Question

Explain the difference between chemical fertilizer and biofertilizer.

Hint:

Over-reliance on chemical fertilizers can degrade soil health, whereas biofertilizers help maintain long-term soil fertility.

Answer 1

Step 1: Chemical Fertilizer.
Chemical fertilizers are man-made substances that are applied to plants to supply essential nutrients like nitrogen, phosphorus, and potassium. They are usually synthetic and provide quick-release nutrients to plants. However, excessive use can harm the soil, cause pollution, and disrupt the ecosystem.
Step 2: Biofertilizer.
Biofertilizers are natural fertilizers that contain living microorganisms. These microorganisms help enhance the nutrient supply to plants by improving soil fertility and increasing the availability of nutrients. Examples of biofertilizers include Rhizobium (which helps fix nitrogen) and Azotobacter.
Step 3: Differences Between Chemical Fertilizer and Biofertilizer.
1. Source: Chemical fertilizers are synthetic, while biofertilizers are natural. 2. Impact on Soil: Chemical fertilizers can degrade soil quality, while biofertilizers improve soil health. 3. Nutrient Release: Chemical fertilizers provide immediate nutrient release, whereas biofertilizers work gradually by enhancing microbial activity in the soil.
Step 4: Conclusion.
Thus, while chemical fertilizers offer quick results, biofertilizers are more sustainable and environmentally friendly.
Final Answer: \[ \boxed{\text{Chemical fertilizers are synthetic, while biofertilizers are natural and improve soil health.}} \]
