This tab contains soil nitrogen leached (NO3) measured into the drains. Water withdrawer and flow meter were installed on drain in each plot. Water samples were taken every 8 hours and flowmeter give a data every 15 minutes. Nitrogen water contents (NO3, NO2 and NH4) and carbon contents (IC, TOC, NPOC, TC) were measured by ECOSYS laboratory (INRA, Grignon, France). The data in the database are derived from daily averages. The water flow meter positions are given in “xy_meas.tab” (meas_type=WF). Flow meters have a measurement sensitivity threshold at 20 l.h-1, when water samples have been taken but the flow is below the sensitivity threshold the rate value has been set at 10l.h-1. Sometimes the system to collect water samples (ISCO) have been down, we suggest estimating an average concentration value with the previous and next values. Sometimes we have few measurements of flow, so we estimate a water flow minimal with “0” as value when there is no measure and a water flow maximal with the mean of existing values.
