soil water anomaly does not affect the evaporation rate. In the southwest, evaporation sensitivity to soil moisture, particularly deeper soil moisture, which can retain anoma-lies from week to week, is limited by an absence of transpiration caused by sub-wilting moisture levels and minimal vegetation cover.

Soil moisture is one of the main factors influencing soil nutrients. In lower rainfall, the soil moisture reserve should be taken into account when choosing fertilizer rates. Soil moisture above certain levels will generally give a greater economic return to fertilizers.

Treatments comprised two irrigation strategies: (i) maintaining a constant VWC of 0.30, 0.45, or 0.60 m 3 ·m-3 by applying small amounts of tap water over time; and (ii) providing a fluctuating VWC (0.30 F), in which a large amount of tap water was applied when the VWC decreased to below 0.30 m 3 ·m-3.
