This data package contains volumetric water content measurements from soil hydroprobes on the permanent LTER-1 transects located at Chihuahuan Desert Rangeland Research Center (CDRRC) in the Jornada Basin. The control and treatment transects (2.7 km in length, parallel to each other) extend from the middle of the College Playa to the foot of Mt. Summerford. The Treatment transect was treated annually with ammonium nitrate fertilizer (NH4NO3 at 10g N/m2/yr) until 1987. Probes are located at 30 meter intervals along the control transect (n=89) and at every 5
th
station at the Treatment transect (n=19). Measurements were taken at 5 depths using a neutron probe (CPN Model 503DR Hydroprobe) and at 30 cm depth intervals to a maximum depth of 110 cm. Neutron probe readings taken in 6 lysimeters along transects are also included. This dataset consists of the calculated water content (cm3 water/cm3 soil) data derived from thermalized neutron counts found in EDI packageID knb-lter-jrn.210001001. Measurements were taken at 2 week intervals from April 1982 to 1987, and ongoing measurements are taken monthly since.
