The crop nutrient balance--the comparison of nutrients applied in relation those removed by crops--is an important indicator of the sustainability performance of crop production. Deficits in the nutrient balance can limit crop yields and deplete soil fertility, and surpluses can cause economic waste
Regional Update – 25 March 2014 It’s been quite a winter up here in the Northeast. More cold, more snow than in many decades, following on the heels of a great crop year with high nutrient removals. Environment Canada forecasts a colder than normal month of March for most of Eastern Canada, and NO

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. Population density is high; land development is taking land from agriculture and impinging upon agricultural activities. Turfgrasses for residential lawns, recreational parks and golf courses occupy a substantial area of land and vary widely in intensity of nutrient use.
