Soil moisture across inter-annual precipitation variability treatments at a grassland site in the Jornada Basin, 2011-2013

This completed dataset contains soil moisture data from a study at the
Jornada Experimental Range (JER) in southern New Mexico. The study was
designed to assess the effect of interannual variability in
precipitation on average aboveground net primary productivity (ANPP)
in Chihuahuan Desert grasslands. The study began in 2009 and has five
precipitation treatments (see Methods). While the study began in 2009,
contains 50 plots (10 per treatment) and is ongoing, these data were
only collected from July 2011 to December 2013 in a subset of 20 plots
(4 per treatment). This dataset is intended to provide information
about the amount of water in the top 30 cm of soil as well as verify
that experimental precipitation manipulations are effective.
