This 4\uffe2\uff80\uff90year on\uffe2\uff80\uff90farm study reports the effects of different agricultural practices on yield and soil organic carbon (SOC) in kiwifruit and apricot orchards grown in a Mediterranean area. Groups of plants under local orchard management (LOM,\uffc2\uffa7

) practices (i.e. soil tillage, removing of pruning residues and mineral fertilisers) were compared with plots under soil\uffe2\uff80\uff90protecting orchard management (SPOM) actions (i.e. cover crop, no\uffe2\uff80\uff90tillage, compost application and mulching of pruning residues). In the SPOM blocks fertilisation rate was based on plant demand and irrigation volumes calculated on the evapotranspiration values, while they were empirically calculated in the LOM plots. Results show that yield was 28\uffe2\uff80\uff9350 per cent enhanced by SPOM practices while SOC remained close to the initial values. In comparison with LOM plots, changed practices increased up to 28\uffe2\uff80\uff9390 per cent the amount of P and K, and 13 per cent that of N annually incorporated into soil increasing their reservoir in the soil. The study demonstrates that appropriate land management can increase the mean annual carbon soil inputs from about 1\uffc2\uffb75 to 9\uffc2\uffb70\uffe2\uff80\uff89t\uffe2\uff80\uff89ha\uffe2\uff88\uff921 per year.

Isotopic signatures (\uffce\uffb4 13 C) are used to assess the C origin of SOC or SIC. However, as measuring SOC and SIC contents, measuring \uffce\uffb4 13 C SOC and \uffce\uffb4 13 C SIC on a non\uffe2\uff80\uff90pretreated aliquot remains a challenge. Thermal analyses, like the Rock\uffe2\uff80\uff90Eval (RE) analysis, are promising to quantify SOC and SIC in a single analysis, but, to our knowledge, no development was conducted to assess \uffce\uffb4 13 C SOC and \uffce\uffb4 13 C SIC . We coupled a RE device to an isotopic gas analyser (Picarro) to continuously measure \uffce\uffb4 13 C CO2 and approach \uffce\uffb4 13 C SOC and \uffce\uffb4 13 C SIC . We hypothesised that different carbonate mineralogies and/or crystal sizes in SIC involve fluctuations of the \uffce\uffb4 13 C CO2 . Two calcareous soils, a lithogenic (calcite) and a biogenic (snail shell) carbonate, and five calcite/shell mixes were analysed with the RE\uffe2\uff80\uff90Picarro setup. Two distinct \uffce\uffb4 13 C CO2 values were obtained before and after 650\uffc2\uffb0C and were consistent with the \uffce\uffb4 13 C SOC and \uffce\uffb4 13 C SIC obtained by EA\uffe2\uff80\uff90IRMS. The fluctuations of \uffce\uffb4 13 C CO2 above 650\uffc2\uffb0C were higher with calcite/shell mixes than with pure carbonates. A \uffce\uffb4 13 C CO2 fluctuation >\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff890.2\uffe2\uff80\uffb0 could be a pertinent indicator to detect mixes of carbonate with different \uffce\uffb4 13 C in soils. The RE\uffe2\uff80\uff90Picarro setup is promising to assess SOC and SIC contents, \uffce\uffb4 13 C SOC and \uffce\uffb4 13 C SIC and detect mixes of carbonate with different origin on a non\uffe2\uff80\uff90pretreated aliquot. Development is needed (i) on more soil and carbonate samples and (ii) to improve the precision and accuracy of the RE\uffe2\uff80\uff90Picarro setup.
