Summary of findings | Comparison of CEAP I and CEAP II survey data and modeling
2022
This report sumarizes the findings of the modeling comparison of the CEAP I and CEAP II surveys that looked at the adoption of conservation practices. The agricultural landscape is dynamic, shaped by public policy, technology, and natural resource drivers among others, which together affect farmer decisions and conservation trends. Comparison of the CEAP I and CEAP II surveys demonstrated that farmers’ adoption of conservation practices resulted in more cultivated cropland meeting loss thresholds for erosion, sediment, surface nitrogen and sediment-transported phosphorus. While use of advanced nutrient technologies increased, by CEAP II more cultivated cropland exceeded loss thresholds for subsurface nitrogen and soluble phosphorus, reflecting the growth in high-nutrient-demand crop varieties, the increase in conservation tillage systems, and the decline in nutrient incorporation. Nevertheless, most cultivated cropland in the United States is under moderate and high levels of conservation treatment, and opportunities exist to improve conservation performance using currently available tools.
