MATERIALS USED IN THE PRODUCTION OF NITROGEN PHOSPHATE – POTASH (NKP) FERTILIZER
The company uses four materials which includes urea, muriate of potash Diammonium phosphate and calcium carbonate, (Limestone) known as the filler in the production of NPK fertilizer some other industries uses sea sand as their filler like Enugu State Fertilizer Company. This materials are handled properly to avoid destruction in other to maintain the quality control.
They are stored in a cool and dry place to prevent moisture and dissolution before blending. Examples of the fertilizing materials used in the factory includes,
UREA NPK 46:0:0
Urea is a white crystalline solid with chemical formular (NH2) Co. It has a low density and melting point of 132C. This material has a grand formular NPK (46:0:0) which means that it has 46% of Nitrogen 0% of phosphorus and 0% of potassium. This material is imported into the company from accredited dealers.
This material can be hydrolyzed red to from ammonia and carbon oxide by the action of an enzyme called urease.
CO (NH2)2+H2O 2NH3+CO2 Urea is preferred in the production of Nitrogen-phosphate –potash fertilizer because it has high content of Nitrogen more than other chemicals such as NH4 CL2 (NH4)2 SO4 and CaNo3 etc. Urea in stored in a cool and dry place to avoid dissolution.
PROPERTIES OF UREA
- It is whitish in colour
- It is corrosive
- It emits fumes and gas and
- Urea attacks skin and ferrous materials
BIOLOGICAL FUNCTIONS OF UREA
- It is applied in the synthesis of resins
- It is used in cattle feed-stuffs as an integrator in the production pharmaceutical explosive
- It helps in the growth of plant and crops like rice.
It releases nitrogen to the plants.
