What type of organic waste can be used to improve soil fertility?

Manure and compost are types of organic waste that significantly contribute to improving soil fertility. Both materials are rich in essential nutrients such as nitrogen, phosphorus, and potassium, which are crucial for plant growth. When applied to the soil, they enhance the organic matter content, promoting better soil structure, water retention, and microbial activity, all of which are vital for a healthy growing environment.

Compost is particularly beneficial as it is created through the decomposition of various organic materials, which may include food scraps, garden waste, and even some types of manure. This process not only sequesters nutrients but also stabilizes them, making them more available to plants over time.

While grass clippings, leaves, and food scraps also contribute to soil fertility, they are typically considered more specific examples or ingredients in the larger category of compost rather than standalone solutions like manure and compost itself. Plastic waste does not contribute positively to soil fertility; rather, it can lead to pollution and adverse environmental effects. Thus, the combination of manure and compost represents a comprehensive approach to enriching soil fertility effectively.
