To a good farmer, love of his land<br />
is second only to love of his family.<br />
And, improving the land is the best<br />
way to build family security.<br />
The high yields, possible with<br />
modern crops, are a blessing and a<br />
responsibility. High yields make<br />
money; they also rob the soil of<br />
organic matter and plant foods<br />
which must be replaced. You can't<br />
fool crops any of the time.<br />
Fortunately, nature helps us.<br />
Water, sunshine and air provide a<br />
big share of the substance of crops.<br />
We help nature by adding pounds<br />
of fertilizer to the two million tons<br />
of topsoil in each acre of cropland.<br />
The soil needs plenty of nitrogen,<br />
phosphorus and potash, considerable<br />
amounts of sulphur and calcium,<br />
and smaller quantities of magnesium,<br />
iron and other elements. Soil<br />
must also be kept in good tilth to<br />
hold water and air and to supply<br />

plant foods in forms available to<br />
crops. Grass and legume roots supply<br />
much organic matter, as do cornstalks,<br />
straw and cover crops.<br />
Even with clean harvested crops,<br />
tons of crop roots and residues are<br />
usually added to the soil. Balanced<br />
fertilization, with regular plowdown<br />
of crop residues, provides for both<br />
profitable farming and a permanent<br />
agriculture.<br />
Plenty of nitrogen is needed to<br />
break down these raw crop residues<br />
into valuable soil humus. And farm<br />
results show that it is most practical<br />
to turn back some of this organic<br />
matter every year, or in every crop<br />
rotation, to maintain good soil condition<br />
and high yields.<br />
It pays to make it easy for crops<br />
to get all the plant foods they need.<br />
A 100-bushel corn crop needs about<br />
160 pounds of nitrogen for vigorous<br />
growth, plus plenty of phosphorus<br />
for early rooting and sure ripening,<br />
and plenty of potash for sturdy<br />
stalks and heavy ears.<br />
Test your soil and treat it well.<br />
Use enough fertilizer to grow the big<br />
yields you want. Every acre will<br />
produce more food for the nation,<br />
and more income for your family.<br />
For the land's sake and for your<br />
family's sake, fertilize!<br />
Nitrogen Division, Allied Chemical,<br />

fertilizers. ARCADIAN' Nitrogen<br />
is produced in a complete line of<br />
liquid and dry nitrogen products,<br />
for use in manufacturing mixed fer-<br />
tilizers, and for direct application to<br />
the soil.<br />
