The soil moisture regimes are defined in terms of the groundwater level, and in terms of the seasonal presence or absence of water held at a tension of less than 1500 kPa in the moisture control section. It is assumed in the definitions that the soil supports whatever vegetation it is capable of supporting, i.e., it may be in crops, grass, or native vegetation, but it is not being irrigated, nor fallowed to increase the amount of stored moisture. These cultural practices affect the soil moisture conditions as long as they are continued.
