Assessment: WAEC SSCE - Agricultural Science - 2002 (Objective) Subject: Agricultural Science

Question 1 Report

Capillarity is highest in
Answer Details
Capillarity is the ability of water to move upwards through soil against the force of gravity. The rate of capillarity in soil is influenced by the size of the soil particles. Smaller soil particles have greater surface area per unit volume, which increases the forces of attraction between the water and the soil particles, resulting in higher capillarity. Therefore, capillarity is highest in soil with smaller particles, such as clay. Thus, the correct answer is clay.
