A mixture of decayed matter is known as humus or compost. These terms refer to the organic material that is formed from the decomposition of plant and animal matter. Found in top layers of soils, hummus is a vital component that is essential for the fertility and structure of the soil. It can also be created through composting where organic waste like food scraps and garden clippings are broken down by microorganisms into nutrient-rich soil that is beneficial for plant growth.
