Subtopic: Soil-Water-Plant Relationship
Question Statement:
A soil has Field Capacity $FC = 28\%$, Permanent Wilting Point $PWP = 14\%$, dry bulk density $\rho_b = 1.5\text{ g/cm}^3$, and water density $\rho_w = 1.0\text{ g/cm}^3$. The root zone depth is $D = 80\text{ cm}$. The total available water holding capacity in cm is (rounded off to one decimal place):
