e-infrastructure Roadmap for Open Science in Agriculture

A bibliometric study

The e-ROSA project seeks to build a shared vision of a future sustainable e-infrastructure for research and education in agriculture in order to promote Open Science in this field and as such contribute to addressing related societal challenges. In order to achieve this goal, e-ROSA’s first objective is to bring together the relevant scientific communities and stakeholders and engage them in the process of coelaboration of an ambitious, practical roadmap that provides the basis for the design and implementation of such an e-infrastructure in the years to come.

This website highlights the results of a bibliometric analysis conducted at a global scale in order to identify key scientists and associated research performing organisations (e.g. public research institutes, universities, Research & Development departments of private companies) that work in the field of agricultural data sources and services.

Quantitative Analysis of Soil Organic Carbon Using Laser-Induced Breakdown Spectroscopy: An Improved Method


Standard laser-induced breakdown spectroscopy (LIBS) offers a potentially rapid, accurate, field-portable, and low-cost technique for the measurement of C content in soil samples. Neutral and singly ionized Fe lines form significant interferences, however, that can compromise the LIBS C measurement. In this study, the 247.8-nm line of atomic C (C I) was examined in detail to assess the effect of potential elemental interferences. These interferences and their spectral and temporal signatures were evaluated using control graphite and Fe oxide samples. A combination of high dispersion and appropriate time gating of the LIBS signal was found to generate very high signal/noise ratio spectra using low laser powers and therefore, allowed accurate determination of the C content down to the subpercent level in the presence of Fe interferences. Although the contribution of one singly ionized Fe line cannot be entirely eliminated, a method to quantitatively assess the contribution of this line was developed. The new technique was tested on soil samples with organic C content in the 0.5 to 3% (w/w) range, and a strong correlation of the LIBS C signal with measurements made by the thermal oxidation, dry combustion method was observed. The findings reaffirm the utility of standard LIBS for rapid and accurate laboratory measurement of soil C and the potential use of standard LIBS with further study and development for assessing soil C in situ.
