Denitrification in the deep vadose zone: implications for nitrate leaching under agricultural managed aquifer recharge
Published 2025-08-01Get full textManaged aquifer recharge on agricultural lands (AgMAR) is an inexpensive and extensive form of recharge compared to dedicated recharge basins and injections wells. However, uncertain nitrogen cycling outcomes concerning nitrate (NO3–) transport and fate in the unsaturated zone remain. A combination...

Soil macroaggregates and organic-matter content regulate microbial communities and enzymatic activity in a Chinese Mollisol
Published 2019-11-01Get full textThe formation and turnover of macroaggregates are critical processes influencing the dynamics and stabilization of soil organic carbon (SOC). Soil aggregate size distribution is directly related to the makeup and activity of microbial communities. We incubated soils managed for >30 years as resto...
