Metla Project 3340

Nutrient dynamics and management of forested mineral soils

Duration: 2002-2008   Keywords: ash, bioenergy, biomass, fertilisation, forest yield, liming, litter, logging residues, mineralisation, nutrient cycling, nutrients, roots, weathering
Research project group: Distinct projects 1 - Structure and function of forest ecosystems

Objectives

• soil properties in upland forest soils, factors and processes affecting them, nutrient and biomass dynamics and their significance in the functioning of forest ecosystems, and nutrient budgets in different stands (site type, tree species, climate, managed/natural, disturbed/undisturbed) (sub project 1)
• effects of forest management (fast- and slow-release fertilizers, wood ash fertilization, liming, soil preparation, prescribed burning, harvesting and slash removal) on soil properties, stand nutrient status, growth and nutrient dynamics, and the maintenance of soil fertility in intensively managed stands (sub project 2).

Results

• Sub project 1: Nutrient dynamics of forested mineral soils
• Sub project 2: Management of nutrition in forested mineral soils
