“…compared with mineral horizons to lime and wood-ash treatments is in part due to the fact that Ca is applied to the upper organic horizons and takes time to reach the mineral soil and 50% of our studies were 5 years or less after application. Recycling of Ca by forests and low leaching rates are thought to contribute to much of the added Ca being held in organic horizons rather than leaching into lower mineral horizons (Cho et al 2012;Morrison and Foster 2001), as demonstrated in an in situ isotopic tracing experiment in which tracers were initially strongly held in the litter layer but over time were very slowly vertically transferred down through soil horizons (van der Heijden et al 2013). This recent research explains the much greater increase in pH in the mineral soil 15 years after application than when sampled 5 years after application (Moore et al 2012).…”

“…Similar to the bootstrap analyses of pH, the major influence on BS response was soil type and the second strongest predictor was time since treatment (trial duration). With 27% of trials in the dataset being short-term studies (4 years or less in duration), we can assume that the time required for Ca and Mg to vertically progress to the mineral horizons was insufficient (van der Heijden et al 2013) and that the short-term lack of effects on BS in the mineral horizon would not be indicative of long-term effects. In contrast to pH, wood-ash trials produced a larger BS effect response than lime, which may be due to the solubility of the varying treatments.…”

Liming and wood-ash addition have long been used to attenuate the effects of acidic deposition on forest soils with the goal of promoting tree growth. We performed quantitative meta-analyses of treatment studies from managed forest ecosystems to assess general tendencies of effects of treatment on seven selected measures of performance thought to reasonably reflect the effects of Ca-addition treatment. We retrieved over 350 independent trials from 110 peer-reviewed liming and wood-ash addition studies that were integrated to determine soil pH, base saturation (BS), tree foliar Ca concentration, tree growth, ectomychorrhizae root colonization, soil C-to-N ratio, and microbial indices. The results were quantified through three separate metaanalysis effect size metrics: unweighted relative values and two weighted metrics, Hedges' d and ln R. A surprising number of treatment trials (22%-85%) reported no significant effect, and soil pH and foliar Ca appeared more responsive to liming than to wood-ash addition, whereas BS and tree growth appeared more responsive to wood-ash addition. For six of the seven parameters, estimated mean effect sizes were similar in magnitude and positive in direction for all three meta-analysis metrics. Regression tree optimal models explained 38% of the variation in pH, 47% of the variation in BS, 51% of the variation in foliar Ca concentration, and 26% of the variation in tree growth. The largest predictors of effect size, within our selected group, were as follows: soil type for pH; soil type, trial duration in years, and species (hardwood or softwood) for BS; treatment dose and type for foliar Ca concentration; and trial duration, initial soil pH, and tree species for tree growth. This analysis shows that Ca additions are not universally beneficial and provides insight into when Ca additions to forest soils are likely to be most effective.Résumé : Le chaulage et l'ajout de cendre de bois sont utilisés depuis longtemps pour atténuer les effets des dépôts acides sur les sols forestiers dans le but de promouvoir la croissance des arbres. Nous avons réalisé des méta-analyses quantitatives des essais de traitement dans des écosystèmes forestiers aménagés dans le but d'évaluer les tendances générales des effets des traitements sur un choix de sept mesures de performance qui devraient raisonnablement refléter les effets d'un apport de Ca. Nous avons retrouvé plus de 350 essais indépendants provenant de 110 études portant sur le chaulage et l'ajout de cendre de bois révisées par les pairs. Ces essais ont été intégrés pour déterminer : le pH du sol, la saturation en bases (SB), la concentration du Ca foliaire des arbres, la croissance des arbres, la colonisation des racines par les ectomycorhizes, le rapport C à N du sol et des indices microbiens. Les résultats ont été quantifiés à l'aide de trois métriques distinctes des méta-analyses ayant trait à l'ampleur de l'effet : les valeurs relatives non pondérées et deux métriques pondérées, d de Hedges et lnR.

“…The decrease in d 26 Mg leaf demonstrates that leaf Mg was taken up preferentially from the dissolving dolomite rather than from soil exchangeable Mg (Opfergelt et al, 2014). This result is also quite interesting in light of the results of Van der Heijden et al (2013), who showed no change in the d 26 Mg leaf in the 2 yr after labeling with 26 Mg of the exchangeable Mg store of the humus layer of a very acid soil. It suggests that the translocation of Mg from soil to leaf may be reduced when the soil-available Mg level is too low.…”

“…In 2010, exchangeable Mg pools for the 0‐ to 60‐cm layers were 48 kg ha −1 in the control catchment and 137 kg ha −1 in the limed catchment; this difference represents 65% of the liming input. Trees should have taken up about 3 kg ha −1 yr −1 of Mg (Van der Heijden et al, 2013), which represents 20 kg ha −1 of Mg from 2004 to 2010 (about 5% of the liming input). According to this budget, the Mg taken up by trees should mainly originate from dolomite.…”

Liming with Ca and Mg carbonates is commonly used to reduce soil and stream acidity and to improve vegetation growth and nutrition in forests. Ten years ago, dolomite lime was experimentally applied to a forest catchment on granite in the Vosges Mountains (northeast France), which is characterized by acid soils and drained by an acid stream. The average Mg isotope composition of the dolomite lime (-1.75‰) was low compared with that of tree foliage (-0.70‰), granite and deep soil layers (-0.40‰), and stream water (-0.80‰) in the control catchment. After liming, the exchangeable Mg concentrations in surface soil layers, which were initially very low, increased, and the Mg isotope composition decreased (up to -0.60‰). The decrease was smaller in deeper layers but not in proportion to the increase in exchangeable Mg content, suggesting contributions from mineralization of organic matter and/or displacement of exchangeable Mg from surface layers. Before application, Mg concentration in beech and fir leaves was low, and that of 1-yr-old fir needles was lower than that in current needles. Internal Mg translocation within fir needles also resulted in a lower δMg of older needles. Three years after dolomite application, the Mg isotope composition of plant leaves was lower than that in the control catchment; this decrease (up to -1.00‰) was attributed to direct uptake of Mg from dissolving dolomite. Liming doubled the concentration of Mg in the stream, whereas the Mg isotope composition decreased correspondingly from -0.80 to -1.20‰, indicating a fast transfer of dolomite Mg to the stream. Our findings indicate that monitoring of δMg may be a promising tool to study the fate of dolomitic inputs in terrestrial and aquatic ecosystems.

“…At this point, the mobility of the element seems to be decisive. Van der Heijden et al (2013) [ 33 ] observed a higher concentration of 44 Ca in the root system in beech ( Fagus silvatica L.), associated to the low mobility of Ca and to physiological constraints in the phloem and the higher affinity of Ca for cation exchange sites, such as in the xylem cell wall [ 47 ].…”

This work quantifies Fe uptake in young citrus trees, its partitioning among plant compartments, and the contribution of the Fe absorbed from fertilizer to the development of new tissues. A soil pot experiment was conducted using 4-year-old clementine trees (Citrus clementina Hort ex Tan), and a dose of 240 mg Fe was applied by labeled fertilizer (92% atom 57Fe excess). Plants were uprooted at five different phenologic states: end of flowering (May 15), end of fruit setting and fruit drop (July 1), two fruit growing moments (August 1 and October 15), and at complete fruit maturity (December 10). The Fe accumulated in the root system exceeded 90% of the total Fe content in the plant. All organs progressively enriched with 57Fe (8.5–15.5% and 7.4–9.9% for young and old organs, respectively). Reproductive ones reached the highest increase (111% between May and October). 57Fe enrichment from woody organs reflects an increasing gradient to sink organs. The root system accumulated 80% of the Fe absorbed from the fertilizer, but the young organs accumulated relatively more Fe uptake during flowering and fruit setting (15.6% and 13.8%, respectively) than old organs (around 9.8%). Although iron derived from fertilizer (Fedff) preferably supplied young organs (16.7–31.0%) against old ones (2.5–14.9%), it only represented between 13.8% and 21.4% of its content. The use efficiency of the applied Fe (FeUE) barely exceeded 15%. The lowest FeUE were found in young and old organs of the aerial part (1.1–1.8% and 0.7–1.2%, respectively). Since the pattern of the seasonal absorption of Fe is similar to the monthly distribution curve of the supplied Fe, it is recommended that the application of Fe chelates in calcareous soils should be performed in a similar way to that proposed in this curve.
