“…In our study, increasing levels of bioavailable Sr in the soil did not affect the concentration of Sr in the stems of oats grown on S-L soil ( p > 0.05), while a significant increase was visible for those in C-L soil ( p < 0.05) (Figure B). This absence of uptake response at increasing levels of external Sr in S-L soil was not surprising and has been reported in the literature for different soil types …”

“…At the excavation time, there were no significant differences in the stem dry weight among treatments and among soils ( p > 0.05 in both cases), with an overall average dry weight per stem of 131 ± 26 mg. Despite the difference in the bioavailable Sr content between the two soils and the fact that Sr uptake normally tends to be higher in soils with a sandy texture, ,, the Sr content of oat stems in control soils (2.83 ± 0.32 μg and 3.14 ± 0.24 μg per plant on S-L and C-L soil, respectively) was unaffected by the soil type ( p > 0.05). The soil-to-plant transfer factor (TF) was significantly higher in the S-L than in C-L soil ( p < 0.01), with an overall average of 3.44 and 1.07, respectively, in line with the values of soil bioavailable Sr. On the contrary, no differences in the TF among treatments were generally observed ( p > 0.05) (Table S7).…”

This result suggests that Sr-uptake depends not only on its concentration in the soil but also on additional variables: although we have not specifically investigated them, we might speculate that they include the percentage of organic matter, the cation exchange capacity, the availability of other cations (Ca, Na, S, and Mg), and rhizosphere processes. − …”

The Sr/Sr ratio of a produce is generally linked with the soil geological features of the growing areas. This study aimed at assessing to which extent the addition of external Sr by agricultural practices, like irrigation and mineral nutrient supply, influences this relationship. In a first experiment, oat plants in two soils reflected the Sr/Sr of the soil. However, this link was significantly altered at increasing levels of external Sr soil supplies. In a second experiment, apple trees transplanted in pots modified their original Sr/Sr, which became progressively closer to the soil Sr isotope ratio. The addition of tap water and fertilizers, with different Sr isotopic signatures, slightly affected plant Sr/Sr. Results confirm the potential of the Sr/Sr ratio as a geographical tracer of agricultural commodities, but whenever the range of Sr/Sr variability among soils from different geographical areas is narrow, the influence of external Sr-sources may smooth over these diversities.

The uptake of (137)Cs and (90)Sr by six varieties of spring wheat (Triticum aestivum) was compared in field trials on land contaminated by the Chernobyl accident. All the experimental varieties are officially adopted for agricultural use in Belarus and are used in large-scale production. Under identical conditions of nutrition, the productivity of the varieties varied significantly by a factor of 1.3. The extent of (137)Cs and (90)Sr accumulation by wheat grain, quantified as the concentration ratio, differed between the varieties by as much as a factor of 1.6, for both radionuclides. There was a significant linear positive correlation between the (90)Sr activity concentration in grain and straw, and the calcium concentration. The correlation between (137)Cs and potassium was not significant. The results suggest that certain varieties of spring wheat used in normal agricultural practice accumulate less (137)Cs and (90)Sr into grain than others. Some spring wheat varieties accumulated relatively less (137)Cs, but did not accumulate less (90)Sr. One variety, Quattro, had a significantly lower uptake of both (90)Sr (for grain) and (137)Cs (for both grain and straw) than that of the other varieties tested. The reduction efficiency achieved by the use of these varieties, however, is not as high as that achieved by soil amelioration techniques in the past. Nevertheless, since there are no additional costs or production losses associated with these varieties, their use in the contaminated areas is worth considering as a simple, practical, and effective contribution to reducing the uptake of both (90)Sr and (137)Cs and allowing farmers to produce food-grade grain.
