Which soil texture group includes sandy loam and loam soil textural classes?

Explanation:
Soil texture groups are built from how sand, silt, and clay combine to form texture classes. Sandy loam and loam are mid-range textures—they’re not as coarse as sandy soils and not as fine as heavy clay soils. That puts them in the middle of the texture spectrum, which is the medium-texture group. Soils in this group typically balance drainage with moisture retention, a practical fit for septic system considerations. The other groups cover textures at the extremes—coarser ones that drain very quickly and finer, clayey ones that hold water—so they don’t include sandy loam or loam.
