Soybean planting progress (or the lack there of) for Indiana and much of the Midwest is one of the slowest on record. Indiana soybeans normally reach 50% planted by May 20th, but we are only at 6% by the same period.

Soybeans in Indiana often show potassium (K) deficiency symptoms during seed fill – leaf margin chlorosis to necrosis.
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.
