Highlighter green soybeans (N-deficient) are related to the root system, number of nodules, and nodule activity (i.e., evidence of N fixation).

Seeps most often occur where a permeable soil layer is found above a restrictive or less permeable layer.
Unfortunately, many soybeans across the state have been coming up short on N over the past several weeks.
Over the last few years, we have been documenting some remarkable soybean yield responses (upwards of 13 bushels) to sulfur (S) in northwestern Indiana.
