RCF manufactures Urea and Complex fertilizers (NPK) along with a wide range of Industrial Chemicals. It is 4th largest Urea manufacturer in India after IFFCO, NFL and KRIBHCO. [5]
The N value in NPK labels represents actual percentage of nitrogen element by weight, so it does not need to be converted. So, for example, an 18−51−20 fertilizer contains by weight 18% elemental nitrogen, 0.436 × 51 = 22% elemental phosphorus, and; 0.83 × 20 = 17% elemental potassium.

The filtrate is composed mainly of phosphoric acid with some nitric acid and traces of calcium nitrate, and this is neutralized with ammonia to produce a compound fertilizer. Ca ( NO 3 ) 2 + 4 H 3 PO 4 + 8 NH 3 CaHPO 4 + 2 NH 4 NO 3 + 3 ( NH 4 ) 2 HPO 4 {\displaystyle {\ce {Ca(NO3)2 + 4 H3PO4 + 8 NH3 -> CaHPO4 + 2 NH4NO3 + 3(NH4)2HPO4}}}
FDP involves "briquetting" nitrogen fertilizer by compacting prilled fertilizer into 1-3 gram briquettes. The briquettes (either urea- or NPK-based) are then placed in a plant's root zone, as opposed to the traditional application method of broadcasting. Trials have shown that FDP and UDP (when only urea is used) can increase crop production up ...
Urea phosphate is a 1:1 combination of urea and phosphoric acid that is used as a fertilizer. It has an NPK formula of 17-44-0, [ 1 ] and is soluble in water, producing a strongly acidic solution. Urea phosphate is available in fertilizer vendor bags that carry a UP signet on the packaging.
