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.
Residual herbicides applied at or before planting are critically important to controlling emerged Palmer amaranth in dry bean. Research at the Panhandle REC assessed the efficacy of PRE and pre-plant incorporated (PPI) residual herbicide programs.
Across Nebraska, the use of cover crops is increasing. Most commonly, winter cover crops are planted during the fallow period between corn or soybean harvest and the next crop. However, other windows for cover cropping exist in Nebraska.
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).
How well do cover crops control weeds and can they offset herbicide costs in corn-soybean cropping systems across the Corn Belt? That's the focus of a multi-state meta-analysis of 15 cover crop research projects.
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 survey and landscape analysis is being conducted to better understand the ecology of both the wheat stem sawfly and its parasitoid, the most effective control method for the wheat stem sawfly in Nebraska.
