There are several on-going LTAR research currently operational under the PR-NPA LTAR. Some of these on-going research projects include:
- Long-term manuring and continous corn (Established 1912)
- Dryland tillage plots (Established 1970)
- Tillage and crop rotation (Established 1976 and 1979)
- Soil nutrients and tillage (Established 1983)
- Biofuel feedstock studies (Established 2001)
- Sandhills ecology and vegetation dynamics (Survey sites established 1926; 1997 2001 and 2010)
- Grasslands fire, grazing and mowing (Established 1981).
- Continuous corn under irrigation management - ARDC, Mead, NE (Established 2001).
- Corn-soybean rotation under irrigation management - ARDC, Mead, NE (Established 2001).
- Corn-soybean rotation under rainfed management - ARDC, Mead, NE (Established 2001)
