Agroecological optimums concerning saturation with calcium of soils contaminated by 137Cs and 90Sr

134Cs uptake by four plant species and Cs–K relations in the soil–plant system as affected by Ca(OH)2 application to an acid soil

“…These findings are in agreement with previous studies that reported similar changes in 134 Cs concentration in plants due to soil liming (Jackson and Nisbet, 1990;Lembrechts, 1993;Nisbet et al, 1993;Putyatin and Seraya, 2007;Choi et al, 2008;Monna et al, 2009). However, the variability of 134 Cs plant concentration is much lower than that observed in a previous experiment (z40 for radish roots and z200 for cucumber fruits) when six plants were grown on eight different mineral soils (Skarlou et al, 1996).…”

“…Letter in common indicates lack of significant difference (Tukey's HSD test, a < 0.05); comparisons are valid within each plant part (edible or vegetative). (Lembrechts, 1993;Valcke et al, 1997;Putyatin and Seraya, 2007;Choi et al, 2008). Accordingly, the findings of the present study indicate a very strong effect of lime application in the acid sandy soil on 134 Cs plant uptake that is apparently also influenced by the plant species.…”

“…Most of the existing evidence suggests that there is a correlation of Cs uptake with soil pH, clay content, soil potassium (K)-status and clay minerals (Schuller et al, 1988;Skarlou et al, 1996Skarlou et al, , 1999Gerzabek et al, 1998;Massas et al, 2002;Kruse-Irmer and Gianni, 2003;Rahman and Voigt, 2004;Melnitchouck and Hodson, 2004). Liming of acid soils is also reported to provide an effective countermeasure to reduce Cs availability to plants (Jackson and Nisbet, 1990;Lembrechts, 1993;Nisbet et al, 1993;Avery, 1996;Putyatin and Seraya, 2007;Monna et al, 2009;Zibold et al, 2009).…”
