  abstract = {{C}onservation agriculture ({CA}) is one strategy with which both sustainability and productivity can be achieved by improving soil health. {H}owever, linkages between practices, soil health and cropping system performance remain poorly disentangled. {W}e assessed the relationships between soil health and cropping system performance for three maize-based cropping systems in {N}ew {C}aledonia. {T}wo {CA} systems, one with direct seeding into a mixed species dead mulch ({CA}-{DM}) and one into a stylo living mulch ({CA}-{LM}), were compared to a conventional tillage ({CT}) system. {CA} vs. {CT} experiment started in 2011, whereas the differentiation between {CA}-{DM} and {CA}-{LM} was initiated in 2017 only. {I}n 2018, soil health was evaluated using {B}iofunctool ({R}), a set of ten in-field tools that assess soil carbon transformation, structure maintenance and nutrient cycling functions. {T}he performance of the three cropping systems were assessed by monitoring weeds, maize growth and yield components. {S}tructural equation modelling ({SEM}) was used to disentangle the links between agricultural management, soil health and cropping system performance. {S}oil structure maintenance and nutrient cycling functions were higher under {CA}-{DM} and {CA}-{LM} than under {CT}, and carbon transformation function was higher under {CA}-{DM} than under {CT} and {CA}-{LM}. {O}verall, the soil health index ({SHI}) was 1.3-fold higher under {CA} systems than under {CT}. {C}ropping system management had both direct and indirect effects on soil functioning and crop productivity leading to a 1.3-fold higher yield under {CA} than under {CT}. {T}he direct and indirect effects of {CA} systems on soil health had positive impacts on ecosystem services (i.e., productivity, weed regulation and soil ecosystem services). {S}uch integrative approaches that account for the relationships and possible trade-offs between cropping system components enable a better understanding of the effects and the performance of practices, and support adaptive agricultural management.},
