Question

Various characteristics of soil such as composition, grain size and aggregation determine the

• A. water holding capacity of soil
• B. percolation
• C. temperature
• D. both a and b

Answer 1

The correct option is D both a and b

Various characteristics of the soil such as soil composition (amount of minerals, organic matter, air, water in the soil), grain size (size of soil particles) and aggregation (binding of soil particles to each other) determine the percolation (movement of fluid through soil) and water holding capacity of the soils. The space between soil aggregates provide pore space for retention and exchange of air and water.
