“…The second and third year needles from the low fertility soil showed lower N, P and Mg concentrations and higher concentrations of cell wall constituents (ADF, lignin, cellulose, sugars and PPD). These results were consistent with trends found by other authors who reported that tree species on soils of low inherent fertility generally tend to produce low foliar nitrogen concentrations, high concentrations of polyphenol and greater lignification of leaf tissues (Davies et al 1964, Sanger et al 1996, Tresender and Vitousek 2001and Hattenschweiler et al 2003. This trend may be indicative of nutrient stress, which can elicit lignification in plant tissues (Stafford and Ibrahim 1992).…”

“…The concentrations of PPDs were determined using a Shimadzu GC 14-A capillary GC, with a BP5 25m × 0.25 mm i.d. column with standards of p-hydroxyl (p-hydroxybenzaldehyde, p-hydroxybenzoic acid, p-hydroxyacetophenone), vanillyl (vanillin, acetovanillone, vanillic acid), syringyl (syringaldehyde, acetosyringone, syringic acid), coumaric acid and ferulic acid (Sanger et al 1996).…”

“…It is clear from fertiliser experiments for coniferous trees that the chemical quality of needles can be altered significantly in a single species by increasing nutrient availability (Tamm 1991, Berg andTamm 1991a,b), though mineral element concentrations, rather than plant structural compounds, has been the main variable in litter affected by these treatments. Under natural soil conditions, Sanger et al (1996Sanger et al ( , 1998 showed for Scots pine that, N, lignin, cellulose as well as the chemical characteristics of the lignin polymer and hemicellulose varied significantly either between needles (second year class) and litters or between different soil types in relation to high and low base status.…”

First, second and third year needles were collected from the same branches of young Scots pine trees growing on soils of two different status (high and low fertility sites) that varied in mineral nutrient concentrations and N mineralisation potential. All needle age classes were analysed for total carbon, acid detergent fibre (ADF), lignin, cellulose, phenylpropanoid derivatives (PPD) of lignin, sugar constituents of non-crystalline, hydrated cellulose and hemicellulose, and nutrient concentrations (N, P, K, Ca, Mg and Mn). Significant intra-specific variation in the litter quality variables in relation to soils of high and low fertility was found in the second and third year needles, whereas there were no differences in the other cell wall constituents and mineral elements of the first year needles. The second and third year needles from the low fertility soil contained higher concentrations of ADF, lignin, cellulose, sugar constituents of non-crystalline, hydrated cellulose and hemicellulose, and phenylpropanoid derivatives (PPD) of lignin, but lower concentrations of N, P and Mg than the same needles from the high fertility and fertilised soils. The results in the present study indicate that under different soil fertilities, needle age classes show significant variations in the cell wall constituents and mineral elements, and suggest that this can result in significant variation in litter quality and decomposition rates.

Accumulation and composition of total organic carbon in reclaimed coal mine lands

et al. 2008

View full text Add to dashboard Cite

Reclaimed coal mine lands have the potential to sequester atmospheric carbon (C); however, limited information exists for the western USA coalfields. This study was carried out on two chronosequences (BA-C 3 grasses and DJ-shrubs) of reclaimed sites at two surface coal mines to determine the effects of vegetation, soil texture, and lignin content on soil total organic carbon (TOC) accumulations. In the BA chronosequence, TOC increased over 26 years at an average rate of 0Á52 Mg C ha À1 yr À1 in the 0-30 cm depth and was significantly correlated with clay content. Comparison between < 1 and 16-year-old stockpile soils indicated TOC content did not differ significantly. In the DJ chronosequence, TOC content in the 0-30 cm depth declined from 31Á3 Mg ha À1 in 5-year-old soils to 23Á4 Mg ha À1 in 16-year-old soils. The C:N ratios suggested that some (up to 2Á0 per cent) of the TOC was potentially derived from coal particles in these reclaimed soils. Soil total N (TN) contents followed a similar trend as TOC with TOC and TN concentrations strongly correlated. Lignin contents in TOC of all reclaimed soils and topsoil stockpiles (TSs) were higher than that of nearby undisturbed soils, indicating the recalcitrant nature of TOC in reclaimed soils and/or possibly the slow recovery of lignin degrading organism. Results indicated that TOC accumulations in DJ were largely controlled by its composition, particular lignin content. In BA sites TOC accumulation was strongly influenced by both clay and lignin contents.
