“…The SOC stock for soil groups in peninsular Spain (Rodríguez-Murillo, 2001) is 66.0 Mg ha −1 for LV and soil uses is 50.5 Mg ha −1 , 42.5 Mg ha −1 and 39.9 Mg ha −1 for AC, V and OG, respectively; and the SOC stock for Andalucía (map of SOC content in Andalusia) are 53.2 Mg ha −1 and 57.3 Mg ha −1 for LV in arable crop and permanent crops, respectively (Muñoz-Rojas et al, 2012). This is in agreement with our results, which show that SOC stock is affected by LUC.…”

Abstract. The agricultural Mediterranean areas are dedicated to arable crops (AC), but in the last decades, a significant number of AC has led to a land use change (LUC) to olive grove (OG) and vineyards (V). A field study was conducted to determine the long-term effects (46 years) of LUC (AC by OG and V) and to determine soil organic carbon (SOC), total nitrogen (TN), C : N ratio and their stratification across the soil entire profile, in Montilla-Moriles denomination of origin (D.O.), in Calcic-Chromic Luvisols (LVcc/cr), an area under semiarid Mediterranean conditions. The experimental design consisted of studying the LUC on one farm between 1965 and 2011. Originally, only AC was farmed in 1965, but OG and V were farmed up to now (2011). This LUC principally affected the horizon thickness, texture, bulk density, pH, organic matter, organic carbon, total nitrogen and C : N ratio. The LUC had a negative impact in the soil, affecting the SOC and TN stocks. The conversion from AC to V and OG involved the loss of the SOC stock (52.7 % and 64.9 % to V and OG respectively) and the loss of the TN stock (42.6% and 38.1 % to V and OG respectively). With respect to the stratification ratios (SRs), the effects were opposite; 46 years after LUC increased the SRs (in V and OG) of SOC, TN and C : N ratio.

“…Climate, use and management are highly influential in the C variability in Spanish soils (Muñoz-Rojas et al, 2012;Rodríguez-Murillo et al, 2001;Ruiz et al, 2012), mainly in semiarid regions, characterized by low levels of SOM content (∼ 10 g kg −1 ) (Acosta- Martínez et al, 2003).…”

“…Equivalent approaches at different scales were used by Rodríguez-Murillo (2001) in peninsular Spain and by Boix-Fayos et al (2009) in Murcia (SE Spain). Soil profiles were classified according to original soil profile descriptions, into 10 soil reference groups (IUSS Working Group WRB, 2006): Arenosols, Calcisols, Cambisols, Fluvisols, Leptosols, Luvisols, Planosols, Regosols, Solonchaks and Vertisols, and 7 land use types (following CLC nomenclature at level 2: "arable land", "permanent crops", "heterogeneous agricultural areas", "forest", "scrub and/or vegetation associations", "open spaces with little or no vegetation", and "maritime wetlands").…”

Organic carbon stocks in Mediterranean soil types under different land uses (Southern Spain)

Abstract. Soil C sequestration through changes in land use and management is one of the sustainable and long-term strategies to mitigate climate change. This research explores and quantifies the role of soil and land use as determinants of the ability of soils to store C along Mediterranean systems. Detailed studies of soil organic C (SOC) dynamics are necessary in order to identify factors determining fluctuations and intensity of changes. In this study, SOC contents from different soil and land use types have been investigated in Andalusia (Southern Spain). We have used soil information from different databases, as well as land use digital maps, climate databases and digital elevation models. The average SOC content for each soil control section (0-25, 25-50 and 50-75 cm) was determined and SOC stocks were calculated for each combination of soil and land use type, using soil and land cover maps. The total organic C stocks in soils of Andalusia is 415 Tg for the upper 75 cm, with average values ranging from 15.9 Mg C ha −1 (Solonchaks under "arable land") to 107.6 Mg C ha −1 (Fluvisols from "wetlands"). Up to 55 % of SOC accumulates in the top 25 cm of soil (229.7 Tg). This research constitutes a preliminary assessment for modelling SOC stock under scenarios of land use and climate change.

“…In comparison with commercial plantations, which are subject to net losses of C as a consequence of site perturbations and low inputs from litterfall [42,47], natural forests play an important role as long-term C sinks in soil and tree components [6,23,24,50]. However, disturbances can disrupt the C cycle through direct effects on tree biomass (the age-class distribution of the forest shifts to younger stands containing less C, [28]) and soil organic matter decomposition [17] and, therefore, leading to reduction in C stocks.…”

Carbon and nutrient stocks in matureQuercus roburL. stands in NW Spain

-In the present study, the distribution of C and nutrients in biomass (above-and below-ground) and soil were estimated in native Quercus robur stands in NW Spain. This information can be used to design future strategies to preserve and improve these forests, which are subjected to severe degradation as a consequence of poor management and fire damage. Biomass equations for tree components were fitted simultaneously using the data corresponding to 31 trees felled in 4 representative mature stands. The C accumulated in aerial biomass, roots, litter layer and mineral soil made up 40, 10, 8 and 42% respectively, of the C in the whole forest system. Tree biomass contained higher amounts of macronutrients than the available reserves in the soil. Stem wood was the major tree compartment for most nutrients, with the exception of Ca, which was mainly accumulated in stem bark. In comparison with commercial forest plantations in the region, particularly high amounts of nutrients were accumulated in the litter layer because of the high amounts of litterfall and higher foliar concentrations of nutrients.
