What is manure class 9 science
Manure is an organic matter derived from the decomposition of animal waste, plant materials, and other natural substances. It is often used in agriculture to enrich soil. By improving the physical and chemical properties of soil, manure promotes healthy plant growth and increases crop yields. Manure can take various forms, including solid, liquid, and composted materials.
Types of Manure
There are primarily two types of manure: farmyard manure and green manure. Farmyard manure consists of animal waste mixed with bedding materials like straw and hay. It is rich in nutrients, especially nitrogen, phosphorus, and potassium. Green manure, on the other hand, involves growing certain plants, like legumes, which are then plowed back into the soil. This practice not only adds nutrients but also enhances soil structure.
