Compost ingredients include loams, which are a combination of clay, silt, and sand particles. Loams are often used in gardening and farming as they provide good drainage and aeration for plants. Composting is the process of breaking down organic matter into a nutrient-rich soil amendment that can be used to improve soil fertility. Composting ingredients can include food scraps, yard waste, and other organic materials. The combination of these materials helps to create a rich, nutrient-rich soil amendment that can be used to improve soil fertility and promote healthy plant growth.
