One of the cornerstones of regenerative agriculture is to have plants growing in the soil for as many days of the year as possible. While today’s agronomic practices are predominately based on using annual cash crops, it is an opportunity to get cover cropping into the management fold.
Nutrient runoff from agricultural production is a significant source of water pollution in the U.S., and climate change that produces extreme weather events is likely to exacerbate the problem. A new study from the University of Illinois Urbana-Champaign looks at how extreme rainfall impacts runoff and suggests possible mitigation strategies.
In 2015, the state of Illinois developed a strategy to reduce nutrient runoff that went into the state’s waters — the Illinois Nutrient Loss Reduction Strategy (NLRS). This plan sought to reduce nitrate-nitrogen (N) loads by 15% and phosphorus (P) loads by 25% by 2025.
One of the many benefits of cover crops is they let growers reduce nutrient runoff and help improve water quality in local watersheds. However, in some cases farmers may need to terminate covers and using herbicides is often the go-to method.
One way to control runoff of nitrogen and phosphorus is to have a growing crop on the field. “That’s why cover crops are so important,” said Gary Schnitkey, professor at the University of Illinois and U of I Extension farm management specialist.
When it comes to nutrient loss, no-till practices sometimes get the blame. But a study out of Iowa found that tillage also contributes to nutrient runoff.
