Understanding the Power of Emergence Flag Tests in Corn and Soybeans
Flag tests offer a simple, effective way to measure emergence timing and uniformity—two major factors in maximizing yield. Using colored flags at regular intervals, growers can track exactly when each plant breaks through the soil. This allows you to identify delays in emergence and pinpoint problem areas within your planter or field.
The guide shown from AgriGold outlines how to flag every 1/1000th of an acre per planter row, then monitor and mark new emergences every 12 hours with different colors. At the end, you can evaluate how many hours it took for full emergence, calculate delayed emergence percentages, and assess the impact at harvest.
In both corn and soybeans, even emergence leads to stronger stands, better nutrient use, and improved yield potential. Don’t guess—flag your emergence and farm with confidence.
