Document Summary

Intensive tillage used to loosens soil and allow for aeration water drainage and root growth. Reduced om (organic matter) and harms soil quality and structure. Leads to soil erosion off farm and on farm cost. Monocultures uniformity and specialization makes mechanization more cost effective. And increases need for external inputs to control pest and maintain soil fertility. Synthetic fertilizer needed to support monocultures since animal manure and crop rotation not employed. Leaches easily more fertilizer + higher yield the right conditions. Inexpensive famers just use one in case of perfect conditions. 70 percent of water is used for agricultural purposes. In absence of crop rotation need an outside intervention. Health effects target organisms on and off farm. Plant breeding collects seeds with favorable traits repent them.
