1. N Mineralization Dynamics in No-till Crop Residues in the Northern Plains

Although many studies have been conducted on no-till cropping systems, little is yet known about the dynamics of N mineralization from accumulated crop residues as it relates to providing N to subsequent crops. We conducted incubation studies using individual crop residues placed on the surface of soil columns in leaching tubes and incubating the tubes for approximately 12 weeks (simulated growing season) with periodic leaching.  This was repeated 5 times with a freezing period (winter...
