While most of the site-specific management tools have been for nutrients, we need to realize that farmers need more than fertilizer advice. There is a need to further expand the tools to cover other inputs such as water management. I know that CIMMYT and IRRI has done something in this regard for the Indo-Gangetic Plains, but I am yet to see any such precision tool for Africa or the Middle East where water shortage is a major issue. Is anyone in the forum aware of such technology for these latter regions?
