TOWARD SOIL CONSERVATION
The wealth of this Nation is rooted in the soil. Thirty million people earn their living directly
from farms and ranches. The remaining 100 million Americans depend upon the soil for most
of their food, much of their clothing, and many other necessities.
Today the soil of this Nation is being wasted away. Erosion is steadily washing good soil
out of the fields and pastures, into the streams, down the rivers, and to the sea.
The pictorial map on the opposite page, based upon a typical farming area of the Southern
States, shows the land in patterns of soil depletion and waste. Destruction of the land is
caused chiefly by square farming-plowing uphill and downhill in straight rows despite the
curving topography-which produces l
O SHEET EROSION, by which the top layer of soil is
skimmed off the land.
O GULLIES, a moe obvious form of erosion, that gouge out
the sides of sloping fields.
Other influences that deplete the soil include
G ONECROP FARMING, without proper rotations, which
weakens the soil and brings on erosion.
O O OVERGRAZING OF PASTURES, which strips the land
of soil-binding grasses, and
, ABUSE OF WOODLANDS, which destroys Nature's
best protective c ver for the soil.
Together, these processes contribute toO
FLOODING of ,ttom lands, by causing an excessive and
rapid run-ofof, water.
The American people have awakened to this stealthy pillage of their land, and on millions
of acres they are now supplanting waste with conservation. The following pages show how
the individual problems of soil depletion are being solved and describe the new patterns of soil
conservation that are being etched upon the land.
