The outcomes from various 5- and 8-year certified organic trials in blackberry and blueberry, respectively, are reviewed.
Weed mat was the most economical method of weed control, but altered nutrient levels and irrigation requirement.
High-pH municipal compost was effective when used as part of a mulch, but not as a pre-plant amendment in blueberry.
Fertilizer source had little effect on yield and quality in blackberry, but was important for yield in blueberry cultivars.
Treatments affected growth, yield, and economic returns; the best had yields similar to conventional production.
