I have some soil and organic matter samples of forest ecosystems. My research budget will be very limited, so the cost of soil/organic matter analysis should be minimized. Does anyone have any recommendations for the selection of the analytical soil properties that is suitable?
On the main Chernobyl studies, scientists have concluded that to predict the transfer of radioactivity in the soil-plant is very important to consider the following properties of the soil - the percentage of sand, silt and clay in the soil and soil moisture. This is reflected in the publications. Based on these parameters there is a table of coefficients of transitions radioactive cesium and strontium from soil to plants.

Many thanks Tatiana!
I will read the recommended publications. Particle size distribution is very important variable.
Also recently I have found another one on this subject:
Nimis, P.L. 1996. Radiocesium in Plants of Forest Ecoststems. Studia Geobotanica 15: 3-49.
Dear Hidayet,
I guess that cesium contamination and its mobility in the forest soil is a very valuable primary parameter for its transfer to plants (first of all, mushrooms). All you must do is to measure cesium radioactivity by a scintillation counter in digests of soil. Large number of samples can be treated and evaluated parallely by the method we published
Bartoš,P.; Macášek,F. : Desorption techniques for determination of metals mobility in soils, Sci. World J. 2, 573-577 (2002)
and you can find its full text in my RG page.

Did you analyse the organic carbon content in your soils? I propose you to have a look at the following paper:
Tesfaye,T., Onda,Y., Kato,H., Wakiyama,Y., Mizugaki,S., Hiramatsu,S.(2013) The relationship of soil organic carbon to 210Pbex and 137Cs during surface soil erosion in a hillslope forested environment., Geoderma, 192,doi:10.1016/j.geoderma.2012.08.030
