A soil has a bulk density of 1.4 g cm⁻³ and a particle density of 2.65 g cm⁻³. Its gravimetric water content is 0.25 g g⁻¹ at field capacity and 0.12 g g⁻¹ at the wilting point. Using the relation θ = w · (ρ_b / ρ_s) to convert gravimetric water content w to volumetric water content θ, calculate the soil's available water capacity (AWC) in millimetres of water per metre depth of soil. Round your answer to the nearest millimetre.
