From renewable fuels to high-quality feed, corn is one of the world’s most versatile crops. Corn requires adequate amounts of nutrients throughout the growing season with the largest and most critical nutrient deficiencies occurring in growth stages V5 through V8. Deficiencies can be attributed to denitrification, leaching, excessive rainfall, cold spring temperatures, compaction, and dry soil conditions.

Common indicators of corn nutrient deficiencies include visible yellowing of the leaf edges as a result of potassium deficiency and/or a purple hue due to insufficient magnesium.
