1. Tracking Multi-Nutrient Dynamics in Spring Crops Using Field Hyperspectral Imaging and Chemometrics

Within crop nutrient ecology we still lack a clear and growth-stage-specific understanding of which nutrient elements are most limiting in field conditions and during different periods of the growing season, and how the (co-)limitation pattern is influenced by different management conditions. This is particularly relevant in Nordic systems with short growing seasons, where nutrient constraints can appear rapidly. At the same time, precision nutrient management still requires robust non-destructive... E. Lennartsson, J. Oliveira, M. Weih
