Nitrogen Phosphate – Potash (Nkp) Fertilizer Production
Many fertilizing materials are used in the production of NKP fertilizer, which supplies the necessary element plants.
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.
MURIATE OF POTASH NPK (0:0:60)
Muriate of potash is prepared industrially from sylvinite and carnanlite by using special additive which usually makes muriate of potash crystals hydrophobic, so that they are carried upwards to float occluded. This material contains grand formular NPK (0:0:60) which means that it has 0% of Nitrogen, 0% of phosphate and 60% of potassium.
PROPERTIES OF MURIATE OF POTASH FERTILIZER
- It is reddish in colour
- Muriate of potash is dust
- It attacks skin and ferrous materials
- It has a granular shape.
BIOLOGICAL FUNCTIONS OF MURIATE OF POTASH
- It helps during photosynthesis in plants.
- Muriate of potash is also used in medicine and food processing.
Diammonium phosphate is one of the fertilizering materials that contain nitrogen and phosphorous with a grand formular of NPK (18:46:0). This implies that it has 18% of nitrogen 46% of phosphorus and 0% of potassium. Diammonium phosphate is stored in cool and dry place to avoid decomposition to the monoammonium salt. This material is less acidic to other materials.
PROPERTIES OF DIAMMONUIM PHOSPHATE
- The materials is greenish in colour
- It is dusty
- It is neutral with a pH level of 7
- It emits gas
BIOLOGICAL FUNCTIONS OF DIAMMONIUM PHOSPHATE
- It helps to strengthen growing plants.
CALCIUM TRIOXOCARBONATE (IV) NPK (0:0:0) (LIMESTONE)
This is a grayish granular solid that occurs naturally as chalk, marble as in natural ores likes calcite. This material has a grand formular NPK (0:0:0) which means it has 0% of nitrogen, 0% of phosphate and 0% potassium. The company uses it as their filler because of its function to the soil. Limestone reduces the acidity of the soil. It is stored in cool and dry place.
PROPERTIES OF LIMESTONE
- The material is grayish in colour
- It is dusty
- It is neutral with pH level of 7
- It has a gramular shape.
BIOLOGICAL FUNCTION OF LIMESTONE
- Control leaching
- It reduces soil acidity
- Limestone assists the soil to release some of its natural nutrients
