In the last few decades,the use of environmental radionuclides,particularly caesium-137(^(137)Cs),represented one of the most valid methods for estimating soil ***,the cost associated with the use of the equipment needed for radiometric analyses is still high and,for this reason,finding more easily measurable indicators can be *** is a strong correlation between^(137)Cs,organic carbon(OC),nitrogen(N)and water soluble phenols(WSP)exists,indicating the latter parameters as possible early indicators of soil *** on the above assumptions,the main purpose of this work is to identify specific soil chemical parameters able to indicate early triggering of soil ***,several soil parameters such as pH,electric conductivity(EC),WSP,OC,N and C/N have been evaluated against^(137)Cs and on a comparative *** addition,since the rate of soil erosion depends on the degree of coverage and canopy structure,two different tree species(Pinus nigra laricio *** Fagus sylvatica L.)have been considered in this contribution in which ten different scenarios of forest management have been *** results show that the reduction in tree cover of managed sites triggers erosion and nutrient loss *** has been observed that the loss of^(137)Cs,compared to the control areas,is closely correlated with those of WSP,OC and *** parameters(WSP,OC and N),more easily assessable,can be a valid tool to understand easily,triggering of erosive phenomena.
