The Diverse Rotations Improve Valuable Ecosystem Services (D.R.I.V.E.S.) Project networks long-term experiments that have crop rotation treatments across North America. Long-term data across a broad range of growing conditions is critical to assessing the role of crop diversity under erratic conditions (droughts) or on slow-moving variables (soil characteristics). Using multiple metrics, like productivity, economic performance, or nutrient composition, can reveal the benefits and tradeoffs of more diverse cropping systems
