prediction and accuracy maybe good in some soil types but poor in others
Remote sensing technologies
Hyperspectral cameras (airborne/ satellite)
portable systems on tractors
implemented at large scales (country) to estimate soil C stocks (C market), but not so much at field or farm scales
restricted use in soils with permanent vegetation cover
demonstrate the application in precision agriculture
educate farmers, advisors and extension services about spatial variability of soil properties, incl. SOM
use field radiometer to distinguish better the signal of the vegetation and SOM
extremely low cost

countries at large scales (e.g. France, Spain) or European level (JRC)
cost limitation, especially for large-scale and/or long-term monitoring
standardize the procedures across countries
aggregate the existing databases and conduct meta-analyses
refine the classes to better define what is too low or adequate, depending on targeted ecosystem service according to soil types
better knowledge of the starting point (for the purpose of monitoring the fate of SOM)
provide relevant guidelines for Mediterranean soils and agroecosystems
a given SOM may be considered adequate for some use, but not for others
(need to adjust to objective and also raise awareness about analytical uncertainties)
SOM quality
SOM
organic sources of input of C
confined to research or few localities/systems (high costs of determination)
more largely implemented for defining e.g. compost qualiies
few routine labs as market is reduced so far
standardize the procedures across countries
aggregate the existing databases and conduct meta-analyses
search for alternative analytical techniques (use of IR spectrometry again ?)
draw link with the functionality and potential fate of SOM (or organic inputs)
biaised dataset so far as confined to few localities/systems
Soil quality
Biological indicators
confined to research or few localities/systems (high costs of determination)
few routine labs as market is reduced so far
lack of appropriate references and guidelines
standardize the procedures across countries
aggregate the existing databases and conduct meta-analyses

more relevant at a funtional point of view than SOM content (as long as links are drawn between the indicators and the funtionalities)
multiple and possibly contradictory indicators
more focus on biodiversity than functional diversity
SOM quality assessment - (bio)chemical / (bio)physical components (Bio)chemical properties
SOM
organic sources of input of C
confined to research or few localities/systems (high costs of determination) except for elemental (CNPS) contents
more largely implemented for defining e.g. compost qualiies
search for alternative analytical techniques (use of IR spectrometry again ?)
use of techniques such as thermo-gravimetry, loss on ignition, etc...

lack of appropriate references and guidelines
current development of molecular determination of microbial biomass (and diversity index) are becoming cheaper and high-throughput
develop databases and guidelines to relate to soil functionalities
microorganisms are key players of the biogeochemical cycles but more research needed to get molecular tools that relate to specific processes in C cycling
other quite high-throughput tools available for microbial activities (MicroResp and alikes)
microbial biomass often correlated with SOM content, and hence does not add much more information
microbial activities that are most often assessed indicate a potential activity, which might be quite different in situ (temperature, humidity)

current development of molecular determination of microfauna (abundance and diversity indices) under progress
develop standardized protocoles, databases and guidelines to relate to soil functionalities for some groups (done for nematode communities)
earthworms and other groups of macro- or mesofauna are key players for incorporating C in the soil and controlling its cycling - they are easy to communicate on with farmers and public
microfauna plays a key role in regulating microbial communities and are thus more integrative of soil food web
lack of direct link with C cycling and the fate and nature of SOM

few specialists of the various groups of fauna being capable of identifying the species
build-up on what is existing for some categories of soil macrofauna or microfauna
develop molecular tools for eukaryotes
draw general relationships between ecosystem or soil functions and measurable indicators
the general relationship maybe of little significance in a local, specific context
Enzymatic activities
C cycle
P and S cycles
poorly known and standardized
refine and standardize the analytical procedures (develop ISO standard procedures)
develop kits for more high-throughput assessment (possibly used in situ ?) for those portions of these cycles that are poorly documented
further disseminate
directly related to specific processes along the biogeochemical cycles of C, P and S
largely influenced by operating conditions (notably pH) - thus rather represeningt potential activities

IV - Needs for innovation (practical and/or research) Areas needing exploration to find
new practical solutions Important knowledge gap? What research or technical innovation
needed to work towards a practical solution?
High throughput/low cost analytical techniques for determining SOM content design low-cost SOM-dedicated portable
device for field measurements by farmers or advisors (VisNIRS-based)
further assess the impact of the local conditioning of sample (water content, surface roughness) across a diversity of soils
chemometry development required that could be locally adapted and evolving
Database construction and reference values for diagnostic purposes exploit databases for defining proper
guidelines to be used for diagnostic pruposes
building of comprehensive, databases no bottleneck here
need to compile data and include relevant measurements in on-going experimental sites pr farmer's plot networks
SOM quality assessment - biochemical / biophysical components fingerprinting (synthetic approach,
rather than analytical (one property at a time)
paradigm shift required in the community of soil biochemists
mimick what is being developed in other sectors such as the food industry
Soil quality assessment - biological component functional approaches or indices lack of appropriate molecular tools
(functional genes) in soil microbial communities and soil fauna
develop such tools and mimick the approach developed in plant ecology for natural ecosystems or pastures

TABLE 3: KNOWLEDGE TRANSFER AND ADOPTION OF NOVEL TECHNIQUES FOR IMPROVING THE SOM CONTENT OF MEDITERRANEAN SOILS
I - Good existing practices underused or needing promotion Subtopic Why not implemented How to promote further? Main advantages? Risk/downsides?
Means to encourage a change in practice (see also information- communication section) Demonstration trials
with farmers' networks
lack of organized structures (extension services) to disseminate novel techniques in many European countries (advisors being mostly in the agro-industry sector)
lack of existing, structured networks of farmers in many areas and/or countries
encourage novel practices in the Best Practice Manuals / conditoning CAP subsidies
encourage extension services (or equivalent) to structure such networks
develop extension services and promote the involvement of farmers' groups
real-world conditions proof of concept
opportunity to exchange about the whole system change
has only local effects (neighbours) and requires being replicated

for advisors
has been starting with adult learning
to be implemented in schools and university (undergraduate levels)
raise the awareness on the importance of SOM and soil quality management among the people in charge of the educational programmes
promote freely available e-learning tools
education can assist further in creating an understanding of the need for change
is the only option for long-term, sustained change
it takes long and needs considerable investment (teachers need to be educated themselves)
Decision support tools for making right decisions Decision support tools (models)
to assist farmers in the right choice of techniques
to assist advisors for providing expertise
often restricted to research (too elaborated, not user-friendly for non specialist, or for occasional users)
tools to be developed for farmers and/or advisors (they should be involved in the elaboration of the tools)
novel modeling techniques (e.g. multi-agent, multi-actor, game-based) can promote the adoption/use of such approaches
comprenhensive and quantitative approach of the problem
compiling expert views that can be enriched over time
inadequacy of the model parametrization to the local conditions
lack of information about uncertainties
ex.: Operational decision tree
dedicated to SOM management
dedicated to soil quality management
the quantitative impact of numerous processes is still unknown and thus scientists are reluctant at elaborating such an operational tool
estimating the uncertainties and communicating about these
integrating soil/climate conditions, farm specificities, nature/quality of potential sources of C etc.
holistic view of the problem
assessment of the efficiency of the various strategies
see above
Knowledge transfer and sharing information to/with farmer and advisors Experience sharing
farmer self-help groups
Best Practice Manuals
cultural barriers : not easy to implement in areas or countries that have no tradition in openness and sharing experiences
model needed that suits areas or countries where there is not such an ‘open’ culture
trustworthy forum for knowledge exchange
suitable for transfer and dissemination of knowledge from research to farms
geographical constraints as self-help groups require proximity
Participatory research
involving farmers and/or advisors at all steps of the process (design/assess)
requires a change of paradigm as it assumes that new knowledge is not only coming from the scientists
requires strong involvement of all partners
communicate on positive results of participatory research (former success stories in the adoption of innovations)
trustworthy forum for knowledge exchange
suitable for transfer and dissemination of knowledge from research to farms and, reciprocally from farmers to scientists
considerably helps adoption of the
restriction to techniques that local group of farmers wish to test (need to volunteer)
