Shoot Sr concentrations in relation to shoot Ca concentrations and to soil properties

This work was aimed to investigate whether shoot Sr concentrations of plant species are related to respective Ca concentrations and to soil properties and to compare the Sr-Ca observed ratios (OR), defined as the quotient of the ratios Sr/Ca in shoots and in the soil solution or in the extractable form, among species and soils. Ten pasture plant species were grown in pots (1-L volume) filled with eight soils differing in the various physicochemical characteristics. Each pot received 50 mg Sr except those of the soil with the highest cation exchange capacity (C.E.C.) that received 100 mg Sr per pot. For each soil, shoot Sr concentrations of species were linearly and positively related with the respective Ca concentrations. C.E.C, organic matter content and Ca in the soil solution or in the extractable form were the only soil properties that were related, all negatively, with shoot Sr concentrations. The ratio of extractable Sr and Ca was positively and linearly related with the ratio of Sr and Ca. in the soil solution. OR was affected by both species and soils. Most of OR values of all species in all soils ranged between 0.8 and 1.5, except for the grass Agrostis capillaris which had the highest values for most of soils. This indicates that Agrostis capillaris compared to other species, takes up proportionally more Sr than Ca.

“…Sr were found to vary with soil type and be correlated with several soil properties for various crops or plant parts (Papanicolaou et al 1991). Their correlation with exchangeable (Ca + Mg) or with total exchangeable bases (Papanicolaou et al 1992) was very good (r from -0-87 to -0-92) and, on average, better than that of exchangeable Ca (r from -0 8 3 to -0-86).…”

S U M M A R YIn a glasshouse pot experiment in Athens, Greece in 1989, 85 Sr to calcium observed ratios (OR) based on the values of exchangeable Ca instead of soil Ca (OR ex Ca), were determined for crops or plant parts grown in eight soils widely differing in their physical and chemical properties. Compared to the values of concentration ratio (CRs) the values of OR ex Ca did not show as wide variation with the soil type. They were relatively constant and usually not related to soil properties. The OR ex Ca values were essentially the same as OR values for the non-calcareous soils and much smaller than the OR values for calcareous soils, considering as soil Ca in the calculation of OR, the sum exchangeable, watersoluble and CaCO 3 Ca.The values of 85 Sr/Ca + Mg observed ratios (OR ex CaMg) were just as good as the OR ox Ca values, while those of 85 Sr/Ca + Mg + K + Na (OR C1( bases) showed more variation.Highly significant (P < 001) correlations were observed between the fractions of the observed ratios OR ex Ca, OR ex CaMg and OR CX bases, for each crop or plant part tested.
