Abstract:	This completed dataset, collected in 2001, contains soil particle size analysis (PSA) and sand fractionation data from soil cores collected at 116 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.

Methods and protocols used in the collection of this data package

Description:

At each quadrat location 4 cores were collected at bare (non-vegetated) areas at 2 depths: 0-5cm and 5-20cm, stacked on top of each other. The 0-5cm deep core had a diameter of 6.1cm and the 5-20cm core had a diameter of 4.6cm. Samples were air dried at room temperature, then hand sieved to 2mm to remove large organic material and the >2mm fraction. Particle size analysis by the hydrometer method was performed on a ~60g subsample. Sand left over from the hydrometer analysis (>53µm fraction) was washed through a 53µm sieve, dried at 105C for 24h to remove moisture, then separated into 5 sand size classes (53-106 micrometers, 106-250 micrometers, 250-500 micrometers, 500-1000 micrometers, 1000-2000 micrometers) in an ultrasonic sifter for 5 minutes and weighed.
