the dryland areas of the United
States failed when they tried farming
methods used in more humid areas.
A stable agriculture developed only
after summer fallowing was introduced.
Even with modern tillage methods,
no more than 30 percent of all precipitation
is stored in most dryland soils
during an entire fallow period{--}from
fall, at harvest, through the summer
fallow year, to the spring of the crop
year. Evaporation accounts for most
of the precipitation lost. Methods to
suppress evaporation are thus needed.},
