A soil contains 5% moisture from 0 to -20 cm and 15% moisture from -20 to -40 cm. The soil moisture characteristic curve shows that the soil contains 20% moisture at pF = 2 (from 0 to -40 cm). How much water in cm should minimally be added to the soil to establish field capacity ( pF = 2) for both soil layers? a) 2.
