Chart of potential for nitrate-N leaching in spring 2017

Risk of Nitrate Leaching Across Nebraska as of May 21, 2017

May 25, 2017
Following heavy spring rains UNL soil scientists model potential loss of nitrate-N to soil leaching, finding an average 14% loss from mid-April levels, with three sites with much higher losses.

Kansas University Research: ‘Weather Whiplash’ Triggered by Changing Climate will Degrade Midwest’s Drinking Water

April 3, 2017
One consequence of global climate change is the likelihood of more extreme seesawing between drought and flood, a phenomenon dubbed “weather whiplash.” In a peer-reviewed study researchers at the University of Kansas discuss how weather whiplash in the American Midwest's agricultural regions may after water quality, forcing municipalities to seek costly remedies to provide safe drinking water to residents.

Finding Win-Wins for Manure: Maximizing Soil Quality Benefits

March 6, 2017
Manure offers crop production wins by providing valuable nutrients and helping build soil organic matter and an active soil microbial community. Soils with organic matter levels on the low end of their typical range can benefit the most from manure applications that do not exceed the crop’s nitrogen requirements. Organic matter also improves soil aggregates which in turn helps increase infiltration of precipitation and irrigation water, improves water-holding capacity of the soil, and reduces runoff and erosion. Soils with these characteristics experience greater drought tolerance.

Cutting Costs Without Hurting Yields? Check Fertilizer N Rates in Corn after Alfalfa

February 22, 2017

With tight crop margins for the 2017 growing season, many farmers are looking for ways to cut input costs without hurting yields. One way to do this is by giving the appropriate nitrogen credit when calculating how much N to apply to corn grown after a prior alfalfa crop.
