Which soil texture group includes silt and silt loam?

• A. Soil Group I - Sandy texture soils
• B. Soil Group II - Coarse loamy texture soils
• C. Soil Group IV - Clayey texture soils
• D. Soil Group III - Fine loamy texture soils

Answer: (D)

Understanding soil texture groups starts with particle size. Silt and silt loam have fine particles, giving them a finer texture that sits with the fine-textured soils rather than the coarse sandy or heavy clayey categories. Among the options, the group that includes loams with a finer texture—such as silt loam and other fine-loam textures—fits best. So, soils dominated by silt and those that are silt loam belong in the fine loamy texture soils group.
