Soil and foliar carbon and nitrogen content and stable isotope ratios from rainfall manipulation experiments at the Jornada Basin LTER, 2011-2020

As rainfall extremes are expected to increase in novel magnitude and
frequency, especially in dryland regions, we asked how prolonged and
directional shifts to water availability may affect ecosystem carbon
and nitrogen dynamics. This data set includes foliar and soil carbon
and nitrogen stable isotope and concentration data collected from
multiple long-term rainfall manipulation experiments at the Jornada
Basin LTER. Datasets also include rainfall data adjusted to rainfall
manipulation intensities. Collection dates range from 5 to 14 years
since the onset of experimental treatments. The primary plant
species targeted for this study were the dominant grass, Bouteloua
eriopoda, and the dominant shrub, Prosopis glandulosa.
