This pathway advances multiple-benefit landscape agronomy by investigating and demonstrating how 4R-based nutrient management can move beyond yield enhancement to simultaneously regenerate soil health, stabilize carbon stocks, and improve human nutrition through nutrient-dense crops.

Pathway priorities:

1. Quantify environmental co-benefits of agricultural production, such as carbon stabilization, nutrient retention, and water quality protection, to strengthen the evidence base for multiple-benefit agronomy.
2. Optimize 4R nutrient management across topographic, soil, and hydrological gradients to account for spatial and temporal heterogeneity in agricultural landscapes.
3. Demonstrate how specific 4R source, rate, time, and place combinations stabilize soil carbon, increase soil organic matter, and reduce nutrient losses.
4. Link soil biological and chemical processes under 4R management to nutrient density and dietary quality, strengthening the evidence base for nutrition-sensitive agronomy.
5. Generate Minimum Viable Products (MVPs) that demonstrate measurable, scalable, and integrated gains in productivity, soil health, ecosystem services, and nutritional quality and density.
