Manure is obtained by decomposition of waste products of plants, animals and other natural materials in fields which make it rich in organic matter. Fertilizers are the inorganic chemical substances that serve as source of nitrogen, phosphorus and potassium and lack organic matter.
Fertilizers are produced in factories. Since, manure consists of nutrients in small quantities, large servings of manure is required by plants.
