This fourth video in the series shares key findings from a 2015–2020 Douglas County study on 4R nitrogen management and cereal rye cover crops, presented by Lowell Gentry.

Using cover crops as a nitrogen catch crop is not a new idea. Lowell Gentry, research agronomist and retired University of Illinois principal research specialist, shares insights from 1884 that hold true today.

What impact does the carbon-to-nitrogen ratio of plant residues have on plant-available nitrogen and tile nitrate losses? Lowell Gentry explains the connection to soil nitrogen mineralization in the second video of our five-part series on reducing nitrate loss in Illinois agriculture.

In this video, Lowell Gentry shares 30 years of nitrate data from the Upper Embarras River and trends in nitrate loss.
