Integration of flue gas desulfurized gypsum (FGD-gypsum) with cover crops is expected to improve soil quality (SQ). Our objectives were to evaluate the impact of FGD-gypsum and rye on SQ and the contribution of core indicators to account for SQ variability in a rainfed corn-soybean system. A complet...
