“…The results may thus possibly be affected by seasonal variations in environmental Cd concentration (cf. Lodenius, 2002;Lodenius et al, 2002). Insects were collected both passively with pitfall traps and manually.…”

Ash fertilization of forests returns nutrients to forest ecosystems and has a positive effect on soil pH, but it also may elevate Cd concentrations of forest biota. Cadmium concentrations of some forest insects (Formica ants, carabids and Coleopteran larvae from decaying wood) were investigated in southern Finland, where two plots were fertilized with wood ash, while two other plots represented unfertilized control plots. In ants, mean Cd concentration was 3.6 ± 1.4 mg/kg, with nest workers having significantly higher concentrations than workers trapped in pitfall traps. Concentrations at fertilized and unfertilized plots were similar. In carabid beetles, the average Cd concentration of Carabus glabratus was 0.44 ± 0.36 mg/kg, with no significant difference between control plots and fertilized plots. In another carabid beetle, Pterostichus niger, mean Cd concentration was higher at fertilized plots compared to control plots. We conclude that the variation of Cd concentrations in the insects studied is more efficiently controlled by species-specific differences than fertilization history of the forest floor.

“…The use of wood ash as a fertilizer in forestry has often been regarded as a practical and cheap solution to the waste and treatment problem of ash. However, the high concentrations of Cd set limits on the amount of ash that can be applied and on the frequency with which it is used (Lodenius et al, 2002). The toxicity of Cd is mainly related to its bioavailability, not to its``total'' concentration.…”

“…Many of the environmental concerns related to ash recycling, e.g., heavy metal accumulation in berries and mushrooms (Moilanen et al 2006), accumulation of environmental pollutants in soil fauna (Lundkvist 1998) or forest fauna (Lodenius et al 2002), potentially harmful impacts of ash on soil microbial community (Perkiömäki 2004), heavy metal leaching to water bodies (Piirainen and Domisch 2004), have not been proven to be so serious that it would be impossible to fertilize the forest sites at least once during a tree stand generation.…”

Fertilization of drained peatland forests with wood ash and different commercial phosphorus fertilizers (calcium phosphates) generally give similar stand growth responses. However, it has been shown that use of calcium phosphate fertilizers generally lead to highly increased P release to recipient water courses. On the other hand, no corresponding release has been reported after ash fertilization. Soil samples from the surface peats from a nutrient poor and a fertile drained peatland site were collected before and 1-4 years after application of five different types of ash products. The changes over time in the different chemical forms of P in the substrate were studied. The results indicated that the reason for the low liability to leaching of ash fertilizers was that significant amounts of P are adsorbed by Al and Fe during weathering of the ash fertilizers. However, further studies are needed to clarify whether the adsorption of P occurs with the Al and Fe of the ash or the native Al and Fe compounds present in soil before ash fertilization.
