See attached file for NC1195's annual report.
Accomplishments
- Better management of N and cover crops (discussed in extension by several members)
- Marshall McDaniel is working on the “old” 1995-1998 NC218 dataset. Goal is to talk with group about 1st draft of publication in March 2019.
- Xiaofei Li now also has NC218 data and will look into economics of the 56 site-year data.
Impacts
- Many researchers had extension activities, publications and presentations that meet our following objectives. Objective 1) Gain a more thorough understanding of the influence of macro- and micro-scale ecosystems and landscape properties on soil N dynamics. Objective 2) Explore optimization of nitrogen management practices through interrogation of corn nitrogen use efficiency datasets from studies conducted across the North Central region. Objective 3) Develop nitrogen management decision-making tools for crop advisers and growers. See Accomplishments and Publications.
