This literature-based project was initiated to assess the environmental effects of silvicultural applications of fertilization in forest stand tending.
The assessment entailed the assembly, review and synthesis of published and unpublished literature on forest fertilization related to environmental effects on soils, vegetation, water quality, fish and aquatic communities, and wildlife. The current state of knowledge was assessed for its adequacy in addressing scientific issues and public concerns related to forest fertilization. Models were created to link cause and effect of forest fertilization application on soils, vegetation, water quality, fish and aquatic communities, and wildlife. The models aided in the review process and simplified the reporting of findings. The literature review focused on nitrogen-based (ie. urea and ammonium nitrate) fertilizers.
Research findings and conclusions were presented, summarizing to what extent forest fertilization alters soils, vegetation, water quality, fish and aquatic communities, and wildlife.
