Compost is organic matter in which a certain sets of microorganisms have grown aerobically and in the process have released metabolic heat and metabolic products, which are useful to plants and maintain the microbial life in the soil.
By application of compost, we inoculate the soil with a diversity of microorganisms and create a healthy food web within that soil.
Good compost does two things in the soil:
- Add diversity of microorganisms
- Provide readily available food for plants and the microorganisms
Based on the process used to make it, compost can be of three kinds:
- Thermal compost
- Vermicompost or worm compost
- Static-pile compost
