Loam

Loam is a type of soil that consists of sand, silt, and clay in balanced proportions. Loam is considered ideal for gardening and agriculture because it retains nutrients and moisture well, but also allows excess water to drain. Loam also contains humus, which is organic matter that improves soil fertility and structure. Loam soils can vary in texture and composition, depending on the ratio of sand, silt, and clay particles.
