Convert to organic farming
A replicated experiment in 2009 on gravelly silt loam and sandy-clay soils in Sicily, Italy (Canali et al. 2009) found higher carbon levels in the soil (11,000 mg C/kg soil) in organic compared to conventionally managed orchards (8,750 mg C/kg soil). Greater numbers and activity of soil microorganisms occurred in organic (110 mg/kg and 8 mg/kg respectively) than conventional orchards (60 mg/kg and 8 mg/kg respectively). Maximum yield was lower in organic orchards (20 t/ha) compared to conventional orchards (35 t/ha). There were 13 replications of paired organically and conventionally managed citrus orchards (crop species not specified). The study measured soil organic carbon and microbial biomass and activity.
