John E. Ikerd's book Crisis and Opportunity Sustainability in American Agriculture
"Many "low-input" farmers are already achieving yields equal to or greater than conventional high-yield with low input systems of farming. The knowledge and expertise required to achieve high yields with low inputs are not nearly as common among farmers as are commercial agriculture technologies. However, many others are capable of acquiring this ability, if they realized it was possible and had an incentive to do so. In addition, sustainable agriculture today is in its infancy; sustainable farmers are but the early explorers on a new frontier. As they accumulate increased understanding and know-how, their productive abilities will undoubtedly increase as well. If we invest a fraction of the research and development efforts on regenerative farming methods in the future that we have invested in industrial methods in the past, our overall ability to produce by sustainable methods in the future may easily surpass our ability to produce by conventional methods." p17
