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... L. Cihacek, R. Alghamdi Download paper
2. Soil Phosphorus Forms and Cycling Are Altered by Acidification from Nitrogen Fertilization in Long-term Wheat Plots in Swift Current, Saskatchewan Soil acidification from high rates of nitrogen (N) fertilization is recognized as a significant problem in many countries, altering many aspects of soil health. However, new research suggests that this is also a problem for soils receiving lower rates of ammonium-N (NH4-N) over long time periods, including on the North American Great Plains. Soil phosphorus (P) cycling is particularly vulnerable to acidification, because P is optimally soluble in soils within a limited pH range. This... B. Cade-menun, L. Bainard Download paper
