Research by two USDA scientists finds that humic products can bring modest yield gains, especially during crop stress or in poorer soil types.
Nearly everyone likes a good mystery. And to Dan Olk and Dana Dinnes, solving the questions surrounding the viability of humic products in production agriculture has meant a lot of root digging, leaf measuring, crop scanning and number crunching.
