AbstractIn this study we evaluated the influence of two weed control management systems, integrated (IS) vs. organic production (OS) on biological properties of soil within New Zealand apple and kiwi fruit orchards. The OS used weed suppression within the rows by application of green-waste compost once a year (certified by BioGro), whereas in the IS weeds are controlled within the rows by regular herbicide applications. Total C and N, active carbon (AC) and enzymatic activities: dehydrogenase (DHA), ß-glucosidase (ß-Glu), diphenol oxidase (DphOx) and microbial biomass carbon (MBC) were determined in soils of both orchards systems at 0-5, 5-10 and 10-30 cm depth. In apple orchard soils, values of TOC, ß-Glu activity and AC were significantly higher under OS than under IS at all depths. Particularly, ß-Glu activity was three fold higher in OS in the superficial layers (0-5 and 5-10 cm). Nitrogen values were significantly greater in OS than in IS until 10 cm depth. DHA activity was also significantly higher in OS than in IS within the superficial layers (0-5 and 5-10 cm). In the kiwifruit orchard, DHA activity seemed to be the most sensitive biological parameter to indicate differences between treatments; values of this activity in OS were statistically higher at all depths. Values of ß-Glu were also higher in OS, with statistical differences in 0-5 and 5-10 cm depth. For both types of orchards, OS improved the biological soil status. We also corroborate that DHA and ß-Glu are good indicators of the improvement of soil quality caused by the OS.
