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

 High Soil pHTile-drained fieldsWarm Soil Temperatures
 High residue cropping systemsAbove 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.

The goal in crop production with nitrogen is to ensure as much of it as possible is available for plant uptake, where it can then be converted to grain throughout the growing season. While we know nitrogen is important to our crops, do we know what role it plays and how to ensure it’s available for optimal crop growth and production?

Record-setting rain during the 2018 fall limited or prevented fertilizer applications in many regions of the U.S. Add to that an abundance of late winter precipitation, below average temperatures and large snow melt have led to record-setting floods in parts of the Midwest and saturated fields in other parts of the U.S., making it difficult for growers to hit the ground running this spring.
