Low input cranberry production was carried out at 4 sites (2 each for the common MA cultivars) to demonstrate: 1. reduced pesticide and fertilizer input; 2. enhanced water quality (compared to standard management); 3. ecomonic feasibility. Presented results: 1. number of insecticide applications reduced 60%, number of fungicide applications reduced 40% (at least half were copper based non-synthetics), broadcast herbicides used at less than 1/2 allowed rate (if at all), fertilizer N input reduced 30% on average; 2. reduced chemical input impacted positively on water quality; 3. crop quality was maintained but yield was reduced. Because the MA cranberry crop was down by up to 40% due to weather-related factors, crop reductions cannot be accurately assigned to cultural and management practices. The project will continue for at least 2 more years.
