Loam (in geology and soil science) is soil composed mostly of sand (particle size > 63 micrometres (0.0025 in)), silt (particle size > 2 micrometres (7.9×10 in)), and a smaller amount of clay (particle size < 2 micrometres (7.9×10 in)). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in dif… WebThe texture is important to overall soil and plant health as it relates to soil porosity, which refers to the pore spaces where air and water reside.
