NREC-funded Research in Peer-Reviewed Journal
Thanks to the ongoing work of NREC funded researchers at the University of Illinois and cooperators from the Illinois Fertilizer & Chemical Association, the results of “Soil and crop response to phosphorus and potassium management under conservation tillage” have been published in the Agronomy Journal.
Core Ideas from the published research are:
- No-till reduced yield relative to strip-till
- Deep banding P and K with strip-till resulted in no yield advantage over broadcast applications
- Although there is no agronomic advantage, deep banding effectively reduced soil P and K levels in soil surface layers
- Critical soil test K levels were greater than current recommendations
