Commission 1.5 of IUSS - Pedometrics

Pedometrics is the application of mathematical and statistical methods for the study of the distribution and genesis of soils. The Pedometrics commission is part of Division 1 of the International Union of Soil Sciences: Soil in Space and Time. 

Working Groups joining together in 2017 will be:

Digital Soil Mapping

Digital Soil Mapping is the creation and population of a geographically referenced soil database, generated at a given resolution by using field and laboratory observation methods coupled with environmental data through quantitative relationships.

Digital Soil Morphometrics

Digital soil morphometrics is defined as the application of instruments and techniques for measuring and mapping soil profile properties, and deriving continuous depth functions. The soil profile is at the core of digital soil morphometrics. Digital soil morphometrics is not restricted to in situ or in the soil pit measurements, and it combines field observations and measurements with samples taken to the laboratory and also includes measurements on soil cores or soil monoliths. Digital soil morphometrics has the potential to greatly enhance our understanding of soils and how we view them.

Modelling of Soil and Landscape EvolutioN

The IUSS Working Group for Modelling of Soil and Landscape Evolution aims to progress quantitative soil and landscape evolution modelling by bringing together people modelling at (2D- or 3D-) landscape scales and people modelling (1D-) pedons. Landscape modellers need more detailed and mechanistic (soil) process descriptions while pedon-scale modellers need to incorporate matter fluxes (3-D) at the landscape scale in their models.

We perceive that the cooperation of scientists active in landscape- and pedon scale modelling, palaeopedology and pedometrics are needed to bridge this gap. Our main activities aim at enlarging the community of soilscape modellers by model demonstrations and instructive courses and by organizing workshops and thematic sessions in major conferences. 

Soil Monitoring

The Soil Monitoring Working Group was established to encourage best practice in the design, implementation and statistical analysis of soil monitoring networks. Such networks are required to quantify the status and change of soil properties across all spatial scales, to identify where soil functions might be threatened and to assess the effectiveness of initiatives such as the “four per mille” international research program on soil carbon sequestration. 

The working group has organised a series of symposia and special sessions at international conferences, set out the challenges of soil monitoring in a journal article and edited a special issue of the European Journal of Soil Science.

PROXIMAL SOIL SENSING

The IUSS Working Group on Proximal Soil Sensing was formed in July 2008. The Working Group operates under the auspices of both the Pedometrics Commission and the Soil Physics Commission of the International Union of Soil Sciences (IUSS).

Our group’s purpose is to enable greater interaction and collaboration between scientists and engineers with a common interest in applying state-of-the-art sensing technologies to the study of soil processes and spatio-temporal soil variability. We bring together various research groups and practitioners from around the world who are working on the development of proximal soil sensing (PSS) techniques.

The working group links strongly to all subdisciplines in soil science, particularly the links between soil physics, soil chemistry, pedometrics and digital soil mapping. Key linkages to other disciplines include agronomy, electronic engineering, mechatronics, spatial statistics, chemometrics, mathematics, geophysics and remote sensing as well as disciplines within the applied geosciences, archaeology and ecology.
