Nitrogen mineralization potential in soils collected from the Jornada Basin LTER-I transect and extracted at field collection time, 1989

This data package contains nitrogen mineralization data from soils
collected along the Jornada Basin LTER (LTER-I) transects in
southern New Mexico, USA. These transects are located in a livestock
exclosure established in 1982 in the Chihuahuan Desert Rangeland
Research Center (CDRRC) and run from the middle of the College Playa
up to the foot of Mt. Summerford (2.7 km in length). Prior to the
exclosure, the study site was moderately to heavily grazed for the
past 100 years. The Treatment transect was treated annually with
ammonium nitrate fertilizer (NH4NO3 at 10g N/m2/yr) until 1987.
Along each transect, 91 stations, each with a plant intercept line,
are spaced at 30 meter intervals. For this dataset, 60 soil samples
(total) were collected along the control and fertilized treatment
transects and mixed with potassium chloride solution (KCl) on Nov
27, 1989, then filter extracted the following day. The dataset
contains a soil moisture correction factor, sample weights, total
inorganic nitrogen (NO3+NO2-N), and nitrogen in ammonium (NH4-N) for
Week F (field) of nitrogen mineralization potentials. The soil
mineralization data complements the biomass harvest measurements
that occurred in September 1989 (dataset knb-lter-jrn.210015001).
This study is complete.
