Soil Program on Hydro-Physics via International Engagement (SOPHIE)


Soil Program on Hydro-Physics via International Engagement (SOPHIE)

SOPHIE works on the development of an international network that is needed and will be used as a driving force to Harmonize, Standardize and Innovate towards cost-effective measurements of Soil Hydro-Physics (SHP) Properties. It has the ambition to provide a generally accepted degree of harmonization and standardization of SPH property determination in field and laboratory, and to provide SHP data that is based on standardized procedures to be used as a support for the EU Soil Policies.

Soil Hydro-Physics (SHP) properties are THE properties that determine soil-water-interactions:

  1. water flow and water retention, and
  2. with the water flow, the transport of dissolved compounds like nitrogen, phosphates, pesticides, antibiotics, organics, etc. 

As a result, SHP properties play an important role in variety of societal issues: Crop water stress vs. food security, Salinity and Sodicity occurrence, Susceptibility for forest fires, Soil compaction, Dike stability, Greenhouse gas emissions, Soil health, etc.  

The need for reliable SHP properties is widely emphasized by researchers and consultants. However, concurrently it is recognized that harmonization, and the development of new techniques is difficult to accomplish. This is due to the missing attention and missing direct visibility of SHP properties in the societal topics they address. As a result, current methods remain time-consuming. They need to be improved towards cost-effective ones, and should be sufficiently harmonized to be used on EU-scale research.

There are many opportunities to markedly improve the situation, but these require large-scale adaptation, validation and standardization. One example is the adaptation and innovation towards novel remote and proximal sensing techniques. When they are used in combination with modern field and laboratory techniques, they can lead to standardized SHP-properties, directly usable for fast extending current soil databases like LUCAS, and in large scale studies.

The INSPIRATION meeting on Dec 6th 2017 in Brussels was used to build upon commitment among policy-makers, manufacturers, developers, researchers and users. The Motivation and Approach (above) were underlined almost unanimously during the workshop. Representatives of the International Soil Modeling Consortium (ISMC), the International Soil Reference and Information Centre (ISRIC), WEPAL, and the other participants indicated their commitment towards developing SOPHIE, and it was concluded that SOPHIE should be extended. During the EGU meeting (May 2018) we will further elaborate on the implementation of a SOPHIE, its program: the short- and long-term focus and possible partners.

Upcoming events

Gembloux - 30 Jan 2019: Workshop particularly aimed at facilitating benchmarking of conventional soil physical measurements between laboratories.

The specific objectives will be:

  • to enlarge the network of soil physics laboratories involved in SOPHIE
  • to exchange knowledge between these laboratories
  • to identify benchmarking strategies for conventional soil physical measurements.

Vienna, EGU2019 – Tuesday April 9: at TB3:14.00-15.45 hours, Room 2.83. During this meeting we will discuss the general SOPHIE draft research agenda during a public splinter meeting at the EGU2019.
