“…It is based on the annealing of already oven dried samples in the muffle furnace at 550°C for several hours. Thermogravimetry (TG) extends this procedure with modern thermobalances to continuously record mass losses during soil heating (Mass Losses on Ignition–MLI) ( Oudghiri et al, ; Peikert et al, ; Kristl et al, ). Together with standardization of sample preparation and new evaluation algorithms, it allows determination of organic carbon, total organic nitrogen, clay, and carbonates with high accuracy ( Siewert , ).…”

Sustainable soil management requires reliable and accurate monitoring of changes in soil organic matter (SOM). However, despite the development of improved analytical techniques during the last decades, there are still limits in the detection of small changes in soil organic carbon content and SOM composition. This study focused on the detection of such changes under laboratory conditions by adding different organic amendments to soils. The model experiments consisted of artificially mixing soil samples from non‐fertilized plots of three German long‐term agricultural experiments in Bad Lauchstädt (silty loam), Grossbeeren (silty sand), and Müncheberg (loamy sand) with straw, farmyard manure, sheep faeces, and charcoal in quantities from 3 to 180 t ha−1 each. In these mixtures we determined the organic carbon contents by elemental analysis and by thermal mass losses (TML) determined by thermogravimetry. The results confirmed the higher reliability of elemental analysis compared to TML for organic carbon content determination. The sensitivity of both methods was not sufficient to detect the changes in organic carbon content caused by small quantities of organic amendments (3 t ha−1 or 0.1–0.4 g C kg−1 soil). In the case of elemental analysis, the detectability of changes in carbon content increased with quantities of added amendments, but the method could not distinguish different types of organic amendments. On the contrary, the based on analysis of degradation temperatures, the TML allowed this discrimination together with their quantitative analysis. For example, added charcoal was not visible in TML from 320 to 330°C, which is used for carbon content determination. However, increasing quantities of charcoal were reflected in a higher TML around 520°C. Furthermore, differences between measured (with TML110–550) and predicted mass loss on ignition using both organic carbon (with TML330) and clay contents (with TML140) were confirmed as a suitable indicator for detection of organic amendments in different types of soils. We conclude that thermogravimetry enables the sensitive detection of organic fertilizers and organic amendments in soils under arable land use.

“…56 Os espectros do DRIFT para a MO HF são similares aos espectros de matéria orgânica em sedimentos costeiros reportados na literatura. 2,10,11,16 A razão C/N sugere que a composição molecular da MO HF é derivada da mistura de materiais provenientes de fontes terrestre e marinha. A realização da contraprova determinou que as bandas de absorção presentes na faixa do 3600-1360 cm -1 são provenientes das ligações de grupos funcionais orgânicos, uma vez que estes desapareceram após a remoção da MO com H 2 O 2 .…”

“…O melhor caminho para avaliar as condições ambientais de um ecossistema costeiro é através da análise dos seus sedimentos, uma vez que os poluentes tendem a se associar às partículas finas deste compartimento geoquímico. 1,2 A matéria orgânica (MO), por afinidade química com oligoelementos e poluentes orgânicos, tende a se concentrar nas frações de argila e silte do sedimento. 3 Portanto, o conhecimento sobre a composição química dos sedimentos é de grande relevância pela possibilidade de determinar a proveniência, a distribuição, a extensão, e também os possíveis riscos de contaminação.…”

Spectroscopic techniques are powerful tools for molecular organic matter assessment in sediments, which analysis request low sample mass and are cheap, fast and easy to obtain. The aim of this work was to evaluate the elemental (C, N) and molecular composition of the organic matter in relation to the grain-size distribution over surface sediments from Sepetiba Bay. Spatial distribution of grain-size was remarkable heterogeneous, with the internal area presenting the highest levels of fine sediments, organic carbon (0.20-3.45%) and total nitrogen (
