“…This is because the dynamics and characteristics of the soil physico-chemistry are affected by rainfall [26]. At the driest plot (FG) the percentage of base saturation and pH of the soil epipedon (A h horizon; table I) were the highest, while the C/N ratio was the lowest.…”

-The potential nutrient return in a chestnut coppice (Castanea sativa Miller) over a period of 3 years (1991)(1992)(1993)(1994) has been established and compared with the returns found in four deciduous oak (Quercus pyrenaica Wild.) forests (1990)(1991)(1992)(1993) located in the Sierra de Gata mountains (central Spanish system). A convergence of abscission phenology patterns was observed among the different ecosystems studied, together with a delay in leaf fall at the warmest plot. This similarity is logical since the plots harbour the same deciduous species which are, however, subjected to climatological variations. The chestnut coppice was found to be more productive than the oak forests, the amounts of leaves, branches, flowers and total litterfall being significantly greater. Statistical analysis showed a highly significant correlation between the chestnut coppice and the oak forest aboveground production, ranging between 0.82 and 0.96 for the leaves and between 0.72 and 0.89 for the total litter. In general, the leaf organs of the chestnut trees showed a higher concentration of bioelements than the oaks, with N and Ca predominant in the buds, Ca and Zn in the branches, K in the fruits, and above all Fe and Cu in the other plant remains. In all the forests studied, the potential nutrient supply fluctuated over the years and depended strongly on phenological factors; above all it was found to be governed by the leaves, which contributed most to the return of mineral nutrients to the soil. The most marked potential nutrient return through the oak aerial organs occurred on the plot with the lowest rainfall, particularly with respect to P and Ca. Considering all the forest plots, the general sequence of the amount of bioelements returning with the litterfall to the soil was as follows:with the exception of one oak plot (

“…The higher pH of this epipedon was due to a reduced leaching during winter (the deep water drainage is almost non-existent; [30]). This higher pH permits the development of herbaceous legumes, favouring a better C/N ratio and increasing the speed of the biogeochemical cycles [26]. [20].…”

“…Root samples were taken from a trench (2 m 2 ) at two depth layers: 0-10 cm and 10-20 cm. The litterfall production was measured during three consecutives years, using 30 litter tramps and sampled periodically through the year [28].…”

“…The aboveground biomass was estimated by allometric equations developed for the same study site using a destructive method (five trees for each DBH class) based in the tree diameter [38]. Surface litter and soil were sampled in three different soil profiles, C concentrations in litter and soil were determined by a Carmhograph (Wosthöff) and soil C content was calculated taking in account the bulk density of each horizons [10,28]. Root samples were taken from a trench (2 m 2 ) at two depth layers: 0-10 cm and 10-20 cm.…”

-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
