What term describes animal droppings used to fertilize land?

• A. Fertilizer
• B. Soil Exhaustion
• C. Irrigation
• D. Manure

Answer: (D)

Manure is animal droppings used as a fertilizer. It provides nutrients to the soil as it decomposes and adds organic matter, which helps plants grow and improves soil structure, porosity, and moisture retention. Manure releases essential nutrients like nitrogen, phosphorus, and potassium back into the soil, supporting crop growth in a natural way. It’s a traditional, natural source of fertility and recycles livestock waste. Proper handling, such as aging or composting, helps reduce risks from pathogens and weed seeds and prevents potential nutrient burn. The other terms refer to different ideas: irrigation is about watering, soil exhaustion describes a decline in soil fertility, and fertilizer is a general term for any substance that supplies nutrients (manure is a natural example of this).
