Effect of Methods of Harvesting Peanuts on Soil Depletion and Growth of Succeeding Crops A large percentage of the peanuts grow^n in the United States is har- vested for market by removing both nuts and vines from the soil. As dis- cussed previously, such a system of management is know^n to remove large quantities of nutrients and to lower the productivity of the soil. In some sections of the Southeast, the practice of harvesting the peanut crop by grazing hogs (hogging-off) is followed. With such a practice most of the nutrients are returned to the soil in the plant residues and animal manures. Peanuts handled in this manner may serve as a soil-building crop. Results of studies conducted at the Wiregrass Experiment Station in Alabama with different cropping systems including hogged and dug pea- nuts are shown in table 12. Peanuts planted continuously on the same soil, unfertilized and harvested by hogs, were found to yield quite satis- factorily ... as well, in fact, as those grown in rotation with fertilized.
