. The acidity of urea phosphate allows Ca, Mg and P to co-exist in solution. Under less acidic conditions, there would be precipitation of Ca-Mg phosphates. Urea phosphate is often used in drip irrigation to clean pipe systems.
Krishak Bharati Cooperative Limited (KRIBHCO) is a Central government cooperative under the ownership of Ministry of Cooperation, Government of India that manufactures fertilizers, mainly urea.
The OCP Group is a state-owned phosphate rock miner, phosphoric acid manufacturer and fertilizer producer. Founded in 1920, the company has grown to become the world's largest producer of phosphate and phosphate-based products and it is one of the largest phosphate, fertilizer, Chemicals and Mineral industrial companies in the world by revenue.
National Fertilizers Limited (NFL) is an Indian central public sector undertaking and the largest government-owned-Urea fertilizer-producer in India as of 2022. It is a Miniratna (Cat-1) company, with the Government of India owning a majority stake.
Indian Farmers Fertiliser Cooperative Limited, also known as IFFCO, is a multi-state cooperative society. IFFCO is wholly owned by Cooperative Societies of India. The society is engaged in the business of manufacturing and marketing of fertilizers. IFFCO is headquartered in New Delhi, India. Started in 1967 with 57 member cooperatives, it is today the biggest co-op in the world by turnover on GDP per capita, with around 35,000 member cooperatives reaching over 50 million Indian farmers.
Tata Chemicals Limited is an Indian global company with interests in chemicals, crop protection and specialty chemistry products headquartered in Mumbai, India. The company is one of the largest chemical companies in India with operations in India, Europe, North America and Africa. Tata Chemicals is a subsidiary of the Tata Group. Tata Chemicals has a publicly listed subsidiary called Rallis India.
A controlled-release fertiliser (CRF) is a granulated fertiliser that releases nutrients gradually into the soil. Controlled-release fertilizer is also known as controlled-availability fertilizer, delayed-release fertilizer, metered-release fertilizer, or slow-acting fertilizer. Usually CRF refers to nitrogen-based fertilizers. Slow- and controlled-release involve only 0.15% of the fertilizer market (1995).
Heavy Water Board (HWB) is a constituent unit under the Department of Atomic Energy in the Government of India. The organisation is primarily responsible for production of heavy water (D2O) which is used as a moderator and coolant in nuclear power as well as research reactors. Other than heavy water, the HWB is also engaged with production of nuclear grade solvents and extraction of rare materials. India is one of the largest manufacturers of heavy water in the world. Similarly, India has one of the world's largest fleets of pressurized heavy water reactors producing most of India's nuclear power supply.
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 and some fire extinguishers. It also has significant uses in optics and electronics.
Rashtriya Chemicals & Fertilizers Ltd. (RCF) is an Indian central public sector undertaking which produces chemical and fertilizers and is based in Mumbai. It is under the ownership of Government of India and administrative control of Ministry of Chemicals and Fertilizers. RCF is fourth largest government owned-fertilizer-producer in India.
Commodity chemicals are a group of chemicals that are made on a very large scale to satisfy global markets. The average prices of commodity chemicals are regularly published in the chemical trade magazines and web sites such as Chemical Week and ICIS. There have been several studies of the scale and complexity of this market for example in the USA.
Joint-stock company "Lifosa" is Lithuanian phosphate industry company, situated in Kėdainiai, the geographical center of Lithuania. AB "Lifosa" is one of the biggest producers of fertilizers in the Eastern Europe, exporting more than 98% of its production. The products are exported to 40-45 countries annually on all continents except Australia. The company also produces heat and power. Most of the produced energy is consumed by the company, the rest of the energy is sold. During the utilization of the heat generated by the production of sulfuric acid, a total of about 100 thousand MWh of the heat energy can be supplied to the city of Kėdainiai or about 250 mln. kWh of electricity can be produced.
Yeast assimilable nitrogen or YAN is the combination of free amino nitrogen (FAN), ammonia (NH3) and ammonium (NH4+) that is available for a yeast, e.g. the wine yeast Saccharomyces cerevisiae, to use during fermentation. Outside of the fermentable sugars glucose and fructose, nitrogen is the most important nutrient needed to carry out a successful fermentation that doesn't end prior to the intended point of dryness or sees the development of off-odors and related wine faults. To this extent winemakers will often supplement the available YAN resources with nitrogen additives such as diammonium phosphate (DAP).
