Soil Surface Nitrogen from Hess’ Rainfall Intensification Study — Main Cropping System Experiment (MCSE)
Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use
Nitrate and ammonium concentration in surface soils (0-20 cm) collected every two weeks under extreme and control rainout shelters over the study period.
This datatable is part of the Nitrogen Dynamics from Hess' Rainfall Intensification Study dataset.
This dataset contains results from L. Hess’ dissertation research on the effects of rainfall intensification on N leaching, soil inorganic N pools, soil N transformations, and crop N content in the MCSE Conventional (T1) and No-till (T2) treatments. Data supporting Hess et al. (2020).
