International Conference
27–28 August 2012, Tartu, Estonia
Humus forms and biologically active compounds as indicators of pedodiversity

Second announcement


The conference is held on the occasion of 10 years of scientific collaboration between the Institute for Agricultural and Forest Environment (IAFE, Poznan) and the Estonian University of Life Sciences (EMÜ, Tartu) on soil organic matter research.

Thematic scope

The content and distribution of organic matter in the soil profile, its composition and functioning is soil-type and site specific. Currently, a lot of data on humus concentration, pools, quality, cycling and ecology is available for most soil types. The pedodiversity of natural areas, which is basically the heritage of geological and hydrological diversity, is always more or less influenced by the flux of falling debris on or into the soil and by its transformation due to the activity of soil organisms. The interrelationship of bio- and geo-components in ecosystems is reflected in the structure of the topsoil and its humus form (epipedon or humus cover type). The activity of soil organisms may be determined on the basis of their life traces and products. Therefore, the conference is focused on humus forms and biologically active compounds of soils.


Main conference topics are:
-    Ecological and indicative aspects of humus forms
-    Biologically active compounds in soil and methods of their determination
-    Kinetics of soil organic matter decomposition and transformation
-    Spatial-temporal patterns of soil organic matter accumulation and functioning
-    Soil-type specific organic matter fabric, composition and turnover
-    Classification and taxonomy of soil organic matter and humus forms.


The conference addresses primarily researches on pedo-climatic conditions in Northern and Central Europe. Studies may cover a wide range of land uses (arable, forest, grassland), soil types (from mineral to organic soils) and properties (texture, moisture regime, acidity, calcareousness and others). As the program is focused mainly on studies of organic matter influx and its transformation in the soil, research on gas emissions from soil (or outflux) is not included into the list of conference topics.

The official language of the conference is English.
