Wood Ash: An Alternative Liming Material for Agricultural Soilswood ash also contains many of the nutrients originally absorbed from the soil by tree growth, so it may improve crop growth through improved nutrition. By comparison, agricultural lime contains only minimal amounts of plant nutrients. A significant amount of phosphorus, calcium, magnesium and potassium (potash) is added to the soil when wood ash is used as a liming material. Most agricultural soils are deficient in phosphorus, and it is likely that improved crop growth after liming ...

Regarding the environmental impact of fly ash stabilisation, no significant differences between fly- ash stabilised and reference road sections in the ...

Influence of wood ash on soil chemical composition and ...in various branches of economy have been rather widely studied worldwide in recent years. Whole-tree harvesting intensifies the build-up of acidity in the soil that is caused by the excess uptake of cations over anions by trees (Olsson et al.,. 1996). To obtain a more sustainable utilization of biomass fuels, the ash resulting from the combustion of biofuels can be recycled back to the soil. The ecological and biological effects of wood ash recycling are one of the main and very important.
