To determine which soil sample has a texture that is high in sand, we need to look at the descriptions of the soil samples provided and identify which characteristics match those typically associated with sandy soil.
Let's examine each soil sample's description:
- Sample A: Smallest particle size, water doesn't drain well
- This description matches clay soil, which has fine particles and poor drainage.
- Sample B: Medium particle size, holds water well
- This description matches loam or silt, which has intermediate particle size and good water retention.
- Sample C: Coarse particles, loose soil, water drains quickly
- This description matches sandy soil, which has larger particles, is loose, and tends to allow water to drain quickly.
- Sample D: Mixture of particle sizes, contains humus
- This description matches loam soil, which has a balance of sand, silt, and clay particles and contains organic matter.
From these descriptions, it is evident that Sample C, with coarse particles, loose soil, and rapid water drainage, is indicative of sandy soil.
Therefore, the soil sample that has a texture high in sand is:
Sample C
