| To understand multiple dimensions and connections in today’s complex farming systems, it is essential to move beyond the narrow disciplinary focus found in most university agriculture courses and learn from farmers who are intimately integrated with farm decisions. In many ways, the classical agriculture department is a human construct developed for our convenience, and as such it scarcely represents an ecological structure operating on farms. To adequately delve into the mechanisms of crop/weed, crop/animal, product/market, and myriad other interactions involved in agriculture, it is essential that we draw on methods from the biophysical and social sciences to help us understand the human activity system that is farming. For more than a decade, we have... |

| The conventional corn-soybean rotation in the United States (USA) is a leaky system with respect to nitrate-nitrogen (nitrate-N), in part because these crops grow only five months of the year. Ecosystem functioning can be improved with the use of an appropriate fall-planted cover crop, but this practice is not common. Organic soybean production in the USA typically relies on delayed planting, crop rotation, intensive harrowing and interrow cultivation for weed control. Research on timing of shredding of a fall-planted winter rye (Secale cereale L), cover crop in the spring after soybean have been no-till planted into the standing rye has shown this practice can work for organic producers. On-farm and on-station research in Minnesota (MN) has documented... |
