New discoveries
in the domains of plant composition and animal nutrition and the
improved methods of rapid and accurate valuation will accelerate
this tendency. Even now, manufacturers of food products print on
cartons and in advertising matter quality reasons for the superior
food values of certain articles. At least one firm produces two
parallel sets of its manufactured foods, one for the man who does
hard physical labor, and the other for the brain worker. Quality, as
related to the needs of the body, whether of beast or man, is
rapidly becoming the first question in judging any food material.
The present era of high prices makes this matter even more
important.
In view of this condition and tendency, the fact that dry-farm
products are unusually rich in the most valuable nutritive materials
is of tremendous importance to the development of dry-farming. The
small average yields of dry-farm crops do not look so small when it
is known that they command higher prices per pound in competition
with the larger crops of more humid climates. More elaborate
investigations should be undertaken to determine the quality of
crops grown in different dry-farm districts.
