What is animal dung used as fertilizer commonly called?

Animal dung used as fertilizer is commonly referred to as manure. This term specifically describes animal excreta that is utilized to enrich soil and improve its fertility. Manure is high in nutrients such as nitrogen, phosphorus, and potassium, which are essential for plant growth. Using manure as fertilizer helps in enhancing soil structure, increasing its water retention capacity, and promoting microbial activity, all of which contribute to healthier crop production.

Compost, while also a type of organic matter used to enhance soil, typically involves decayed plant material rather than animal waste. Organic waste refers to any biodegradable waste, which can include food scraps or yard waste, but is broader and not specifically linked to animal dung. Biomass encompasses any type of biological material that can be used for energy or as raw material, not necessarily related to fertilization or animal dung. Therefore, the specificity of manure to animal dung clearly identifies it as the correct answer.
