Abstract

Humic products have been used as an amendment for crop yield enhancement for nearly a century. However, very little field research has been conducted with these products on university research farm settings in the U.S. Midwest. One of the issues that has hampered scientific progress of humic products has been their inconsistent crop responses. There are a myriad of possible reasons for crop response variability, some being environmental, some could involve variability in the humic product’s integrity. The objective of this study was to examine corn and soybean growth and production responses to a humic product across enough growing seasons, to generate a database to include a range of growing conditions (i.e., drought, average and wet precipitation amounts).
