 An organic material used as a natural fertilizer to enrich the nutrients of soil and promote plant growth is Manure.  It primarily or mainly consists of animal waste (like cow dung, horse manure, poultry droppings) mixed with bedding materials such as straw or hay. Manure provides essential nutrients like nitrogen, phosphorus, and potassium to the soil, improving its fertility and structure. Types of Manure:__ 1. Green Manure: This type of manure is made by growing and plowing under specific plants (e.g., legumes) to improve soil fertility. 2. Animal Manure: This kind of manure is produced from livestock waste, commonly used in farming. 3. Compost Manure: This kind of manure is made by decomposing organic household and garden waste into nutrient-rich humus. Benefits of Manure are as follows:__ __It enhances structure of soil by improving aeration and drainage. __It provides essential nutrients for plant growth. __It encourages microbial activity in the soil, making nutrients...
