Soil fertility and crop yield response

March 03, 2021

How can we know which soil nutrients are most important for crop production in a region, and how much gain can be had from better fertilization? In a recent collaboration with CIMMYT, we explored how large, new soil datasets collected on the ground can be combined with satellite-based measured yields to answer these questions.
