A comparison of soil extraction procedures for 31P NMR spectroscopy
The effect of extractants on phosphorus determination by 31 P NMR spectroscopy was examined using five forest floor samples. The extractants used were: 0.25 M NaOH, 1:6 soil to Chelex in water, 1:6Expand
Black (pyrogenic) carbon: a synthesis of current knowledge and uncertainties with special consideration of boreal regions
Abstract. The carbon (C) cycle in boreal regions is strongly influenced by fire, which converts biomass and detrital C mainly to gaseous forms (CO2 and smaller proportions of CO and CH4), and someExpand
Applications of NMR to soil organic matter analysis : History and prospects
More than 30 years have passed since the first application of nuclear magnetic resonance (NMR) spectroscopy to soil organic matter (SOM). Since then, there has been an explosion of applications usingExpand
Effects of charring on mass, organic carbon, and stable carbon isotope composition of wood
Abstract To aid in understanding black carbon (BC) formation during smoldering combustion in forest fires, we characterized charring of a softwood and hardwood. Charring (150, 340, 480 °C) causedExpand
13C nuclear magnetic resonance spectroscopy with cross-polarization and magic-angle spinning investigation of the proximate-analysis fractions used to assess litter quality in decomposition studies
NMR shows that cutin and condensed tannin are both significant components of litter and its extraction residues, in addition to lignin and carbohydrate, and Hydrolysis with H2SO4 removes carbohydrates and amino acids, leaving the KL fraction derived from cutin, tann in, and lign in. Expand
Strengthening the soil organic carbon pool by increasing contributions from recalcitrant aliphatic bio(macro)molecules
Abstract Photosynthetically fixed CO 2 is converted into terrestrial bio(macro)molecules and sequestered as soil organic matter (SOM) by (bio)chemical and physical stabilization processes. SOM isExpand
Plant traits and wood fates across the globe: rotted, burned, or consumed?
It is demonstrated how this trait-based approach to predicting wood turnover is currently limited by oversimplified treatment of dead wood pools in several leading global C models and by a lack of quantitative empirical data linking woody plant traits with the probability and rate of each turnover pathway.

Linking Chemical Reactivity and Protein Precipitation to Structural Characteristics of Foliar Tannins
The results suggest that structural characteristics of tannins play an important role in regulating their reactivity in ecological processes. Expand
How surface fire in Siberian Scots pine forests affects soil organic carbon in the forest floor: Stocks, molecular structure, and conversion to black carbon (charcoal)
[1] In boreal forests, fire is a frequent disturbance and converts soil organic carbon (OC) to more degradation-resistant aromatic carbon, i.e., black carbon (BC) which might act as a long-termExpand
