“…Our results suggest that smaller FWD and highly decayed CWD can represent important sources of nutrients for these intensively managed ecosystems. Although less studied, micronutrients are necessary for tree physiological health and nutrition (Boardman and McGuire 1990;Stone 1990;Hagen-Thorn and Stjernquist 2005;Pallardy 2008) and, based on observations from this study, significant quantities of highly decayed woody debris could represent an important pool of these elements. Given the high nutrient concentrations in FWD observed in our study and rapid decomposition rates of this material, we expect that retaining significant stocks of this material could help mitigate short term nutrient losses due directly to harvest removals or indirectly from leaching following harvest.…”

Nutrient concentrations in coarse and fine woody debris of Populus tremuloides Michx.-dominated forests, northern Minnesota, USA Klockow P.A., D'Amato A.W., Bradford J.B., Fraver S. (2014). Nutrient concentrations in coarse and fine woody debris of Populus tremuloides Michx.-dominated forests, northern Minnesota, USA. Silva Fennica vol. 48 no. 1 article id 962. 24 p. Highlights • We examine effects of size, species, and decay on woody debris nutrient concentrations. • Results indicate wide variation in nutrient concentrations across the factors examined. • Fine woody debris nutrient concentrations were greater than in coarse woody debris. • Coarse woody debris nutrient concentrations generally increased as decay progressed. • Results suggest high fine woody debris stocks can represent an important nutrient source. Abstract Contemporary forest harvesting practices, specifically harvesting woody biomass as a source of bioenergy feedstock, may remove more woody debris from a site than conventional harvesting. Woody debris, particularly smaller diameter woody debris, plays a key role in maintaining ecosystem nutrient stores following disturbance. Understanding nutrient concentrations within woody debris is necessary for assessing the long-term nutrient balance consequences of altered woody debris retention, particularly in forests slated for use as bioenergy feedstocks. Nutrient concentrations in downed woody debris of various sizes, decay classes, and species were characterized within one such forest type, Populus tremuloides Michx.-dominated forests of northern Minnesota, USA. Nutrient concentrations differed significantly between size and decay classes and generally increased as decay progressed. Fine woody debris (≤ 7.5 cm diameter) had higher nutrient concentrations than coarse woody debris (> 7.5 cm diameter) for all nutrients examined except Na and Mn, and nutrient concentrations varied among species. Concentrations of N, Mn, Al, Fe, and Zn in coarse woody debris increased between one and three orders of magnitude, while K decreased by an order of magnitude with progressing decay. The variations in nutrient concentrations observed here underscore the complexity of woody debris nutrient stores in for-ested ecosystems and suggest that retaining fine woody debris at harvest may provide a potentially important source of nutrients following intensive removals of bioenergy feedstocks.

Boron Fertilization Enhances the Induced Defense of Silver Birch

et al. 2011

Boron (B) deficiency is a common micronutrient deficiency that has been reported to affect the phenolic metabolism of plants. Thus, it may play a role in defense against herbivorous animals. However, the role of B in a plant's resistance to herbivores has not received any particular attention from researchers. In this study, we tested the effects of B nutrition 1) on the biochemical and mechanical defenses of birches and the growth of seedlings, and 2) the resistance of seedlings to larvae of the autumnal moth, Epirrita autumnata. Boron fertilization improved the resistance of birch, which was shown as reduced pupal weight of the herbivore. However, B fertilized trees suffered from heavier defoliation than unfertilized ones due to compensation feeding of larvae. The growth of the seedlings was diminished, and several biochemical changes occurred in leaves of herbivore seedlings, and B also played a role in these changes. Polyphenoloxidases (PPOs) and peroxidases (PODs) and their substrates, chlorogenic acids, were induced by herbivory in B fertilized seedlings but not in unfertilized seedlings. The lower pupal weights and increased consumption of the herbivores were probably linked to the plants' phenoloxidase-mediated production of reactive quinones, which decrease the nutritive value. Herbivory upon new stems led to an increase in the number of resin glands that provide defense against mammalian herbivores. Herbivory also had a substantially negative effect on B concentration in leaves of B fertilized seedlings. We postulate that B nutrition of trees may play a significant role in the induced defense of birches.

“…Hagen- Thorn and Stjernquist (2005) also reported that the Mn concentration in ash leaves were only 5-10% of the levels of other species at the same site. Because Hagen- Thorn and Stjernquist (2005) compared the VAM-mycorrhiza species ash with the ectomycorrhiza species beech, birch, lime, oak, and spruce, that disparity seemed to be involved in the diVerent Mn uptake behaviour. Microbiological activity in the rhizophere plays an important role for Mn oxidation and reduction processes that inXuence the Mn availability to plants.…”

“…In contrast, the Mn concentrations in the roots correspond approximately for both species on the same soils (Weber 1998). Just as Hagen- Thorn and Stjernquist (2005) stated, further investigations to clarify these Wndings are very necessary.…”

“…Microbiological activity in the rhizophere plays an important role for Mn oxidation and reduction processes that inXuence the Mn availability to plants. However, the microbiological activity itself can be inXuenced by VAM-mycorrhiza, which has a negative eVect on the number of Mn reducing bacteria in root vicinity (Marschner 1995, cited in Hagen-Thorn andStjernquist 2005). However, sycamore is also a VAMmycorrhiza species (cf.…”

Growth and nutrition of young European ash (Fraxinus excelsior L.) and sycamore maple (Acer pseudoplatanus L.) on sites with different nutrient and water statuses

This study aimed to improve knowledge about the nutritional status, site requirements and site classiWcation for European ash (Fraxinus excelsior L.) and sycamore maple (Acer pseudoplatanus L.) by reinvestigating young plantations from 1991/1992 on windfall-aVected areas in Bavaria/Germany after another decade. Compared to the Wrst survey in 1995, most stands improved their nutritional status until 2006. With the data set of element concentrations in leaves of ash and sycamore available, the range of adequate nutrition could be determined for these species in the pole stage phase. Both species show considerable height growth on a wide range of sites. Mean annual height growth of dominant sycamore trees increased with rising foliar N or P concentrations but not for Ca, Mg, K, Mn, Fe and Al. For ash, there was no relationship between the foliar nutrient level of any element and mean annual height growth. However, total height around age 20 was favourably inXuenced by high base saturation and a good water supply at well-drained sites. On acid soils, where nutrients are delivered by subsurface water Xow, well-growing stands are found as well. Soil water status according to the state forest soil classiWcation had no signiWcant impact on mean annual height growth. Ash and sycamore show reduced productivity on some (moderately) dry soils and fail on poorly drained moist sites. Based on these results, the classiWcation of forest sites suitable for ash and sycamore within the Bavarian study sites was revised.
