  • Figure 1. Soil macronutrient concentrations under Maximum Farming System (MFSyst) management and Conventional (Conv) management practices. Data displayed as medians with interquartile ranges over three states, 3 sites, and 3 years (N = 96). A: Exchangeable potassium (K), available phosphorus (P), and sulfur (S). B: Magnesium (Mg) and Calcium (Ca). Bars within Mg or Ca having the same letter are not significantly different at p < 0.01
  • Figure 2. Medians and interquartile ranges of soil enzyme activities (A, B) and SOM (C) in 0-15 cm depth under maximum farming system (MFSyst) and conventional (Conv) management in years 2015 (N = 32), 2016 (N = 32), and 2017 (N = 32). Bars within a year having the same letter are not significantly different at p < 0.05
  • Figure 3. Medians and interquartile ranges of corn (A) and soybean (B) yields at maximum farming system (MFSyst) and conventional (Conv) management in years 2015, 2016, and 2017 (Corn yield at MFSyst N = 54, Conv N = 48; Soybean yield at MFSyst N = 42, Conv N = 37). Significant differences between MFSyst and Conv are indicated by different letters
