“…Influence of sewage sludge biochar-cattle manure compost mixtures on organic matter Loss on ignition (LOI) refers to mass loss of solid samples, due to loss of moisture content, carbon and other elements when the soil sample is heated at specific temperatures [37]. Organic matter is composed from carbon, nitrogen, oxygen and hydrogen, but the proportions of each component can vary depending on the source of the organic matter [28]. Sewage sludge and manure are similar organic wastes in terms of nitrogen (N) and carbon (C) content [38,39].…”

Organic wastes have been used in agriculture many years ago, due to its capacity to improve soil quality. The manure was used before the occurrence of chemical fertilizers and treated / untreated sewage sludge, started to be used as a fertilizer a few years ago. The aim of the study is to evaluate the organic matter, organic carbon, organic content and soil composition, after application in greenhouse conditions, of mixtures made from sewage sludge biochar and cattle manure compost. The biochar and compost used in different concentrations, at 5 t/ha and 30 t/ha, application rates, in greenhouse conditions, for a period of 90 days, improved organic matter, organic carbon and organic content from the soil used in experiment. The sewage sludge biochar and the cattle manure compost had similar effects on the parameters determined in the study. Organic and inorganic soil components, identified by the ATR-FTIR method, have not been modified by application of sewage sludge biochar and cattle manure compost.

“…3b). The major shift toward higher values within the ombrotrophic peatland unit is most likely associated with a drastic increase in the TOC, although straightforward comparison with the lacustrine sediments should be avoided without any proxy calibration from TOC, porosity and moisture measurements (Chawchai et al, 2016;Woodward and Gadd, 2018). This major shift is also accompanied by a sharp delivery decrease of detrital siliciclastic components (Ti, K, Rb, Si) at the transition between the lacustrine and ombrotrophic peatland units (Fig.…”

The introduction and application of high resolution XRF core scanners has made an enormous contribution to palaeoclimate science over the last two decades. These core scanners have become essential analytical tools for the investigation of sedimentary and other natural cumulative records of environmental change. Their widespread adoption by the environmental and geoscience communities has had a significant impact on the ability to systematically record high resolution chemical profiles in marine and lake sediments and soils. The range of applications has broadened beyond sedimentology and palaeoclimatology and now extends into scanning samples of speleothems, corals, mumiyo mounds, rocks, sedimentary nodules, archaeological artefacts, tree sections and melt segregations. Other areas exploiting the capability of XRF core scanners are mineral exploration, geotechnical characterisation, soil remediation studies and carbon capture and storage research. As a consequence of their ability to efficiently determine detailed, non-destructive elemental records in sediments and soils, scientific papers published since the year 2000 now number more than 1000.
