Soil particles determine its

Options

A. texture
B. field capacity
C. water holding capacity
D. soil flora

Explanation

**Step-by-Step Solution:**

1. **Understanding Soil Particles**: Soil is made up of different types of particles, including sand, silt, and clay. The size and arrangement of these particles influence various soil properties.

2. **Identifying the Options**: The options given are:
- Texture
- Field capacity
- Water holding capacity
- Soil flora

3. **Defining Soil Texture**: Soil texture refers to the relative proportions of different soil particles (sand, silt, and clay) in a given soil sample. It is a critical property that affects how soil behaves.

4. **Understanding Pore Space**: Pore space is the space between soil particles. It is important for water retention and air circulation within the soil. The size of the pore spaces can vary depending on the texture of the soil.

5. **Analyzing the Relationship**: Fine-textured soils (like clay) have smaller pore spaces but a higher frequency of pores, while coarse-textured soils (like sand) have larger pore spaces but fewer pores. This directly relates to the soil's texture.

6. **Conclusion**: Since soil particles determine the arrangement and size of the pore spaces, which in turn defines the texture of the soil, the correct answer to the question is "texture."

**Final Answer**: Soil particles determine its texture.
