As the harvest hustle and fall field work start to slow, it is time to reflect on the growing season to see what worked well and start making decisions for the next season.

Depending on your soil test results; nitrogen, phosphorus, and potassium are nutrients we supply year after year to our corn crop; however, there is a nutrient we might be overlooking when making fertilizer applications. Sulfur is considered the fourth most important nutrient needed by plants. With a reduction in sulfur emissions from industrial and transportation sources, atmospheric sulfur depositions are much lower which has led to an increase in sulfur deficient corn. It is important to adequately supply crops with sulfur to maintain a high yielding crop.
