چکیده
This study presents an evaluation of soil organic carbon (SOC) and stock (SOCstock) for the whole rooting depth (60 cm), spaced 55 months in two adjacent olive orchards with similar conditions but different tree densities: (i) intensive, planted 1996 at 310 ha−1; (ii) superintensive, 2000 1850 ha−1. was carried out to test hypothesis that plant densities will have rates accumulation SOC depth. increased significantly superintensive orchard during 55-month period, from 1.1 1.6% lane area, 1.2 1.7% area (average 0–60 a significant increase SOCstock 4.7 6.1 kg m−2.

Tree-based intercropping (TBI) systems, consisting of a medium to fast-growing woody species planted in widely-spaced rows with crops cultivated between tree rows, are a potential sink for atmospheric carbon dioxide (CO2). TBI systems contribute to farm income in the long-term by improving soil quality, as indicated by soil carbon (C) storage, generating profits from crop plus tree production a...
