Revision Notes "Eq. 4. I recommend to replace k with j. K could result in misunderstanding (it could be mixed up with a rate constant)" We totally agree with this comment of the reviewer. Therefore, it has been changed. L. 371-372 of the new version. Please present in a new table the mean temperature and rainfall for each sub-climate regions used in the study. We acknowledge the comment of the reviewer. We decided to not to include a table with values of temperature and precipitations due to the high complexity of the Köppen-Geiger climate classification. As it is shown in the figures below (Kottek et al., 2006), each climate is defined by three letters. Second letter corresponds to precipitations and the third one to the air temperature conditions. We considered that include all this information in a table would not be so much helpful to the paper and, for that reason we decided to include only the full name of each climate (e.g. Csa (Warm temperate, dry summer, hot summer)) and referring the table to this paper of Kottek et al., 2006. Highlights  Effects of RMPs on SOC in woody crops were assessed using literature data  Average SOC sequestration rate for all RMPs was 3.8 t C ha-1 yr-1.  C sequestration rates in olive orchard ranged 1.1 (CC) to 5.3 (OA) t C ha-1 yr-1.  C sequestration rate in vineyards was 0.78 t C ha-1 yr-1 in CC management.  C sequestration rates were highest during the first years of the RMPs *Highlights (for review)

Emissions of N 2 O and CO 2 were measured following combined applications of 15 N-labelled fertiliser (100 μg N g −1 ; 10 atom % excess 15 N) and organic olive crop weed residues (Avena sativa, Ononis viscosa, Ridolfia segetum and Olea europea; 100 μg N g −1 ) to a silt loam soil under controlled environment conditions. The objective was to determine the effect of varying combinations of inorganic fertiliser and plant residues on these emissions and soil mineral N dynamics. Emissions were generally increased following application of residues alone, with 23 ng N 2 O-N g −1 soil (2 ng N 2 O-N g −1 soil mg −1 biomass) and 389 μg CO 2 -C g −1 soil (39 μg CO 2 -C g −1 soil mg −1 biomass) emitted over 28 days after addition of the Ridolfia residues in the absence of fertiliser-N. N 2 O emissions from these residue-only treatments were strongly negatively correlated with residue lignin content (r = −0.91; P < 0.05), total carbon content (r=−0.90; P<0.05) and (lignin + polyphenol)-to-N ratio (r=−0.70; P<0.1). However, changes in the net input of these compounds through application of 25:75, 50:50 and 75:25 proportional mixtures of Avena and Ononis residues had no effect on emissions compared to their single (0:100 or 100:0) applications. Addition of fertiliser-N increased emissions (by up to 30 ng N 2 O-N g −1 28 days −1 ; 123%), particularly from the low residue-N treatments (Avena and Ridolfia) where a greater quantity of biomass was applied, resulting in emissions above that of the sum from the unfertilised residue and fertilised control treatments. In contrast, fertiliser application had no impact on emissions from the Olea treatment with the highest polyphenol (2%) and lignin (11%) contents due to strong immobilisation of soil N, and the 15 N-N 2 O data indicated that residue quality had no effect on the denitrification of applied fertiliser-N. Such apparent inconsistencies mean that before the potential for manipulating N input (organic + inorganic) to lower gaseous N losses can be realised, first the nature and extent of interactions between the different N sources and any interactions with other compounds released from the residues need to be better understood.
