“…cycling was reported by Goulding and Stevens (1988), Fahey et al (1991), and by Proe et al (1999) for the Kielder site. According to Proe et al (1999), mineralization of logging residues does not make K ? easily available for tree uptake as it is leached immediately to deeper horizons or lost in ground and surface waters.…”

“…Nutrient leaching from the litter layer after clearfelling of the first rotation Sitka spruce stands have been evaluated in the past (Malcolm and Titus 1983), and the nutrient changes in the peaty gley soils after the clearfelling of the Sitka spruce stands also assessed (Titus and Malcolm 1991). Growth reductions in Sitka spruce after 10 years following whole tree harvesting at these sites were reported by Proe and Dutch (1994) and tree nutrient status through foliar analysis was reported by Proe et al (1996Proe et al ( , 1999.…”

The practice of harvesting forest residues is rapidly increasing due to rising demand for renewable energy. However, major concerns have been raised about the sustainability of this practice and its net impact on long term soil ability to support forest productivity, particularly through second and subsequent rotations. In this study, soil chemical properties such as acidity, total N and C, available NO 3 -N and NH 4 -N and exchangeable cations were measured in all horizons in peaty gleys soils under one of the oldest experiments in Europe-a 28-year-old second rotation stand of Sitka spruce (Picea sitchensis), in Kielder forest, UK. Treatments included Whole Tree Harvesting (WTH-of all above ground biomass), Conventional stem-only harvesting (CH) of the first rotation crop, and repeated Fertilisation (FE) after the planting of the second rotation forest. This study demonstrates the soil changes underpinning the reduced second rotation tree productivity on these acidic upland sites under WTH, a further 18 years after the investigation by Proe and Dutch (1994). Overall, WTH increased soil acidity significantly (p \ 0.05) and reduced soil base saturation whilst FE reduced soil acidity (p \ 0.05) and increased soil base saturation as compared to CH. Soil moisture was significantly higher (p \ 0.01) under WTH compared to CH and FE plots. There was no evidence that WTH decreased soil organic carbon (SOC) and soil nitrogen (N), but to the contrary there were significantly (p \ 0.01) higher concentrations and stocks of total C and N in the WTH soils compared with CH and FE. The depletion of SOC and N in CH and FE plots was attributed to much higher soil mineralisation rates associated with the brash and fertilisation as compared to the WTH plots, where significantly less soil available NO 3 -N (p \ 0.01) was found. In the long term WTH on peaty gley soils appears positive for soil C and N storage. However, WTH had a long term negative impact on soil and tree nutrition of K ? and P, which are currently at deficient levels, but has had a stabilising effect on tree N nutrition as measured in twigs and needles. These results suggest that whilst WTH lead to a reduction in aboveground tree biomass compared to conventional harvest, these practices on selected soil types and certain sites may be beneficial for soil C and N sequestration. The overall findings of this study imply that cost benefit analyses for each site should be carried out before decisions are made on the appropriate type of forest operations (harvesting and replanting), considering both geology and soils in order to serve both environmental benefits, long term sustainability and the available biomass production for timber and biofuel.

“…The foliar P concentrations in all treatments at age 10 years, however, were below the critical concentration of 0.093-0.11% suggested for slash pine (Xu et al, 1995a). The P:N ratio was also below the recommended ratio of 10% or more for most tree species (Proe et al, 1999). Foliar N concentration was marginal when compared to the recommended critical concentration of 0.90% for slash pine (Xu et al, 1995a).…”

“…Except for P and N concentrations, foliar nutrient concentrations were above critical levels (K = 0.30%; Mg = 0.07%; and Ca = 0.12%) reported for the slash and Caribbean pines, the parent taxa of the F1 hybrid (Simpson and Osborne, 1993;Xu et al, 1995c). The element to N ratios (Table 2) were also above suggested critical levels for most tree species: K:N = 29-35%; Ca:N = 2.5% and Mg:N = 4% (Proe et al, 1999;Olsson et al, 2000;Moilanen et al, 2005). The foliar P concentrations in all treatments at age 10 years, however, were below the critical concentration of 0.093-0.11% suggested for slash pine (Xu et al, 1995a).…”

“…Although the effect of harvest residues is not always observed (Olsson et al, 1996;Knoepp and Swank, 1997), studies on pines (Proe and Dutch, 1994;Smith et al, 2000;Simpson et al, 2003;Tiarks et al, 2003) and eucalypts (Jones et al, 1999;Nzila et al, 2002;Mendham et al, 2003) have shown significant growth responses as a result of residue retention. A number of these studies have clearly demonstrated the direct linkage of tree growth to the nutrition effect of harvest residues (Proe et al, 1999;Nzila et al, 2002;Mendham et al, 2003;Blumfield et al, 2004).…”
