SOIL SESSION. 127- of getting more plant food out of the soil, and so running out the faster the supply of the limiting plant-food element. Where we have fol- lowed the three-year rotation and have added lime to give us better clover, corn has yielded seventy-eight bushels; the soil is not sour to any marked degree. On the next plot to which steamed bone meal has been, applied, the yield gave but two bushels more. Both of these applica- tions have cost annually seven bushels of 35 cent corn. In the case of the phosphorus plot, we have paid for the treatment, and have four bushels of corn clear profit. The important thing here, however, is not this profit for this year or for next year, but it is that the two-hundred:: pounds of steamed bone meal applied carried phosphorus enough to • grow ICO bushels of corn, and we have taken off but Plate 2.—Clover after Oats with Lime Treatment. Under this system, not only is the supply of the limiting element phosphorus being increased, thereby building up the soil, but at the same time an actual profit is being returned. The fact is, there is nearly al- ways profit in a system of soil management whereby the productive ca- pacity is gradually and permanently increased. On the other hand, there is ultimate loss in a system which destroys the productive power of a soil, a system on account of which the yield gradually becomes smaller. On this same soil, on June 7, 1905, five plots, without phosphorus, yielded on the average one and one-quarter tons of field-cured clover hay, while five plots, to which phosphorus had been applied, averaged Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Missouri.
