1. What is manure and why is it important for agriculture?
Ans. Manure is organic matter, such as animal waste or decaying plant material, used as fertilizer in agriculture. It is important because it provides essential nutrients to the soil, improves soil structure and water-holding capacity, promotes microbial activity, and enhances crop growth and yield.
2. How is manure produced and collected?
Ans. Manure is produced by the decomposition of organic matter, such as animal waste and plant residues. It can be collected from livestock farms, poultry farms, or by composting organic waste materials. Collection methods vary, but commonly involve storing manure in pits, tanks, or composting piles.
3. What are the different types of manure?
Ans. There are several types of manure, including cow manure, horse manure, pig manure, poultry manure, and composted manure. Each type has different nutrient compositions and characteristics, which can affect its suitability for specific crops or soil types.
4. How is manure applied to crops?
Ans. Manure can be applied to crops through various methods, such as broadcasting, topdressing, side-dressing, or incorporation into the soil. The application method depends on the type of manure, crop type, and farming practices. It is important to apply manure in appropriate quantities to avoid nutrient imbalances and environmental pollution.
5. What are the benefits of using manure in organic farming?
