March 3 Webinar: Conservation Learning Lab: Implementation of Cover Crops at Small Watershed Scale

February 24, 2021

AMES, Iowa—The impact of cover crop implementation on water quality in two small watersheds is the topic of the Iowa Learning Farms webinar on Wednesday, March 3.  


During this webinar, Matt Helmers, director, Iowa Nutrient Research Center, will highlight three years of water quality monitoring data after cover crop implementation. The Conservation Learning Lab project, started in 2016, posed the question, “Can high levels of cover crop implementation and reduced tillage be obtained on a small watershed scale, and water quality improvement documented accordingly?” The project focused on small watersheds—between 500 and 1,300 total acres in size—and two pilot watersheds were chosen in Floyd county and Story county.  


The watersheds were chosen for their size and existing Conservation Reserve Enhancement Program (CREP) wetlands that provided baseline water quality monitoring data. The continued monitoring allows for the comparison of water quality before and after conservation practice implementation and to a similarly sized control watershed that did not implement conservation practices. 


“Water quality monitoring at the watershed scale is critical for documenting nutrient reduction from practice implementation,” said Helmers. “Seeing water quality improvement may take years.”  


Helmers’ research focuses on agricultural water quality, including the impact of nutrient management, cropping practices, drainage design and management, and strategic placement of buffer systems on nutrient export in agricultural landscapes.
