In the rougher corn sections, fall plowed fieldswash so badly and ditches form so quickly that the practice shouldbe discontinued. This is especially true of soils which have beendepleted of their humus.

Such conditions havecompelled corn growers in these localities to rotate, and in somecases to even sow the fields to grass Fig. 67.
