A soil sample from a cultivated field was analysed for its gravimetric moisture content at field capacity and at the wilting point.

Question Parts

( a )
Calculate the gravimetric water content (as a percentage) for the soil at field capacity and at the wilting point. Use the data below: - Fresh weight at field capacity = 560 g, oven‑dry weight = 500 g. - Fresh weight at wilting point = 540 g, oven‑dry weight = 500 g.
( b )
The bulk density of the soil is 1.3 g cm⁻³. Determine:
( ) Volumetric water content at field capacity (m³ m⁻³).
( ) Available water capacity in mm per metre depth of soil.
( c )
Briefly explain how the calculated available water capacity influences crop water management decisions on the farm.
