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.
Results of research conducted since 2000 to address fertilizer phosphorus (P) for corn will be reviewed. The current fertilizer P recommendations for corn will be discussed and revised recommendations presented at the 2019 Crop Production Clinics.
A UNL study of sensor-based and model-informed fertigation treatments confirms that sensor fertigation treatments are consistently the most profitable and efficient methods of applying N compared to current best management practices (BMPs).
This Q&A addresses questions about baling soybean residue, including its nutrient value and comparison with other sources, economic value, and what should be considered when deciding whether to bale soybean residue.
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.
An article from the Proceedings of the 2018 Nebraska Extension Crop Production Clinics about recent research to validate or adapt canopy sensor-guided in-season N application practices for fields with manure or other organic material applied and to improve the predictionof fertilizer N substitution for organic materials.
