Use of soil amendments to restore productivity on poorly regenerated sites after logging in the boreal mixedwood forest
One of the major challenges in silviculture is to ensure the productivity of managed forests. Boreal forest sites are often deficient in nutrients essential for tree growth (nitrogen (N) and phosphorus (P)) and may not regenerate well after clear cutting. The aims of my research revolve around the use of fertilizing residual materials, i.e. biochar, wood ash and manure, individually and in combination, to restore or improve forest productivity of poorly regenerated sites after logging, and to help establish white spruce Picea glauca (Moench) Voss) plantations in a context of significant competition by understory vegetation. My thesis evaluates the effect of organic amendments on soil properties, tree growth, leaf nutrition, and competing vegetation using taxonomic and functional approaches.
