Organic fertilizers are ideal for any garden. But we resort to chemical fertilizers as we have no unique idea about these organic fertilizers. But regular use of these chemical fertilizers can harm both plants and soil. Avoiding these harmful chemical fertilizers as much as possible, using organic fertilizers can improve both the ground and the plants. Organic fertilizers not only improve plants and soil, but they can help also regulate the entire ecosystem.

Keeping this concept in mind, the names of 36 types of organic fertilizers and their brief descriptions are given below so that organic processing can be promoted more.
