Soil Particle Size Analysis at Permanent Quadrat locations, Jornada Experimental Range, 2001-2020

This completed dataset, from samples collected in 2001 and 2020,
contains soil particle size analysis (PSA) and sand fractionation data
from soil cores collected at 117 quadrat locations that are part of
the Jornada Experimental Range's long-term Permanent Quadrats study.
The goal of this effort was to help characterize plant-scale factors
related to vegetation dynamics observed in the Permanent Quadrats. At
each quadrat location, 4 cores were collected at 2 depths (0-5cm and
5-20cm) and assessed for percent sand, silt and clay. The sand
fraction, if large enough, was then separated into 5 sand size classes
(53-106 micrometers, 106-250 micrometers, 250-500 micrometers,
500-1000 micrometers, 1000-2000 micrometers) to measure the percent
fraction of each. Long term vegetation data from this study are
available in data packages knb-lter-jrn.210351001 and
knb-lter-jrn.210351002.
