To design best and available for concrete region, landscape and farm conditions agrotechnologies and farming systems, we should identify and analyse key limiting soil agroecological functions that determine crop current state and biological yield, farming and designed technology profitability. The objectives of the session are to discuss (1) how to identify and analyse the key limiting soil agroecological functions, (2) how to optimize their current and predicted state with minimum probability of unacceptable environmental and economic risks, and (3) how to transfer soil quality, function and processes assessments between concrete field, farm and region scales.
C3.2 - Soil and Water Conservation
C3.2.1 - Managing and remediating floodplain and wetland soils
This sessions aims to understand how human impact, in terms of management and remediation, influences soil physical, chemical and biological processes in floodplain and wetland environments, both in inland settings and the coastal zone.
C3.2.2 - Soil management in organic production and agroecology
There is a growing interest in organic production all over the world. The main attractive of organic production is the decrease in food contamination with agrochemicals associated with plant protection, which can also potentially affect soil microbiota and soil health. The restrictions for use of chemical fertilizers in organic agriculture is a matter of debate; on the one hand, there are the questions of soil contamination with heavy metals and water contamination with nitrates and phosphates; on the other hand, most grain crop agriculture may not be sustainable without chemical fertilizers because of the large extraction and export of nutrients. High level discussions, based on science and evidences of both organic and conventional agriculture are welcome.

C3.3 - Soils and land use Change
C3.3.1 - Nitrogen use efficiency (NUE) in tropical soils
Nitrogen is a key nutrient for crop production but it is also associated with environmental problems, especially water, but also air contamination. The environmental questions have dominated the agenda of discussions on agricultural nitrogen in temperate climate regions. In the tropical regions nitrogen fertilizer use is not as intensive so far. What we can learn from the temperate soil experience and what are the particularities of tropical soils regarding NUE is the subject of this Symposium.
C3.3.10 - Beneficial management practices for sustaining soil fertility
Proper management of soil fertility for sustaining soil productivity is a century-old topic and is one that deserves further discussion.

the excess of reactive nitrogen in many parts of the world are cause of concern because of the negative environmental impact. On the other hand, nitrogen may lack in some regions to sustain agricultural production. A group of scientists around the world put together an initiative to assess nitrogen budgets and management and mitigation practices, and to propose public policies.
C3.3.9 - Management of soils recently impacted by volcanic activity
In different areas of the planet, volcanic soils are an important basis for food production. The world area of Andisols are not very extensive, but are very used and increasingly under populational pressure.

C3.5.3 - Frontier of soil quality evaluation after remediation of contaminated field
Soil quality is defined as the soil ability in maintaining biodiversity and water and air quality through ecosystem. However, soil degradation mainly caused by various contaminations from urban activities or misuse of agriculture gradually becomes a crucial issue of life and environmental sustainability in lowering soil quality globally. Management strategy is important for abovementioned soil degradation which is mainly from soil contamination. However, soil quality evaluation and soil remediation seem separated discipline in the past.
C3.5.4 - Antibiotics and their resistance in agricultural food production
The growing recycling of wastes, the use of manures of animals of intensive production systems and use of agrochemicals have led to increasing additions of antibiotics to soils.
