This study will examine the nitrogen fertilizer practices of timing, placement and form, to improve nitrogen use efficiency and economics of potato production. The project will be undertaken in two phases: Phase 1 will evaluate treatments encompassing a range of timing, placement and nitrogen source practices; Phase 2 will take the most effective of the treatments and improve on the combination of timing, placement and form practices.
- Determine optimal timing, placement and source of Nitrogen fertilizers for irrigated potato;
- Determine the impact of Nitrogen mineralization of soil on potato response to fertilizer additions;
- Evaluate the effectiveness of monitoring plant Nitrogen status to adjust fertigation additions.
