• Short term impact of application of different doses of wood ash on greenhouse gas (GHG) emissions from peat (2022) · doi

  It is well studied that application of wood ash improves forest growth in peatlands and significantly increases biomass production in the forest floor; however, there is limited knowledge on the shortterm impact on the soil GHG (CO2, N2O, CH4) fluxes after application of wood ash, specifically, if different doses of the wood ash are applied.

• Impact of coal ash and phosphogypsum application on soil fertility of Chernozem soils of North Kazakhstan (2017) · doi

  The coal ash and phosphogypsum usage as soil fertilizers is appropriate, however, there is a need for additional investigation of ecological risks related with this industrial waste utilization technology.
