A quality of richness in soil that has nearly equal amounts of clay, silt, and sand with humus, an organic substance consisting of decayed plat materials. Humus is the element that makes loamy soil incredibly fertile. This mix of sand, clay, silt, and humus causes the soil to be crumbly and prone to retain moisture.
