BOREAS TE-01 SSA Soil Lab Data
Summary
This data set was collected by TE-01 to provide a set of soil properties for
BOREAS investigators in the SSA. The soil samples were collected at sets of
soil pits. Each set of soil pits was in the vicinity of one of the five flux
towers in the BOREAS SSA. The collected soil samples were sent to a lab, where
the major soil properties were determined. These properties include, but are
not limited to, soil horizon; dry soil color; pH; bulk density; total, organic,
and inorganic carbon; electric conductivity; cation exchange capacity;
exchangeable sodium, potassium, calcium, magnesium, and hydrogen; water content
at 0.01, 0.033, and 1.5 MPascals; nitrogen; phosphorus; particle size
distribution; texture; pH of the mineral soil and of the organic soil;
extractable acid; and sulfur. The data are stored in tabular ASCII text files.

1. Data Set Overview
1.1 Data Set Identification
BOREAS TE-01 SSA Soil Lab Data
1.2 Data Set Introduction
This data set was collected by TE-01 to provide a set of soil properties for
BOReal Ecosystem-Atmosphere Study (BOREAS) investigators in the Southern Study
Area (SSA). The soil samples were collected at sets of soil pits. Each set of
soil pits was in the vicinity of one of the five flux towers in the SSA. These
soil samples were sent to a lab, where the major soil properties were
determined. These properties include, but are not limited to, soil horizon; dry
soil color; pH; bulk density; total, organic, and inorganic carbon; electric
conductivity; cation exchange capacity; exchangeable sodium, potassium, calcium,
magnesium, and hydrogen; water content at 0.01, 0.033, and 1.5 MegaPascals;
nitrogen; phosphorus; particle size distribution; texture; pH of the mineral
soil and of the organic soil; extractable acid; and sulfur. These data are
stored in American Standard Code for Information Interchange (ASCII) text files.
1.3 Objective/Purpose
The objective of this study was to develop a complete characterization of all
soil types at the BOReal Ecosystem-Atmosphere Study (BOREAS) Southern Study area
(SSA) sites.
This data set was collected by the Terrestrial Ecology (TE)-01 team to provide a
set of soil properties for BOREAS investigators in the SSA. The soil samples
were collected at sets of soil pits. Each set of soil pits was in the vicinity
of one of the five towers in the SSA. These soil samples were sent to a lab,
where the major soil properties were determined.
1.4 Summary of Parameters
The soil survey samples were examined for the visual characteristics: horizon
designation, color, structure, and depth. The pH, bulk density, total carbon
(TC), organic carbon (OC), and inorganic carbon (IC) values were measured on the
general soil survey samples. Detailed analyses were performed on pit soil
samples representing the soil types at each tower, which included the
measurements listed above and: TC, IC, electric conductivity (EC), cation
exchange capacity (CEC), exchangeable Na+, K+, Ca2+, Mg2+ and H+; soil moisture
retentions (0.01, 0.033, and 1.5 MPascals); total N; total P; particle size
fractions (coarse, medium, fine, and very fine sand, silt, and clay); and
texture.
1.5 Discussion
A general survey of soils was performed at each SSA site in a 1-km2 area with
the tower in the center. Soils were sampled with a frequency that allowed the
production of a 1:5000 map. The soil maps represent a different data set.
A more thorough examination of the soil was performed on a series of soil pits
(four or five) dug on a transect that covered the dominant soil types in each
SSA site. In the summer of 1993, the Old Aspen (OA), Old Jack Pine (OJP), Young
Jack Pine (YJP), and Fen sites were surveyed. The Old Black Spruce (OBS) site
was surveyed in the summer of 1994. The soil survey was performed by an
experienced soil surveyor, using all methods for measuring soil characteristics
that are routinely used in soil surveys. The survey provides a data base that
forms the basic measurements that are necessary for a complete ecological study
of the boreal forests.
The Northern Study Area (NSA) soil survey field work was performed by the BOREAS
TE-20 team, but the analysis of the soil samples were performed by the same lab
and methods as these SSA soil samples.

3. Theory of Measurements
A number of different soil properties were measured for use by BOREAS
investigators. The theory and methods used to measure these properties are as
follows:
Bulk Density: An intact known volume of soil is removed, dried, and weighed; the
density can then be calculated.
TC: All types of carbon will be combusted into carbon dioxide (CO2) in a flow of
oxygen (O2) at 2,500 8F.
IC: IC reacts with acid producing CO2, which is quantified through titration.
OC: Equals measured TC minus measured IC.
EC: The ability of the soil to carry an electrical current, which is indicative
of salt content.
CEC: If a soil is washed with one cation (Ba), and the other cations are
leached, the first cation fills the exchange sites of the leached cation, and
equals the soil's CEC.
Exchangeable Cations: Equals the quantity of cations in the leachate after they
have been exchanged off the soil.
Soil Moisture Retentions: Equals the amount of water in soils under a suction
equal to 0.01, 0.033, and 1.5 MPascals (i.e., field moisture 10th, saturated
moisture, and wilting moisture, respectively).
Soil Size Fractions: Clay and silt are measured based on the principle that the
speed at which a particle will fall in water will depend on the size of the
particle.
4. Equipment
4.1 Sensor/Instrument Description
Bulk density: 10 cm diameter tube, 10 cm long.
TC: LECO CR12 Carbon Determinator 781-600

5. Data Acquisition Methods
Bulk Density: Cylinders of known volume and weight are pressed into the soil
and filled with soil in its natural state. The soil and cylinder are dried at
105 8C and weighed. The soil weight is then calculated and divided by the
cylinder volume (Manual on Soil Sampling and Methods of Analysis).
TC: Measured by combustion of dried soil samples in a LECO CR12 Carbon
Determinator (LECO Corporation Application Bulletin form no. 203-601-071).
IC: Measured through digestion in acid, and evolved CO2 is measured directly as
carbonic acid in a two-endpoint titration (Tiessen et al., 1983).
OC: Equals measured TC minus measured IC.
Total Nitrogen and Phosphorus: Digestion in H2SO4 and H2O2 (Thomas et al., 1967).
Products NH4+ and P were measured colormetrically by the ammonia-salicylate
method (Technicon, 1973) and acid-molybdate blue method (Murphy and Riley,
1962), respectively.
Electrical conductivity and pH: Standard laboratory meter.
CEC: The cations on the exchange are replaced with barium (Ba), which is then
exchanged off the soil with NH4 and the amount of Ba is measured (p. 54, Manual
on Soil Sampling and Methods of Analysis).
Exchangeable Cations: Measured in leachate after Ba has exchanged them off the
soil; Na+, K+, Ca2+, Mg2+ by atomic absorption and H+ by back titration with HCl to
pH 5.1 (p. 83, Manual on Soil Sampling and Methods of Analysis).
Soil Moisture Retentions: Pressure plate extraction (p. 45, Manual on Soil
Sampling and Methods of Analysis).
Soil Size Fractions: Pipette method (p. 6, Manual on Soil Sampling and Methods
of Analysis).
