Manure is commonly used as

• A. Fertilizer
• B. Fuel
• C. Bedding
• D. Food supplement

Answer: (A)

Manure is used as a fertilizer because it returns essential plant nutrients and organic matter to the soil, supporting crop growth and soil health. It supplies key nutrients such as nitrogen, phosphorus, and potassium, and adds organic matter that improves soil structure, water-holding capacity, and microbial activity. When manure is applied to fields or pastures in appropriate amounts and often after aging or composting, it provides a slow-release nutrient source and recycles nutrients that crops have taken up, which is a central practice in sustainable livestock and crop farming. Managing timing and rates is important to avoid nutrient runoff or pollution.

Other options aren’t the typical use. While manure can be processed for energy in biogas systems, and some waste products may play other roles, manure is most commonly used to fertilize soil. It isn’t used as bedding or as a food supplement in standard farming practices.
