Organic cranberries are produced across the continent, with over 100 acres grown in Wisconsin. The major problems facing organic cranberry growers include weeds, insect pests, fruit rot and other fruit quality issues; but most significant is a 50% or more reduction in yield compared to conventional production. There is room for the organic cranberry market to expand, yet many growers who have tried it have given up because the price could not make up for the yield loss and costs associated with organic production. Research into improved fertilization techniques and varieties better suited to organic production could overcome the yield drop and improve the economic feasibility of organic production.
