As corn enters the critical grain fill stage in August, nitrogen demand is still high. While many growers front-load nitrogen in the spring, research shows that split applications, especially in-season fertigation with melted urea, can significantly improve nitrogen efficiency and yield potential.
Why Corn Still Needs Nitrogen in August
Corn doesn’t stop growing after tassel. In fact, up to 30–40% of total nitrogen uptake occurs after pollination. During the R2–R4 stages (blister to dough), specifically ammoniacal nitrogen is essential for:
- Kernel development
- Stalk strength
- Disease resistance
Applying nitrogen now helps protect yield potential and ensures your crop finishes strong.
What is Melted Urea?
Melted urea is a liquid form of nitrogen (UAN alternative) that's fully dissolved and ready to apply. It’s ideal for:
- Fertigation systems
- Foliar feeding
At Red Cedar Ag, we now offer melted urea in-season, ready to integrate into your nutrient plan. Whether you’re running a pivot or looking to top off your corn with a late-season boost, we’re here to help.
