Quantifying changes in soil health over time: Soil organic carbon and nitrogen storage due to long-term tillage system, crop rotation, cover crop and nitrogen fertilization

Start & End Dates = September 1, 2018 – August 31, 2022

Primary PIs = Dr. Laura Van Eerd, Dr. David Hooker


Using the long-term experiment at Ridgetown which is applicable to humid-temperate climates, objectives are to:

-Assess the differences in soil health (soil organic carbon and total N) among crop rotations (C-C, C-S, S-W, C-S-W, S-Wrc, C-S-Wrc), tillage systems (zone-tillage vs. conventional fall plow with spring secondary tillage), and N fertility treatments (starter vs. starter + 150 Lb / N/ac)

-Determine the influence of time on SOC and TN accumulation by identifying sequestration rates and the change in storage from 2006 to 2018

-Quantify the role or red clover cover crop and N fertilizer in crop rotation on SOC and TN storage and sequestration rates

-Characterize the relationship of soil health with crop yield and variability in yield among years (i.e., resiliency) associated management practices.
