Good soil for gardens is often referred to as LOAM, which is a combination of clay, silt, and sand. LOAM is considered ideal for gardening because it has the right balance of nutrients, moisture, and air to support healthy plant growth. It also has good drainage and aeration, which helps to prevent waterlogging and root rot. LOAM is a popular choice for gardeners because it is easy to work with and can be amended with organic matter to improve its fertility.
