Nutrient leaching fluxes in alley-cropping agroforestry and open cropland (2019-2022)

This data set contains nutrient leaching fluxes of ammonium, nitrate, total nitrogen and dissolved organic carbon and nitrogen, Al, Ca, Fe, K, Mg, Mn, Na, P, and S from three sites of SIGNAL (Sustainable Intensification of Agriculture through Agroforestry) at Dornburg (Thuringia), Wendhausen (Lower Saxony), and Vechta (Lower Saxony) from 2019 to 2022. The lysimeters were inserted into the soil down to 0.6 m depth so that the soil-pore water was collected beyond the crops’ main rooting depth. In each replicate plot of the agroforestry, suction-cup lysimeters were installed within the tree row and at three distances within the crop row: 1 m, 7 m, and 24 m from the tree. In the open cropland, the four lysimeters were placed at the centre of each 10 × 10 m replicate plot. For calculating element leaching fluxes (mg m−2), the measured solute concentrations (mg L–1) in soil-pore water were multiplied by the cumulative drainage fluxes (L m−2), which were estimated using the water sub-model of ExpertN v5.0. This table contains the index of all tables forming this data collection.
