[ID: 102] 1477 Flakaliden: long-term nutrient optimization for ecosystem carbon accumulation and biomass production

We determine carbon accumulation in response to 40-years tree nutrition optimization. Tree nutrition has been administrated based on annual foliar nutrient detection and corresponding fertilization treatment. Aboveground carbon accumulation is determined by standing biomass and belowground carbon accumulation is determined by both soil carbon stock and root biomass. Based on litterfall production and consecutive measurements on tree dimensions, annual net primary production is estimated.
