Dry-Farming : A System of Agriculture for Countries under a Low Rainfall
Widtsoe, John Andreas
Dry farming
alfalfa field should receive as careful soil treatment as the wheat
field. Heavy, thorough disking in spring or fall, or both, is
advisable, for it leaves the topsoil in a condition to prevent
evaporation and admit air. In Asiatic and North African countries,
lucern is frequently cultivated between rows throughout the hot
season. This has been tried by Brand in this country and with very
good results. Since the crop should always be sown with a drill, it
is comparatively easy to regulate the distance between the rows so
that cultivating implements may be used. If thin seeding and
thorough soil stirring are practiced, lucern usually grows well, and
with such treatment should become one of the great dry-farm crops.
The yield of hay is not large, but sufficient to leave a comfortable
margin of profit. Many farmers find it more profitable to grow
dry-farm lucern for seed. In good years from fifty to one hundred
and fifty dollars may be taken from an acre of lucern seed. However,
at the present, the principles of lucern seed production are not
well established, and the seed crop is uncertain.
Alfalfa is a leguminous crop and gathers nitrogen from the air. It
is therefore a good fertilizer. The question of soil fertility will
become more important with the passing of the years, and the value
of lucern as a land improver will then be more evident than it is
to-day.
Other leguminous crops
The group of leguminous or pod-bearing crops is of great importance;
first, because it is rich in nitrogenous substances which are
valuable animal foods, and, secondly, because it has the power of
gathering nitrogen from the air, which can be used for maintaining
the fertility of the soil. Dry-farming will not be a wholly safe
practice of agriculture until suitable leguminous crops are found
and made part of the crop system. It is notable that over the whole
of the dry-farm territory of this and other countries wild
leguminous plants flourish. That is, nitrogen-gathering plants are
at work on the deserts. The farmer upsets this natural order of
things by cropping the land with wheat and wheat only, so long as
the land will produce profitably. The leguminous plants native to
dry-farm areas have not as yet been subjected to extensive economic
study, and in truth very little is known concerning leguminous
plants adapted to dry-farming.
In California, Colorado, and other dry-farm states the field pea has
been grown with great profit. Indeed it has been found much more
profitable than wheat production. The field bean, likewise, has been
grown successfully under dry-farm conditions, under a great variety
of climates. In Mexico and other southern climates, the native
population produce large quantities of beans upon their dry lands.
