Book Description

Excerpt from Crop Rotation Experiments in the Ohio Valley (1925-1936) For centuries men have recommended the practice of alter nating crops systematically. Early agriculturists noted that the practice led to increased yields. Such increases have been found to be due in part to better control Of weeds, insects, and diseases and to better utilization of plant nutrients. It is known, too, that certain rotations will aid in maintaining the supply Of organic matter and nitrogen in the soil and will lessen erosion. However, not all systems of crop rotation are equally desirable. Some rotations may actually bring about soil depletion almost as rapidly as continuous cropping with the same crop, whereas other systems may maintain satisfactory yields with minimum applications Of fertilizer.
