  • Soil and Irrigation Water Test Kit, Model SIW-1 | Hach

    2011-2-1 · We evaluated the nitrogen buffering capacities of two narrow riparian strips (5–8 m) along irrigation ditches located in a typical flat agricultural watershed of the alluvial plain of the River Po (Northern Italy). Subsurface water level and nutrient concentrations were monitored along transects of piezometers installed from crop fields to ditches in two different areas.
