Light sandy soils should not be subjected to bare fallow unless they
are very foul with weeds. They should always be covered with a crop to
prevent loss of plant food by leaching.




CHAPTER XII

HARROWING AND ROLLING


HARROWING

After spading or plowing the next operation in the preparation of the
soil is generally raking, harrowing or dragging. The objects of these
operations are:

To break lumps and clods left by the plow and spade and to further
pulverize the soil.

Harrowing and raking aid in controlling soil ventilation, and put the
soil in better condition to absorb moisture.

They check the loss of moisture by making a mulch of fine loose earth
on the surface.

The harrow and rake destroy the weeds.
