Spatial variability of soil organic carbon stock in an olive orchard at catchment scale in Southern Spain

Soil organic carbon and its labile fractions in the conditions of water erosion on arable land of Chernozems area

“…In the case of the HC, it is not just about a more marked vertical shift in the waterextractable OC fractions, but due to the higher TOC and clay contents, which contribute to water retention, the more pronounced their contents fluctuate in the soil profile. The spatial variability of the SOC is, thus, not only in correlation with the geomorphological variables (among others, the topographic moisture, index of sediment transport or tillage erosion) (Gómez et al 2023), but also with the current properties of the given soil.…”

Agroforestry olive orchards for soil organic carbon storage: Case of Saiss, Morocco

“…In the Mediterranean region, soil carbon may decrease by up to 50 % in olive groves, compared to adjacent areas with natural vegetation [ 43 ]. A recent study by Gómez et al [ 44 ] shows that soil organic carbon stock was on average 4.14 kg m −2 in olive orchard catchment under Mediterranean rainfall conditions. It was lower than soil organic carbon stock reported in olive orchards.…”
