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.
A University of Kentucky study titled "Productivity benefits of cereal-legume cover crop mixtures under variable soil nitrogen and termination times" suggests that mixing cover crops is a beneficial strategy for modern agriculture.
A benefit of legumes is that they can mine nitrogen, phosphorus, and potash from the subsoil. Frame said a goal of the research is to discover if those nutrients from the cover crop can be used by the cash crop following the cover crop.
With a pivotal spring season ahead, understanding nutrient cycling is critical to developing a successful, resilient no-till system, says Barry Fisher.

Last week we had boots on the ground at the Big Soil Health Event in Cedar Falls, Iowa where agronomist David Kleinschmidt emphasized the importance of considering Carbon to Nitrogen ratios of cover crops and residues.
