Loam soil contains the highest amount of humus compared to clay and sand. Loam is a balanced mixture of clay, silt, and sand, and it typically retains moisture well while also having good drainage. The presence of organic matter, or humus, in loam improves its fertility and structure, making it ideal for growing a variety of plants. While clay can also contain humus, it tends to retain more moisture and can become compacted, while sand has very little humus and drains quickly.
