Abstract

There is no sustainable alternative to increase local food security more effective than producing more affordable quality foods locally. The Soil and Land Management Division of the Department of Forest Resources and Agrifoods, Government of Newfoundland and Labrador have identified late spring or early fall frost, low soil organic matter, sandy soil textures and soil acidity as the primary problems impacting crop production in Happy Valley-Goose Bay area. Among these factors, we have no ability to control weather and soil texture, but can effectively manage soil organic matter contents, and correct soil acidity to increase soil fertility and enhance crop productivity. Topsoil organic matter content for this region generally varies between 0.75-1.5 percent. Due to cold climatic conditions, the mineralization rate of organic matter is low and, hence, the supply of mineral nutrients to crops from soil organic matter is limited. The combination of sandy soil texture and low organic matter also restrict the nutrient holding capacity of soil. Therefore, crop and soil management practices must be implemented to ensure a sufficient supply of essential nutrients when considering growing requirements.
