- ... We tested the null hypothesis that nitrification and the distribution of archaeal and bacterial nitrifying communities would not be impacted by long-term applications of the herbicide, glyphosate, to glyphosate-resistant (GR) and non-glyphosate-resistant corn (nonGR) under conventional tillage (CT) and reduced tillage (RT) systems. Bulk and rhizosphere soil nitrification potential rates and quanti ...

- ... Conversion from furrow to sprinkler irrigation is a recommended conservation practice for improved water-use efficiency (and erosion control), but effects on soil quality indicators are unknown. Several soil quality indicators were therefore quantified within a northwestern United States Conservation Effects Assessment Project (CEAP) watershed after changing from long-term furrow to sprinkler irri ...
