Similar strong impact of N fertilizer form and terrain position on N2O emission from eroded croplands (Part 1 of data colletcion, table measured_N2O_fluxes)

Soil erosion affects 20% of croplands. However, our understanding of the effect that soil erosion might have on emissions of N2O, which is one of the most potent greenhouse gases, is still limited. This limitation is likely because the small-scale differences in soil properties and fertility induced by erosion (i.e. ranges of erosion states) have barely been considered in studies quantifying N2O emissions from croplands. There are, however, indications that the erosion state itself strongly impacts N2O fluxes, similar to the N fertilizer form. Therefore, our investigations aimed to further explore these indications. The soil and erosion stages of the study area are classified as Albic Luvisols (LVa; non-eroded dry soil), Calcaric Regosol (RGca; extremely eroded dry soil) and Endogleyic Colluvic Regosols (RGco; wet colluvial soil in a depression).

This datasets contains data of soil data, N2O flux obtained from the measurements that were conducted from 03/05/2010 to 03/05/2013 within the hummocky ground moraine landscape of northeastern Germany (CarboZALF-D), modelled N2O flux and Nmin data. The three N fertilizer forms that were used in this study are organic fertilizer with biogas fermentation residue, mineral fertilizer with Calcium Ammonium Nitrate and a mixture of mineral and biogas fermentation residue.
