“…The Actinobacteria can also contribute to tree vitality by antifungal activity against some soil-borne pathogens (Kamara, Gangwa 2015). The differences in fungal species abundance between both types of fertilized sites and control are consistent with previous studies that showed species-specific changes in the ECM fungal community composition after forest liming (Jonsson et al 1999;Kjøller, Clemmensen 2009). Our data indicated a strong effect of wood ash application on the ECM species abundance, which is in accordance with previous studies (Klavina et al 2015b).…”

ABSTRACT:We compared the effects of forest fertilization with wood ash and potassium (K) sulphate on growth and mycorrhizal colonization of fine roots and on other soil microorganisms in Norway spruce (Picea abies) stands with symptoms of foliage damage. Fertilization trials with the application of 0.25 kg·m -2 of wood ash and similar amount of K as K sulphate were established. One year later, a total of 270 soil samples with roots were collected to determine morphological parameters of fine roots and extent of mycorrhization. Soil samples were collected to characterize soil chemical composition and number of colony forming units (CFU) of soil bacteria and fungi. The results showed that fine root biomass, length and volume, and relative abundance of living root tips were significantly higher in control sample plots than in treated plots. Abundance of bacterial CFU was higher in both wood ash and K sulphate treatments than in control plots; the Actinobacteria were more common in plots fertilized with wood ash than in other treatments. Relative abundance of several fungal species in sites fertilized with wood ash differed significantly from control sites and from sites fertilized with K sulphate.

“…Wood ash is a common liming material as it increases forest soil capacity to neutralize acids (Kjøller and Clemmensen 2009). Similar to effect of liming, wood ash application leads to changes in tree root distribution (Majdi and Viebke 2004) and increase of fine root biomass (Nowotny et al 1998;Jonsson et al 1999).…”

“…The greatest adverse ecological effect of wood ash fertilization has been reported for acidophilic ecosystems, particularly on bryophyte, soil bacteria and ECM fungal communities (Pitman 2006;Augusto et al 2008). In general, differences in ECM fungal community composition have been observed after lime application (Andersson and Söderström 1995;Erland and Taylor 2002;Kjøller and Clemmensen 2009). ECM fungal mycelium was shown to grow slower in limed peat substrate with increased pH than in unlimed peat (Erland et al 1990).…”

We studied long-term effects of fertilization with wood ash on biomass, vitality and mycorrhizal colonization of fine roots in three conifer forest stands growing in Vacciniosa turf. mel. (V), Myrtillosa turf. mel. (M) and Myrtillosa turf. mel./Caricoso-phragmitosa (MC) forest types on peat soils. Fertilization trials amounting 5 kg/m(2) of wood ash were established 12 years prior to this study. A total of 63 soil samples with roots were collected and analysed. Ectomycorrhizal (ECM) fungi in roots were identified by morphotyping and sequencing of the fungal internal transcribed spacer (ITS) region. In all forest types, fine root biomass was higher in fertilized plots than in control plots. In M forest type, proportion of living fine roots was greater in fertilized plots than in control plots, while in V and MC, the result was opposite. Fifty ECM species were identified, of which eight were common to both fertilized and control plots. Species richness and Shannon diversity index were generally higher in fertilized plots than in control plots. The most common species in fertilized plots were Amphinema byssoides (17.8%) and Tuber cf. anniae (12.2%), while in control plots, it was Tylospora asterophora (18.5%) and Lactarius tabidus (20.3%). Our results showed that forest fertilization with wood ash has long-lasting effect on diversity and composition of ECM fungal communities.

“…Indeed, we have discovered many of the important factors that govern community structure from studies of specific communities. For example, we now know that the structure of ectomycorrhizal fungal communities is affected by various ecological factors and management practices including soil type (Gehring et al 1998), fire (Grogan et al 2000;Chen and Cairney 2002;Anderson et al 2007), herbivory (Gehring and Bennett 2009), canopy gap formation (Grebenc et al 2009), soil fertility (Kranabetter et al 2009), liming (Kjøller and Clemmensen 2009;Rineau et al 2010), heavy metal pollution (Markkola et al 2002), land use history (Diedhiou et al 2010) and urbanization (Baxter et al 1999). It stands to reason that the structure of a community is altered by such factors and practices because the component species respond in different ways to them.…”
