1. Nitrogen Management in Minnesota as Influenced by Soil Drainage and Tillage

Tile-draining, conventional tillage and pre-plant applications of nitrogen (N) fertilizer are prevalent practices among Minnesota corn growers. However, climate change and increasingly warmer and wetter spring conditions have called for a re- evaluation of the appropriateness of these practices for continued sustainable corn production. The objectives of this study are to determine the influence of drainage, tillage and N application timing on (1) corn grain yield and N uptake, (2) corn N demand... G. Paiao, F. Fernandez
