As the furrow-slice is turned they are broken. Hence the moisture from below is checked in its upward current just below the bottom of the furrow. Hence plants ger- minating near the surface are cut oft from all supply beneath. This is why corn on spring plowed ground starts slowly in the early part of the season. Fall plowing cannot be recommended for all climates and local ities, but should be more generally practiced t

DIAGRAM SHOWING WHAT EFFECT DISCING, HAR- ROWING AND ROLLING HAS UPON THE PLOWED FIELD. Of course the surface is made much finer. But the disc reaches down to greater depths and begins to settle the loose earth upon the furrow-bottom. The packing grad- ually re-establishes the capillary connection. The fact that spring plowing requires some time during the early part of the season to accomplish this process tends u> hold the moisture of the soil until later in the summer when it is most needed. increase the amount of plant food available for the crop the next sum- mer. This is true to some extent even though the crop is not turned.
