The Pennsylvania Association of Sustainable Agriculture (PASA) sponsored a field day on June 2 to talk about growing vegetables in a changing climate. The discussion focused on climate change, its impacts on the farming system, and strategies to effectively adapt through increasing biodiversity on the farm.
PASA’s Director of Educational Programs, Franklin Egan, provided an overview of climate change trends and projections. Dave King and others who farm 160 acres of vegetables and small fruit all sold within 25 miles of the farm, talked about their challenges and sustainable farming practices. Among them, high tunnel beds have more aphids and pill bugs in the winter, downy mildew appears earlier in the summer, weeds are not any easier to manage especially without degrading soil health, irrigation costs are rising, and deer pressure rises during droughts. Practices being continuously adapted to respond to changing conditions include a highly diversified crop production system, use of beneficial insects, crop rotations, cover cropping, and rye straw mulch.
