KBS148:Nitrogen Dynamics from Hess' Rainfall Intensification Study
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).

- KBS019-024 Soybean Biomass and Nitrogen from Hess’ Rainfall Intensification Study
Aboveground soybean biomass one day before the extreme and control rainfall exclusion plots were harvested. Dried biomass was weighed then threshed to separate grain from stover; both fractions were analyzed for C and N.
- KBS021-006 Soil Nitrification and Mineralization from Hess’ Rainfall Intensification Study
The net nitrification and mineralization rates in soils under extreme and control rainout shelters using resin cores buried in situ over the incubation period.
- KBS137-002 Soil Water Nitrate from Hess’ Rainfall Intensification Study
Nitrate concentration of soil water samples collected from lysimeters buried at 1.2m under extreme and control rainout shelters over the study period./p>
- KBS137-003 Soil Surface Nitrogen from Hess’ Rainfall Intensification Study
Nitrate and ammonium concentration in surface soils (0-20 cm) collected every two weeks under extreme and control rainout shelters over the study period.
