Guidelines for mapping differential N from EO at a range of spatial scales

This document has been prepared in the frame of WP3.2, with the aim of addressing nutrient and water differential diagnosis at a range of scales, setting up the procedure to obtain the required EO-­‐based maps of nutrient requirement variability. Among others, the nitrogen (N) is being considered an important agri-­‐ environmental nutrient and this report focuses on provinding maps of N content and uptake in plants as an input for variable rate technology (VRT) tools.
