Which soil group is associated with Sandy Clay Loam / Silt Loam / Clay Loam / Silty Clay Loam / Silt?

In this topic, how quickly the soil drains is the deciding factor for grouping. Soils with textures like Sandy Clay Loam, Silt Loam, Clay Loam, Silty Clay Loam, and Silt have finer particles and smaller pore spaces, so water moves through them more slowly than through sandy soils. That slower drainage places them in the group that corresponds to slow infiltration and more limitations for septic systems. So, these textures are associated with Soil Group III. The other groups cover soils with faster drainage or more severe limitations, which doesn’t fit these textures as well.
