What are the two types of Class II soils?

Class II soils are typically characterized by their moderate limitations for certain uses, including construction and agricultural purposes. The correct answer, which identifies sandy loam and loam as the two types of Class II soils, reflects their properties that often allow for better drainage and root penetration compared to other types of soil with higher clay content. Sandy loam contains a mix of sand, silt, and a small amount of clay, which enhances aeration and water retention. Meanwhile, loam, which is also a balanced mixture of sand, silt, and clay, offers ideal conditions for plant growth, making them suitable for agricultural use.

The other options do not correctly represent Class II soils. Sandy loam and clay do not fit well together in this classification due to the heavy nature of clay, which is more prone to compaction and poor drainage. Silt loam and sand do not provide the same balanced properties as a loam soil, and clay and silt, while they may have some utility, do not align with the characteristic benefits of Class II soils essential for agricultural and construction practices.
