In the face of global climate change there is an increasing demand for biofuel, which exerts pressure on production and thus management of biofuel plantations. The intensification of whole-tree harvest from biofuel plantations increases export of nutrients. Returning ash from biofuel combustion to the forest plantations can amend the soil nutrient status and thus facilitate sustainable forest management. However, ash affects the forest floor decomposer food web, potentially changing organic… Expand

The complexity of wood ash fertilization disentangled: Effects on soil pH, nutrient status, plant growth and cadmium accumulation
Abstract Wood ash is a by-product from energy production that can be recycled to forests to regain nutrients and prevent acidification. However, low concentrations of nitrogen (N) in wood ash mayExpand
Biomass ash formulations as sustainable improvers for mining soil health recovery: Linking soil properties and ecotoxicity.
Evidence is provided that ash stabilization, formulation and supplementation with organic matter could be sustainable strategies to restore highly degraded mining soils and to recover their ecological functions and the importance of analyzing combined effects on soil physico-chemical properties and ecological function recovery to assess restoration strategy efficiencies in complex multi-stressor environments.

The relative importance of the bacterial pathway and soil inorganic nitrogen increase across an extreme wood‐ash application gradient
Ash from combustion of biofuels, for example wood chips, is often deposited as waste, but due to its high content of essential plant nutrients and alkalinity, it has been proposed to recycle ash as aExpand
Ash application enhances decomposition of recalcitrant organic matter
Abstract Harvesting whole-tree biomass for biofuel combustion intensifies removal of nutrients from the ecosystem. This can be partly abated by applying ash from the combustion back to the system, asExpand
Wood ash application in a managed Norway spruce plantation did not affect ectomycorrhizal diversity or N retention capacity
It is demonstrated that applying up to 6 t ha−1 of wood ash in this type of plantation forest is a safe management practice that does not increase N leaching or negatively affect ECM fungi. Expand
Wood ash application increases pH but does not harm the soil mesofauna.
It is concluded that short-term chronic effects of wood ash differ among different soil types, and osmotic stress is the likely cause of effects while high pH and heavy metals is of minor importance. Expand
Micro vertical changes in soil pH and base cations over time after application of wood ash on forest soil
Abstract Application of wood ash to forest soils is used to counteract acidification and to reintroduce nutrients otherwise lost by harvesting, particularly in silvicultural systems with intensifiedExpand
Changes of Chemical and Biological Properties of Distinct Forest Floor Layers after Wood Ash Application in a Norway Spruce Stand
WA application in autumn lead to a significant increase in pH, base cation concentration, and distinct losses in C and N content in the OL layer in the first month; however, at the beginning of the vegetation period, the most pronounced effect of WA was observed in OF and especially OH horizons; no changes were found in the A-horizon.

Changes in SOM composition and stability to microbial degradation over time in response to wood chip ash fertilisation
Abstract Recirculation of nutrients from wood chip combustion by ash fertilisation of forest systems can be used to re-introduce nutrients that are otherwise lost, counteracting nutrient depletionExpand
Effects of ash application on nutrient and heavy metal fluxes in the soil and soil solution in a Norway spruce plantation in Denmark
Abstract Wood ash application is used in forests to counteract nutrient losses and acidification due to intensified harvesting methods, where harvest residues are removed. The aim of the study was toExpand
The effects of fertiliser or wood ash on nitrate reductase activity in Norway spruce fine roots
Abstract In a field experiment, lasting two years, an intensive monitoring of the nitrate reductase activity (NRA) of Norway spruce fine roots was used to investigate the question of whether the NRAExpand
Wood Ash Induced pH Changes Strongly Affect Soil Bacterial Numbers and Community Composition
All of the observed bacterial responses can be directly explained by the wood ash induced changes in pH, electrical conductivity and the addition of wood ash inherent nutrients. Expand
