“…According to Deng et al [76], in our study a positive correlation among TOC and annual precipitation was retrieved. However, a similar correlation has not been observed by other authors in Italy [38,50], which is probably due to the low annual rainfall that never exceeds 1000 mm in our sampling areas. Indeed, in arid and sub-arid agroecosystems, precipitation can stimulate plant production more than the microbial decomposition processes [64].…”

The present investigation was aimed to quantify the three principal components of the soil carbon (C) stock, namely inorganic, organic and permanganate oxidizable, in 0–5 cm and 5–30 cm soil layers, of the main Mediterranean agricultural land coverages: olive grove, olive forest, citrus grove, vineyard, arable irrigated, arable rainfed and natural soil covered by Mediterranean scrub and garrigue. We assessed the contribution of soil properties and climatic variables on soil TOC and POxC by Pearson’s correlations, multiple linear regressions, principal component analyses and variance partitioning. NAT and both olive cropping systems showed the highest TOC concentration while the other land covers showed values ranging between 8.0 and 26.6 g kg−1. Soil POxC represented between 0.5% and 2.2% of the total soil C. A large number of interrelated factors govern soil C accumulation in Mediterranean agroecosystems. Rainfall and temperature had a selective effect on soil C distribution between the sampling areas, while among soil properties, texture exerted a prominent effect, resulting in positive effects from clay and negative effects from sand. Soil POxC concentration showed a similar trend to soil TOC in all land uses although on each of them represent a different TOC portion.

“…Measured TOC and C stock levels showed similar values compared to other studies performed in Mediterranean areas [4,10,[37][38][39][40][41][42]. The average TOC content in the soils of the sampled areas was 42.9 Mg C ha −1 and fell within the range of values reported for other European countries.…”

“…The farmland soil organic carbon pool plays an important role not only in the process of global carbon 48 circulation but also as the most important material base for soil fertility [1], and has a decisive role in the 49 maintenance of cultivated land productivity, the prevention and treatment of soil erosion, the spatial and 50 temporal variation of soil respiration and its stability, etc [2]. The soil organic carbon pool in terrestrial 51 ecosystems is about 3 times that of plant carbon pools, and the organic carbon exchanged between soil and 52 atmosphere accounts for about 2/3 of the total carbon storage of surface ecosystems, which slightiy changeed 53 will have a certain impact on greenhouse gas emissions [3].…”

“…Soil organic carbon mineralization is a process in which organic substances are decomposed into 60 inorganic substances under the action of microbial degradation, providing nutrient content for crop growth 61 and releasing greenhouse gases such as CO 2 to silt loam as the proportion of soft rock increases. Moreover, the photosynthesis rate of crops and the 80 activity indexes such as antioxidant enzymes showed a trend of increasing first and then decreasing.…”

At this time, the distribution of soil particles was more uniform, the soil structure was stable, 44 and the mineralization level of unit organic carbon was lower. The research results have practical 45 significance for the large area popularization of soft rock and sand compound technology.

“…The destruction of the upper soil horizon in urbanization causes the release of part of the organic carbon in the form of greenhouse gases due to mineralization, and ruins centuries of work of natural processes which form arable land. Because of this, attention to soil organic carbon (SOC) cycle is increasing [58][59][60]. The reforestation of degraded forest lands and the adoption of recommended management practices (RMP) in farmland and cropland have been argued as effective options for carbon sequestration in soils, and both generate additional environmental and socioeconomic benefits [61].…”

Multitemporal Analysis of Soil Sealing and Land Use Changes Linked to Urban Expansion of Salamanca (Spain) Using Landsat Images and Soil Carbon Management as a Mitigating Tool for Climate Change

The lack of urban sustainability is a widespread deficiency in urban agglomerations. To achieve adequate land use, we present a methodology that allows for: 1) the identification of the impacts caused by urban expansion since 1956 to the present in Salamanca (Spain); and 2) the promotion of a more sustainable future in urban development. A multi-temporal assessment of land use was made by remote sensing, while sustainability criteria were analyzed using the multicriteria analysis (MCA) with Geographical Information Systems (GIS). In addition, we established recommendations for soil carbon management in semi-arid ecosystem soils that contribute to climate change mitigation. The results show an increase of the urbanized area from 3.8% to 22.3% in the studied period, identifying up to 15% of buildings in zones with some type of restriction. In 71% of the cases, urbanization caused the sealing of productive agricultural soils (2519 Ha), almost 20% of which were of the highest quality. In last few decades, an excessive increase of built-up areas in comparison to population dynamics was identified, which causes unnecessary soil sealing that affects the food production and the capacity to mitigate climate change by managing the carbon cycle in the soil.
