Help Growers Adjust Their Nitrogen Needs this Spring

With persistent wet weather patterns across the U.S. causing logistical strain and delay of many growers getting into their fields, some are already making the switch from anhydrous ammonia to other nitrogen sources. This means now is the time to discuss nitrogen source alternatives and nitrogen protection options with your growers.

To find the best solution for nitrogen protection it’s crucial to understand the risk factors for volatilization, leaching and denitrification losses. The table below can identify what losses they may face based on a series of factors.

Risk Factors For Volatilization¹	Risk Factors For Leaching²	Risk Factors For Denitrification³
Surface-applied or shallow incorporated urea or UAN	Pre-plant, at-planting or early post applications	Pre-plant, at-planting, or early post applications
Warm Air Temperatures	All nitrogen application methods	All nitrogen application methods
Moist soil or precipitation event < 0.5”	Loosely textured soils with high infiltration	Tightly textured soils with poor internal drainage
High Soil pH	Tile-drained fields	Warm Soil Temperatures
High residue cropping systems	Above average rainfall and large precipitation events	Saturated soils > 60% water-filled pore space

At Koch Agronomic Services (KAS), we’re proud to be a part of the solution. Whether the nitrogen source is urea, UAN, or anhydrous ammonia, we have a scientifically proven solution to meet the unique needs of your growers. The table below can help you find the right KAS solution dependent on the nitrogen source and loss situation.
