To determine which soil sample has a soil texture that is high in sand, we need to analyze the descriptions given for each sample and identify the characteristics that match those of sandy soil.
1. Sample A:
- Description: Smallest particle size, water doesn't drain well.
- Analysis: Soil with the smallest particle size is generally clay. Clay has tiny particles that are packed tightly together, which prevents water from draining well. Sandy soil, on the other hand, has larger particles and drains quickly. Thus, Sample A is not high in sand.
2. Sample B:
- Description: Medium particle size, holds water well.
- Analysis: Soil with medium particle size is typically loam. Loam holds water better than sandy soil but less than clay. Loam is known for being very fertile and good at retaining moisture without becoming waterlogged. Hence, Sample B is not high in sand.
3. Sample C:
- Description: Coarse particles, loose soil, water drains quickly.
- Analysis: Sandy soil is known for having coarse particles. This type of soil is loose, and water drains through it rapidly. The description of Sample C matches these characteristics, indicating that it is high in sand.
4. Sample D:
- Description: Mixture of particle sizes, contains humus.
- Analysis: This description suggests a soil type that is well-balanced and contains organic matter (humus). This type of soil is often good for plant growth but is not specifically high in sandy content. Therefore, Sample D is not high in sand.
Based on the descriptions provided, the soil sample with a high sand content and the characteristics of sandy soil (coarse particles, loose soil, and quick drainage) is Sample C.
Therefore, the correct answer is Sample C.
