Read the following passage and answer the next five questions:(28-32)

In our quest to increase agricultural production during the last five decades or so, we almost totally neglected the use of compost and completely switched over to chemical fertilizers. The result is that large tracts of productive land have been adversely affected, water bodies including ground water system have suffered due to chemical contamination and demand for irrigation has been going up year after year. Farmers, in large numbers all over the country, have again started using compost made from organic wastes of different types. In certain parts of the country, cattle are maintained only because they produce dung which is an important fertilizer and soil conditioner. Earthworms can convert organic matter into compost faster than the normal composting pro cess. This process is now being widely used. Indirectly, the civic authorities are benefitted too as they have to dispose reduced quantity of waste.

What should be the suitable title for the above passage?

The correct option is Biocomposting.

Step-by-Step Explanation:

1. Analyze the Core Theme of the Passage:
The passage discusses the transition of agricultural practices from chemical fertilizers back to organic methods due to the negative impacts of chemicals on land and water. Specifically, it highlights the reuse of organic wastes, cow dung, and the accelerated conversion of organic matter into compost using earthworms (a process commonly known as vermicomposting or biocomposting).

2. Evaluate the Options:
- Biopest Control: The passage does not mention pests, insects, or methods to control them.
- Traditional Knowledge and Practice: While the passage mentions farmers returning to organic waste and cattle dung, the primary scientific and modern process highlighted at the end is the acceleration of composting using earthworms.
- Uses of Chemical Fertilizers: The passage only mentions the negative consequences of chemical fertilizers, not their active uses or benefits.
- Biocomposting: This term directly represents the process of biological composting using organic waste, cattle dung, and biological agents like earthworms to create soil conditioners, which is the central solution and focus of the passage.

3. Conclusion:
Since the main focus of the text is on creating compost from organic wastes and utilizing earthworms to speed up the composting process to restore soil health, "Biocomposting" serves as the most accurate and suitable title.
