  abstract = {{S}ustainable horticulture depends on the integrity of soil functions, which directly depend on soil architecture affecting aggregation, root growth, as well as liquid and gas permeability. {W}e hypothesised that changes in soil architecture resulting from feedback mechanisms between management, soil organic carbon contents ({SOC}), biota and vegetation can be captured with {X}-ray computed tomography ({CT}), and that these affect the soil filtering function, which thus, can be manipulated through orchard management. {W}e compared the transport of copper, a widely used fungicide, through intact soil cores from vine rows of kiwifruit orchards under organic and integrated management. {W}e first derived 3{D}-macropore characteristics from {CT}-images, followed by leaching a pulse of copper and a tracer through the same cores. {T}he organic orchard soil had a significantly higher {SOC} content than the integrated orchard soil, and this was positively correlated with total porosity. {M}acropores (>92 mu m) were larger with a higher connectivity, but significantly fewer in the organic than the integrated orchard soil. {T}his resulted in a lower macroporosity and a better copper filtering capacity of the organic than the integrated orchard soil. {C}opper distribution was reasonably predicted when combining {SOC} contents, p{H} and macropore characteristics. {S}ignificant relationships between soil parameters and indicators of the strength of preferential flow verified that {CT}-derived macropore characteristics can be used to predict functional solute transport parameters. {T}he relevance of our results and relationships observed between macropore characteristics, functional indicators of preferential flow and the fate of copper needs verification with samples representing more soils and sites.},
