Explanation:
Fertilizers
Fertilizers are natural or synthetic materials that we add to the soil to provide the plants with the nutrients they need. They can be organic or inorganic in nature. They work by providing plants and crops with nutrients they need to grow to their fullest and at a faster rate than attained via a natural process. Chemical-based fertilizers also act as an insecticide, protecting plants from pests and insects.
Manure
Manure is a natural fertilizer. To make manure, decomposition of plants and animal waste is done by farmers. The product of this decomposition is a material rich in organic matter which we call manure. Manure does not have a high content of nutrients. Instead, it gives fertility to the soil by adding humus (organic component of the soil). This improves the soil’s physical properties, with better retention of moisture and more aeration.
