Effect of volcanic ash on GHG production rates and soil properties in a drained peat soil compared to wood ash

Effects of Wood Ash Fertilization on Forest Soil Chemical Properties

The effects of wood ash fertilization on soil chemical properties were studied in three young Scots pine (Pinus sylvestris L.) plantations and a Norway spruce (Picea abies (L.) Karst.) plantation with different site fertility in southern Finland. The dose of 3 t ha–1 of loose wood ash was applied to 4 replicate plots (25 × 25 m) at each experiment. Humus layer and mineral soil samples were take...

the effect of granulated wood-ash fertilization on soil properties and greenhouse gas (GhG) emissions in boreal peatland forests

The amount of wood ash produced in power plants is increasing with increasing use of forest biomass in energy production. Wood ash can be recycled as fertilizer especially in boreal peatland forests naturally rich in nitrogen. Improved nutrient availability and increases in soil pH can enhance microbial activities, decomposition of organic matter and greenhouse gas (GHG) emissions. We studied t...

The Effect of Volcanic Ash Incorporation, Slope and Vegetation on Soil Surface Runoff and Erodibility Characteristics

Hygroscopic Properties of Volcanic Ash

Limited observational data exists on the physical interactions between volcanic ash particles and water vapor; yet it is thought that these interactions can strongly impact the microphysical evolution of ash, with implications for its atmospheric lifetime and transport, as well as formation of water and ice clouds. In this study, we investigate for the first time, the hygroscopic properties of ...

Effect of aggregate structure on VOC gas adsorption onto volcanic ash soil.

The understanding of the gaseous adsorption process and the parameters of volatile organic compounds such as organic solvents or fuels onto soils is very important in the analysis of the transport or fate of these chemicals in soils. Batch adsorption experiments with six different treatments were conducted to determine the adsorption of isohexane, a gaseous aliphatic, onto volcanic ash soil (Ta...
