Currently, our nutrient management program involves:
- Development of efficient and environmentally sound fertilization programs for wine grapes (John Havlin), field crops (Carl Crozier and Deanna Osmond), and biofuels (Carl Crozier and Jot Smyth).
- Determination of nitrogen availability coefficients from organic sources (David Crouse, Carl Crozier, and Jot Smyth).
- Understanding of the chemistry and management of organic cropping systems (Carl Crozier).
- Development and maintenance of nutrient decision support systems that both function at the watershed-scale and are applicable to field-scale soil fertility issues (David Crouse and Deanna Osmond).
- Site-specific soil fertility and productivity management, with an emphasis on remote sensing and related geospatial technologies (Carl Crozier, David Crouse, and, Jeff White). More detailed information about these programs can be found in the Geographic Information Sciences Program.
- Tillage effects on nutrients, water storage, and physical properties (Josh Heitman, and Alan Franzluebbers ).
- Soil acidity management (Jot Smyth).
- Training certified nutrient management planners (David Crouse and Deanna Osmond)
- Testing of soil biological activity to predict nitrogen mineralization (Alan Franzluebbers)
In addition to the programs listed above, our nutrient management team are core members of the NC Interagency Nutrient Management Committee, responsible for the implementation of Nutrient Management Planning in North Carolina.
