Concept:Soil with low water holding capacity (like sandy soil) has large pores, leading to good air exchange and fast water drainage.
Explanation:Water holding capacity is the soil's ability to retain water.
Low water holding capacity soils have big gaps between particles.
These large pores allow air to move freely, giving good aeration.
They also let water drain quickly, meaning a high percolation rate.
For example, sandy soil drains fast and is well‑aerated.
In contrast, clay soils hold water tightly, causing poor aeration and slow percolation.
Check each option:
Option A says poor aeration – false because low‑capacity soils have good aeration.
Option B says low percolation rate – false; they have high percolation.
Option C says both poor aeration and low percolation – false.
Option D correctly states good aeration and high percolation.
Answer:D. Soil with low water holding capacity has good aeration and high percolation rate.
