Nitrogen Inhibitors for Improved Fertilizer Use Efficiency

January 14, 2019
This article looks at how some nitrogen inhibitors temporarily reduce populations of Nitrosomonas and Nitrobacter bacteria, the soil bacteria responsible for converting ammonium to nitrite and nitrite to nitrate as well as what to look for in product claims.

Spring N application in the field
Growers planning for their 2019 N management in corn might consider the potential for increased N efficiency and reduced loss from split applications at planting and up to R3 growth stage rather than a fall application.

Consequences of Fall-Applied N

November 9, 2018
A fall nitrogen application has a relatively high loss potential and is considered the riskiest N management practice. Consider breaking tradition and splitting your N applications next year to coincide with when your corn most needs more N.
