“…The high P content of bank material found in this study (718 mg P kg −1 ) may be derived from different sources related to agricultural activities (fertilization), inflow of reduced groundwater, maintenance processes in the stream channel (weed cutting and dredging), and inflow of stream water through the hyporheic zone. Active mining of P in the buffer strip through phytoremediation can therefore be a very important maintenance activity (Adler et al, 2008).…”

Phosphorus loss from bank erosion was studied in the catchment of River Odense, a lowland Danish river basin, with the aim of testing the hypothesis of whether stream banks act as major diff use phosphorus (P) sources at catchment scale. Furthermore, the study aimed at analyzing the impact of diff erent factors infl uencing bank erosion and P loss such as stream order, anthropogenic disturbances, width of uncultivated buff er strips, and the vegetation of buff er strips. A random stratifi ed procedure in geographical information system (GIS) was used to select two replicate stream reaches covering diff erent stream orders, channelized vs. naturally meandering channels, width of uncultivated buff er strips (≤2 m and ≥10 m), and buff er strips with diff erent vegetation types. Th irty-six 100-m stream reaches with 180 bank plots and a total of 3000 erosion pins were established in autumn 2006, and readings were conducted during a 3-yr period (2006)(2007)(2008)(2009). Th e results show that neither stream size nor stream disturbance measured as channelization of channel or the width of uncultivated buff er strip had any signifi cant (p < 0.05) infl uence on bank erosion and P losses during each of the 3 yr studied. In buff er strips with natural trees bank erosion was signifi cantly (p < 0.05) lower than in buff er strips dominated by grass and herbs. Gross and net P input from bank erosion amounted to 13.8 to 16.5 and 2.4 to 6.3 t P, respectively, in the River Odense catchment during the three study years. Th e net P input from bank erosion equaled 17 to 29% of the annual total P export and 21 to 62% of the annual export of P from diff use sources from the River Odense catchment. Most of the exported total P was found to be bioavailable (71.7%) based on a P speciation of monthly suspended sediment samples collected at the outlet of the river basin. Th e results found in this study have a great importance for managers working with P mitigation and modeling at catchment scale. Phosphorus Load to Surface Water from Bank Erosion in a Danish Lowland River BasinBrian Kronvang,* Joachim Audet, Annette Baattrup-Pedersen, Henning S. Jensen, and Søren E. Larsen Q uantification of phosphorus (P) sources to surface waters at catchment scale involves a range of both point and diff use emissions (Sharpley and Rekolainen, 1997;Heathwaite et al., 2005;Kronvang et al., 2007). In many developed countries around the world, diff use P losses are today the dominant source in P budgets at river basin or catchment scale (Kronvang et al., 2007;Maguire et al., 2009). River basin managers need to establish knowledge of major diff use P sources to cost-eff ectively combat the eutrophication problem in surface waters (Haygarth et al., 2009). Phosphorus models are one of the methods used by river basin managers to quantify the magnitude of diff erent P pathways (Schoumans et al., 2009). Stream bank erosion is, however, seldom included in these models even though recent investigations have suggested bank erosion to be an important P source (Ha...

“…Over 20% of Zn can be removed from the soil within a year with the biomass produced. Adler et al (2008) who conducted phytoremediation studies on several woody and herbaceous perennials species found that trees need longer time to establish (to produce large biomass) but have higher nutrient uptake and use efficiency.…”

Heavy metals are very toxic and soil contaminated with sewage sludge urgently need remediation in order to avoid related health hazards. Phytoremediation is a low cost and reliable technique to remediate heavy metal contamination. However phytoremediation using timber species was rarely reported and its efficiency was questionable. A field study was conducted to examine the efficiency of two timber species namely Acacia mangium and Melaleuca cajuputi in phytoextraction of Zn, Cu and Cd from contaminated soil. Two hundred of A. mangium and M. cajuputi were planted on sewage sludge disposal site and the growth was recorded for 12 months before at the end total biomass of each species was determined. Results show in 12 months, about 72 and 4 t ha −1 of aboveground biomass can be produced by A. mangium and M. cajuputi, respectively. Both species show potential for phytoremediation, however A. mangium is more efficient compared to M. cajuputi where efficiency of A. mangium to remove Zn was 24.4, 6.2 for Cu and 9.5% for Cd. As for M. cajuputi the efficiency was 1.3, 0.3 and 0.14% for Zn, Cu and Cd, respectively. It is projected that A. mangium require 5, 17 and 20 years to remove 79.82 kg ha −1 of Zn, 46.94 kg ha −1 of Cu and 2.33 kg ha −1 of Cd, respectively.

“…Coppicing reinvigorates growth and an improved coppicing response would be beneficial for improving productivity of SRC systems (Kauppi et al, 1988). Stems in coppiced stands also have higher bark proportions compared with single stem systems as the bark is roughly proportional to the area: volume ratio of the stem (Adler et al, 2008). This has relevance for the use of wood chip in thermal conversion technologies where Figure 3 Testing allelic variation in SxMAX alleles through transformation rescue of their cognate Arabidopsis max mutant.…”

Willows (Salix spp.) are important biomass crops due to their ability to grow rapidly with low fertilizer inputs and ease of cultivation in short-rotation coppice cycles. They are relatively undomesticated and highly diverse, but functional testing to identify useful allelic variation is time-consuming in trees and transformation is not yet possible in willow. Arabidopsis is heralded as a model plant from which knowledge can be transferred to advance the improvement of less tractable species. Here, knowledge and methodologies from Arabidopsis were successfully used to identify a gene influencing stem number in coppiced willows, a complex trait of key biological and industrial relevance. The strigolactone-related More AXillary growth (MAX) genes were considered candidates due to their role in shoot branching. We previously demonstrated that willow and Arabidopsis show similar response to strigolactone and that transformation rescue of Arabidopsis max mutants with willow genes could be used to detect allelic differences. Here, this approach was used to screen 45 SxMAX1, SxMAX2, SxMAX3 and SxMAX4 alleles cloned from 15 parents of 11 mapping populations varying in shoot-branching traits. Single-nucleotide polymorphism (SNP) frequencies were locus dependent, ranging from 29.2 to 74.3 polymorphic sites per kb. SxMAX alleles were 98%–99% conserved at the amino acid level, but different protein products varying in their ability to rescue Arabidopsis max mutants were identified. One poor rescuing allele, SxMAX4D, segregated in a willow mapping population where its presence was associated with increased shoot resprouting after coppicing and colocated with a QTL for this trait.
