Significant experiments in the prac-
lice OF fallowing land have recently
been conducted by the United States
department of agriculture at San
Antonio. Tex These experiments, ac-

gators obtain larger crops of corn or
cotton from biennially cropped land.
On the other hand, biennially cropped
winter oats did show a slight Increase.
This increase, however, is proba-
bly, not sufficient TO Offset certain

widely in different regions. At San
Antonio the following period varied
from sixteen TO nineteen months. Ac.
cording to a widespread belief land
cultivated for this period but bear
ing no crop would retain so much
moisture that any crop raised on 70
the following year would benefit ma
terially. Some persons have gone SO
far as TO assert that the quantity Of
moisture would be practically double
that in land cropped annually. II
this theory could be substantiated its
Importance TO semiarid regions Is OBJ
vious. Unfortunately the results OF
the recent experiments which are con-
tanned in bulletin No. 151 of the
United States department Of agricul'
ture, entitled, Experiments in Crop
Production on Fallow Land at San An
tonic, Tex" do not bear out this
contention.
The experiments dealt with three
crops, corn, cotton and oats, and COW
cred three years, 1911. 1912 and
1913. While no explanation is offered
for this totally unexpected result the
facts speak for themselves. In the
case of winter oats the biennial crop
shows a very appreciable increase.
but 1t is still doubtful whether this
Increase means real profit. Fallow
land is not only unproductive. but its
cultivation actually costs very nearly
as much as does the production of
a crop.
Together with other practical ex-
periments in raising actual crops the
Investigators carried on a series of
measurements designed to determine
the comparative moisture content OF
annually and biennially cropped land.
These measurements showed that
there was only slight difference in
the moisture content Ut planting and
harvesting times, whether the land
had been fa1low for a long or only a
short period Fallowed land shows
a somewhat higher moisture in the
piats at planting time for oats but
otherwise the variations we're neg
ligible. Summing the whole matter
up, the investigators state that the
results of these experiments indicate
that biennial cropping. at least OF
corn, cotton and oats. Is not TO be
recommended for the San Antonio
region.
In considering the application OF
these experiments to other sections Of
the country It must be borne in mind.
however, that climatic conditions at
San Antonio are quite different from
those prevailing in the dry farming
regions farther north The mean an
nuai rainfall at San Antonio is re-
ported as 26.S3 inches. This would
seem to make crop production fairly
certain, but the rainfall is so unequal
ly distributed and long droughts so
common that the beneficial effects OF
this rainfall are much diminished.
On the other hand. the winters are
mild. the thermometer seldom going
below Is degrees, and plant life can
grow practically throughout the year
When supplied with sufficient mois-
ture. the soil produces abundant crops.
