Journal ArticleDOI
The effect of fire on soil organic matter--a review.
TL;DR: In this article, the effect of forest fires on the quantity and quality of organic matter (OM) in soil has been investigated and the most stable pool of soil organic carbon has been found to be composed of free lipids, colloidal fractions, including humic acids and fulvic acids.
Journal ArticleDOI
How does fire affect the nature and stability of soil organic nitrogen and carbon? A review
TL;DR: In this paper, the authors suggest a concept in which char is a heterogeneous mixture of heat-altered biopolymers with domains of relatively small polyaromatic clusters, but considerable substitution with N, O and S functional groups.
Journal ArticleDOI
Improvement of 13C and 15N CPMAS NMR spectra of bulk soils, particle size fractions and organic material by treatment with 10% hydrofluoric acid
TL;DR: In this article, the effect of treatment with 10% hydrofluoric acid on bulk chemical composition and resolution of solid-state 13C NMR spectra was investigated with six soils, some associated particle size fractions, plant litter and compost.
Journal ArticleDOI
N-15 and C-13 CPMAS and solution NMR studies of N-15 enriched plant material during 600 days of microbial degradation
TL;DR: In this article, Nitrogen-15 enriched plants ( Lolium perenne (rye grass) and Triticum sativum (wheat) have been composted under controlled conditions up to 630 days.
Journal ArticleDOI
Soil C and N stocks as affected by cropping systems and nitrogen fertilisation in a southern Brazil Acrisol managed under no-tillage for 17 years
Jeferson Diekow,João Mielniczuk,Heike Knicker,Cimélio Bayer,Deborah Pinheiro Dick,Ingrid Kögel-Knabner +5 more
TL;DR: The remarkable potential of legume cover crops and N fertilisation under no-tillage to improve SOM stocks and thus, soil and environmental quality in humid subtropical regions is indicated.
