The prevention of water logging in the clayey soil is due to the presence of ____________

Options

A. organic matter
B. nitrogen
C. oxygen
D. phophorus

Explanation

**Step-by-Step Solution:**

1. **Understanding Waterlogging**: Waterlogging occurs when the soil is saturated with water, leading to poor drainage and affecting plant growth. It is particularly common in clayey soils due to their compact nature.

2. **Identifying the Role of Organic Matter**: Organic matter refers to decomposed plant and animal materials in the soil. It plays a crucial role in improving soil structure and drainage.

3. **Impact of Organic Matter on Clayey Soil**: In clayey soils, the presence of organic matter helps to create spaces between soil particles. This improves aeration and drainage, reducing the likelihood of waterlogging.

4. **Conclusion**: Therefore, the prevention of waterlogging in clayey soil is primarily due to the presence of organic matter.

**Final Answer**: The prevention of water logging in the clayey soil is due to the presence of **organic matter**.
