Soils
Heart-of-Egypt is a small station on the double track of the
Chicago-New Orleans line of the Illinois Central, and there are
three other railroads passing through our County Seat. Poorland Farm
is less than two miles from Heart-of-Egypt and only five miles from
the County Seat, with level roads to both.
As to the soil, I may say that in some respects it is poorer than
yours, but in others not so poor. The amount of plant food contained
in six and two-thirds inches of the surface soil of an acre,
representing two million pounds of soil, are as follows:
2,880 pounds of nitrogen
840 pounds of phosphorus
24,940 pounds of potassium
6,740 pounds of magnesium
14,660 pounds of calcium
By referring to the invoice of your most common land, you will see
that Westover is richer in phosphorus, in magnesium, and in calcium,
than Poorland Farm. But, while your soil contains a half more of
that rare element phosphorus, ours contains a half more of the
abundant element potassium. In the supply of nitrogen we have a
distinct advantage, because our soil contains nearly three times as
much as your most common cultivated land, and even twice as much as
your level upland soil, which you consider too poor for farming, but
in which phosphorus and not nitrogen must be the first limiting
element, the same as with ours.
The fact is that the nitrogen problem in the East was one of the
reasons why we have chosen to locate in Southern Illinois. I am
confident that the level lands I saw about Blairville and over in
Maryland are more deficient in organic matter and nitrogen than your
uncultivated level upland, and probably even more deficient than
your common gently sloping cultivated lands, because of your long
rotation with much opportunity for nitrogen fixation by such legumes
will grow in your meadows and pastures, including the red clover
which you regularly sow, the white clover, which is very persistent,
and the Japan clover, which it seems to me has really benefited you
more than the others.
