Next summer may see another
drought in the Great Plains as
severe as the 1980 summer’s, and it
could be even more destructive in
the Com Belt.
The West, too, may be drier than
normal next summer, but the Ohio
River Valley may have a wetter
than usual spring.
The southern Plains should have
good weather in June for har

tunately plants have a wide pH
tolerance range. However, the best
pH range will vary somewhat with
the crop to be grown and soil type.
Most crops do best on well-limed
soils. Alfalfa is very sensitive to
soil acidity and produces best
within a pH range of 6.5 to 7.0.
Other forage legumes such as the
clovers, birdfoot trefoil and the
vetches are somewhat less sen
sitive than alfalfa to soil acidity.
These legumes do well within a pH
range of 6.0 to 7.0.
Small grains are generally
considered to have a wide range of
tolerance to soil acidity. Oats
seems to produce well as a pH as
acid as* 5.5 or on well limed soil.
Wheat does well within a pH range
of 6.0 to 7.0.
Barley, however, is almost as
sensitive to soil acidity as alfalfa
and should be grown on soil limed
to pH 6.5 to 7.0.
Corn also has a wide range of
tolerance to soil acidity. Although,
on many soils, it will produce well
on soils as acid as pH 5.8, it is

severe cold of this winter in the
East.
“Our predictions are based on
physical forces as far as we know
them and the thermodynamic
effects of carbon dioxide and other
particles m the atmosphere which
we link up with statistics, recorded
climate patterns, or how the at
mosphere has responded to these
physical forces in the past,”
Bryson explained “We may
finally be getting a handle on long

Waiting for rain, a Texas farmer looks over his drought
stricken cotton fields. Water shortages plagued the fragile
ecology of the Great Plains for the past few years and con
tinued this winter. Forecasters predict last summer’s severe
drought will be matched again this year.
