is better supplied with potassium than with any other important
element.

I would suggest that you make liberal use of magnesian
limestone,--at least two tons per acre every four or five
years,--and the initial application might better be five or even ten
tons per acre if you are ready to make such an investment.

I am sorry that the nitrogen content of the soil was not determined,
or at least not published in the bulletin. There can be no doubt,
however, that your soil is extremely deficient in organic matter and
nitrogen, and you will understand that liberal use should be made of
legume crops. The known nitrogen content of legumes and other crops
will be a help to you in planning your crop rotation and the
disposition of the crops grown.

As to phosphorus, it is safe to say that in the long run fine-ground
rock phosphate will prove the best investment; but for a few years
it might be best to make some use of acid phosphate in addition to
the raw rock, at least until you are ready to begin turning under
more organic matter with the phosphate.

There is only one other suggestion: If you wish to make a start
toward better crops as soon as possible, you may well use some
kainit,--say six hundred pounds per acre every four or five years,
preferably applied with the phosphate. In the absence of decaying
organic matter, the potassium of the soil becomes available very
slowly. The kainit furnishes both potassium and magnesium in soluble
form and it also contains sulfur and chlorin. As soon as you can
provide plenty of decaying organic matter you will probably
