The fertilizers prepared by mixing different types of chemical substances are called inorganic fertilizers. Especially, urea, potassium, ammonium phosphates, superphosphate are present in inorganic fertilizer. It is also known as commercial fertilizer or mineral. It is artificial fertilizer which is made by man. It provides nutrients for the growth and development of plants. so it is called complete fertilizers. It protects plants from insects and plant diseases. they provide nothing for the soil, limiting their effectiveness in the long-term. There is also the very real risk of a toxic overdose of chemicals that leach arsenic, cadmium, and uranium into the soil, potentially affecting any growing fruits or vegetables. They can easily upset the entire ecosystem, create a toxic buildup of chemicals, and long-term use changes the pH of the soil, increases a pest problem, and releases greenhouse gases. Greenhouse gases are raising the temperature of the Earth, causing climate change.
Advantages of inorganic fertilizer are as follows:
- It helps to revive the dying plant immediately.
- Inorganic fertilizers are soluble in water so plants absorb properly.
- It increases the fertility of the oil.
- The special type of nutrients is present in inorganic fertilizer.
- It is easier to transport.
Disadvantages of inorganic fertilizer are as follows:
- It is a higher cost than organic fertilizer.
- It causes the problem of leaching, i.e. the fertilizer and the nutrients getting washed away,
- It affects the soil structure.
- If the dose is high in the plant than whole plants and crops are burnt and destroyed.
- Accumulation of toxic wastes.
