FIGURE 9.9
Sheep-grazed fallow on an Australian wheat farm.
The sheep control moisture-using herbs and serve as a cash crop
during the fallow year. Soil moisture gained during the fallow year combines with rainfall during the following cropping year to
permit a successful wheat harvest. Successive years of wheat production with no fallow are impossible, except when there is unusually
high rainfall. (Photo courtesy of David Dumaresq.)
