Farmers and their advisors face increasing challenges from low crop prices, extreme weather and pressure to improve water quality. A growing marketplace of tools and products promises to help meet these challenges, but has in turn created a new problem: information overload.

This problem is especially acute for precision management of nutrients, one of the fastest growing agricultural sub-sectors.
