Question

Soil particles determine its

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

Answer 1

The Correct Option is A

To determine the correct answer, we need to understand how soil particles are related to the given options.

Soil texture refers to the relative proportion of different-sized mineral particles in soil, namely sand, silt, and clay. The size and distribution of these particles determine the soil's ability to hold water and air, impacting its overall productivity and use in agriculture. Therefore, the texture of soil is directly determined by the types and sizes of soil particles present in it.

1. Texture: Soil texture is primarily determined by the percentage of sand, silt, and clay particles it contains. This option matches exactly what soil particles determine.
2. Field Capacity: This refers to the amount of soil moisture or water content held in the soil after excess water has drained away and the rate of downward movement has decreased. While particle size affects field capacity, it is not a factor that directly determines the field capacity.
3. Water Holding Capacity: This is affected by soil texture but not solely determined by it, as soil structure also plays a significant role.
4. Soil Flora: This refers to the plant life present in the soil, which is not directly determined by soil particles but rather by a combination of factors including soil texture, nutrients, and environmental conditions.

Thus, the correct answer is texture, as it is the aspect of soil that is directly determined by soil particles.
