A 3-year study on the Central Coast compared conventional and organic Chandler strawberry production systems on former Brussels sprouts land. Soil conditions, arthropod dynamics, soil microorganism populations and plant response factors were monitored and compared in both systems. Yields were significantly lower in the organic production system all 3 years, but the margin progressively narrowed. Price premiums for organic fruit permitted favorable per-acre returns for this system. Further research on ecological processes, improved practices and farm trials is needed to make organic systems more successful.
