Objectives
- 1) To determine the impact of fertilizer placement and timing in direct-seeding systems on N fertilizer-use efficiency, herbicide usage, and weed communities. This objective is being met through the establishment of a short-term management study in three agroecological zones of the Black soil zone.
2)To determine the impact of P and K fertilizer on weed-crop competition. This objective was met through a graduate student MSC. thesis project.
