Note: Physical properties of undisturbed sandy loam soil = clay 5.45%, silt 32.05%, and sand 62.50%; bulk density ; porosity 0.49; transmission pores (effective diameter 30 μm–1 mm) occupying 14.1% of the total pore space; and storage pores (effective diameter 200 nm–30 μm) occupying 19.2% of the total pore space. The amount of macro pores (effective diameter 1–10 mm) is tiny and is not taken into consideration.
