Regional Profile

The region has many areas with a large ratio of livestock to cropland area, leading to challenges of localized nutrient surpluses associated with managing manure as a source of plant nutrients. In addition to the crops listed above, there are many areas of fruit and vegetable production, both in field and in greenhouses, and both for fresh market and for processing. Potatoes comprise a substantial proportion of crop production in Prince Edward Island, New Brunswick and Maine.
