“…Quilchano et al [28] observed high standard deviations for values of SOC, N total , and C/N ratio; the annual fluctuations of these parameters (mainly SOC content) are attributed to the autumnal fall of litter (seasonal organic inputs). The standard deviations for the rest of the parameters are lower and the significant differences observed in the limed subplot in relation to the no-limed one should be attributed to the effect of liming (except for the available P, given that availability of P is also influenced by other soil properties, as the soil pH, inputs of organic residues, and/or the presence of free sesquioxides [15].…”

“…Dominant soils are cambic Umbrisols [25], equivalent to the association typic Haplumbrepts in the Soil Taxonomy classification system [26] and Leptosols. These Umbrisols are usually deep and have a non-permanent organic layer O of litter accumulation; a deep and dark A h horizon (thickness ≥40 cm) with low bulk density (0.60-0.70 Mg m −3 ); and a B w horizon, sometimes not well developed or detectable (masked by the high content of SOM; [27,28]), increasing the bulk density to 1.0 Mg m −3 (measured to −50 cm soil depth) downward.…”

Deciduous oak coppices (Quercus pyrenaica Willd.) of the "Sierra de Gata" mountains (central western Spain) are located on acid rocks and subjected to annual rainfall higher than 700 mm year −1 . Accordingly, the soils are acidic (soil pH is often below 5.0) and feature the presence of Mn 2+ and Al 3+ in the exchangeable complex. The aim of the present study was to assess the response of these soils to the addition of a lime residue from a sugar beet mill to reach pH values close to 7.0 and 6.0 with in situ and in vitro experiments, respectively. Initially, the quality of the lime by-product was evaluated, which showed content close to 75 % CaCO 3 . Based on that analysis, calculations were accomplished to determine the dose of lime by-product necessary for achieving the targeted soil pH. We first performed an in vitro liming experiment, incubating 0.50 kg soil (0-20 cm layer) with 23.92 g CaCO 3 kg −1 soil (20 °C and soil moisture equivalent to that of field capacity). Subsequently, another experiment was done adding an equivalent quantity of sub-product in lieu of the pure CaCO 3 ; the factors monitored were: soil pH, exchange acidity, CEC, and exchangeable bases, every 24 h. The in situ experiment was performed in a forest plot located in Western Spain (Navasfrías), liming with 16.0 Mg DM by-product ha −1 (September 1999). Soil samples (two depths: 0-10 and 10-20 cm) were taken from both the control and the experimental forest plots for monitoring the liming effect. Sampling dates were September

-To face the lack of information of C content in the main forest ecosystems pools from Spain and Latin America, this study compares C pools of three forest ecosystems: a tropical deciduous forest in Mexico, a tropical wet forest in Cuba and a temperate forest in Spain. The Cuban tropical wet forest had the highest total ecosystem C content (190 Mg C ha −1 ), of which 62% was in the aboveground biomass; followed by the Spanish temperate forest (150 Mg C ha −1 ) with around 75% of total C content was within soil. The Mexican tropical deciduous forest had the lowest total ecosystem C content (82.6 Mg C ha −1 ), of which 51% was in the soil. Tropical forests can not guaranteed sequestered C if the forest programs do not consider aboveground biomass protection. In contrast, temperate forests with slower C sequestration rate by means of soil stabilization are less vulnerable to forest programs.Résumé -Comparaison du pool de C dans trois écosystèmes forestiers d'Espagne et d'Amérique latine. Ce travail fait une comparaison entre les teneurs du C des sols appartenant à trois forêts : une forêt caducifoliée tropicale au Mexique, une forêt tropicale à Cuba, et une troisième forêt tempérée en Espagne. La forêt tropicale mexicaine a la plus basse teneur en C (82.6 Mg C ha −1 ) dans l'écosystème, 51 % dans le sol ; la forêt tropicale cubaine a la plus haute teneur en C (190 Mg C ha −1 ) dans l'écosystème, 63 % concentré dans la biomasse ; la forêt espagnole a 150 Mg C ha −1 dans l'écosystème, 75 % dans le sol. Les forêts tropicales ne peuvent pas garantir la permanence de la capture du C si l'aménagement de la forêt n'a pas pris en compte la protection de la biomasse aérienne ; par contre, les forêts tempérées, avec un faible taux annuel d'immobilisation du C par le sol, sont moins sensibles à l'aménagement des forêts, puisque la plus grande partie du C est concentrée dans le sol. biomasse / C des sols / Cuba / Mexique / Espagne

Nutrient dynamics on a precipitation gradient in Hawai'i

We evaluated soil and foliar nutrients in five native forests in Hawai'i with annual rainfall ranging from 500 mm to 5500 mm. All of the sites were at the same elevation and of the same substrate age; all were native-dominated forests containing Metrosiderospolymorpha Gaud. Soil concentrations of extractable NO-N and PO-P, as well as major cations (Ca, Mg, and K), decreased with increasing annual precipitation, and δN values became more depleted in both soils and vegetation. For M.polymorpha leaves, leaf mass per area (LMA) and lignin concentrations increased significantly, while δC values became more depleted with increasing precipitation. Foliar phosphorus, and major cation (Ca, Mg, and K) concentrations for M.polymorpha all decreased significantly with increasing precipitation. For other native forest species, patterns of LMA, δC, and δN generally mirrored the pattern observed for M. polymorpha. Decreasing concentrations of available rock-derived nutrients in soil suggest that the effect of increased rainfall on leaching outweighs the effect of increasing precipitation on weathering. The pattern of decreased foliar nutrient concentrations per unit leaf area and of increased lignin indicates a shift from relatively high nutrient availability to relatively high carbon gain by producers as annual precipitation increases. For nitrogen cycling, the pattern of higher inorganic soil nitrogen concentrations in the drier sites, together with the progressively depleted δN signature in both soils and vegetation, suggests that nitrogen cycling is more open at the drier sites, with smaller losses relative to turnover as annual precipitation increases.
