Project description:


Soil is defined as the top layer of the earth’s crust. It is formed by mineral particles, organic matter, water, air and living organisms. It is a complex, variable and living medium. As well as providing a habitat for many species it performs many vital ecosystem functions including production of food and biomass, filtration of water and transformation of substances such as carbon and nitrogen.

However, the quality of soils is threatened by processes of erosion, loss of organic matter, compaction, salinisation, landslides, contamination and sealing. This soil degradation is accelerating in the EU in the face of global warming, inappropriate land use, pollution and inadequate river management, causing negative effects on human health, natural ecosystems and climate change, as well as on our economy. Furthermore, soil can be considered a somewhat non-renewable resource since it takes hundreds of years to produce a few centimetres of soil.

Many policy areas are relevant to preserving good quality soils, including water, chemicals, industrial pollution, nature protection and agriculture. However, to encourage even greater and more specific work on soils, the European Commission launched a Soil Thematic Strategy in 2006. This seeks to promote and encourage four branches of work around preserving soil quality: awareness-raising, research, integration and legislation.


The MEDAPHON project aimed to build and test a new soil environmental monitoring tool. The project sought to deliver a tool which could measure parameters of the soil biota to assess soil biological and microbiological activity, soil ecological degradation and soil biodiversity from field to landscape level. It hoped to enable scientists to prepare very detailed and large-scale mapping of soil quality in a very efficient way.

Through the tool, the project sought to provide monitoring and spatial delineation of soil biological degradation and contamination, ecological control of agricultural practice, detection of soil biodiversity hot spots. By providing scientists with good quality, up-to-date data, the project hoped to enable soil experts to know when, where and how to intervene to protect soil quality.

It thus sought to address the fact that there was no cost-effective and reliable method for assessing soil quality on a large scale previous to the project and make an important contribution to the achievement of the overall goals of the EU Thematic Soil Strategy.


The MEDAPHON project successfully built and tested a sound soil monitoring tool called the EDAPHOLOG System. This system, tested at lab level, allows covering the whole methodological process of the biological monitoring of soils: sampling, data collecting and handling, data evaluation and publication.

The EDAPHOLOG System uses innovative sampling probes to continuously monitor biological activity of soil dwelling microarthropods. The system is based around counting micro-arthropods entering mesh tubes in the soil – soil pin traps. The project developed a new sensor to accurately count the animals and was able to classify trapped mesofauna into functional groups such as bacterial feeders, fungal feeders, plant feeders, predators and omnivores.

In response to a challenge facing accurate monitoring of microarthropods in the soil, the project developed devices to prevent soil particles entering the tubes and being counted erroneously. Techniques to prevent this included use of a small pot within the metal tube and surrounding the mesh tubes with clay balls held in place with another plastic mesh.

The project also developed an electro-technical device using copper-zinc electrodes for estimating microbiological activity in soil with different moisture content. The laboratory tests showed significantly different readings from control soils and sterilized soils. This suggests that the device can differentiate levels of soil microbial activity and provide greater soil biological activity analyses than has previously been possible.

A data transmission system was developed in parallel with the sensors. This was made up of radio transmitters, data loggers, a central database, controlling software and a Java web application, Edaphoweb. This provided for GIS-based mapping, data analysis and internet-based publication. Testing of this system using the 200 probes across 50 sites demonstrated the feasibility of large-scale, real-time monitoring of soil quality and identification of problem locations.

The device can operate for several months without human intervention, as monitoring data are transmitted via internet and sensors remotely controlled. This user-friendly and cost-efficient technology should moreover facilitate improved knowledge of which soils are at most risk of degradation and which therefore require protecting interventions, showing great potential for improving approaches to soil protection in the EU.
