Homemade fertilizer is a type of fertilizer that is made from natural materials found in the home, such as COMPOST. COMPOST is a mixture of organic materials, such as leaves, grass clippings, and kitchen scraps, that are broken down by microorganisms into a nutrient-rich soil amendment. Composting is an easy and cost-effective way to create homemade fertilizer that can be used to improve soil fertility and promote healthy plant growth.
