“…Figure 3 b compares the abundance of acid sites in humic extracts ( M T,HS S ) and DOM ( M T,DOM ). The acid sites abundance, expressed in mol kg compost −1 , was calculated using the proton titration values M T (mmol g C −1 ) from Table S2 [ 16 ] and the carbon content (expressed in g C kg compost −1 ) of each extract ( C HS or C DOM ).…”

“…The proton titrations of the different extracts, extraction yields and carbon content of the compost of algae (CA) and the uncomposted organic fertiliser (FLW) were carried out as described in López et al (2021) [ 16 ]. The corresponding values from the extracts of all other composts used in this work were also presented in López at al.…”

The present work demonstrates the use of Cd2+ as a reactivity probe of the fulvic acids (FAs), humic acids (HAs) and dissolved organic matter (DOM) compost extracts. Significant differences were observed between the extracts, with the HA extract showing the highest reactivity. Comparing the different composts, the largest reactivity variation was again observed for HA then FA and finally DOM extracts. The Cd2+ binding extent was used to calculate the quality of composts and compared with a reference of uncomposted organic fertiliser (FLW), leading to the definition of an operational scale of compost quality. The parameter equivalent mass of fertiliser (mEF) was used for this scale sorted the seven composts from 0.353 to 1.09 kg FLW, for compost of sewage sludge (CSS) and vermicompost of domestic waste (CVDW), respectively. The significance of this parameter was verified through a correlation analysis between binding extent and the effect of compost application on lettuce crop growth in a field trial. The results demonstrate the potentiality of FA and HA extracts as markers of compost bioactivity and the use of Cd2+ as a reactivity probe.

“…The impact of the sort of raw materials and composting methods has been studied in assays performed on the compost [14][15][16]. The studies based on the characterization of compost may use single characterization techniques, such as elemental characterization [17][18][19] or TGA [20], or on more than one characterization technique, combining elemental characterization information with thermogravimetric results [21,22]; spectroscopic data [21,23]; physico-chemical parameters, including water retention and particle size [24][25][26][27][28]; chemometric analyses [23,24,29] or plant growth assays [26,27,30]. In a study with three composts and three vermicomposts, authors found that the C/N ratio was lower for vermicomposts [21].…”

“…There are few works that relate results from plant growth assays to the compost origin. Whereas seed germination and plant root growth were reported to be inhibited by compost from sewage sludge [26], seed germination was reported to be improved by composts from manure and domestic wastes [30]. In a plant growth study using cucumber, an increase in the weight of the fresh fruit was noticed when compost containing manure was used [27].…”

The potential of composts produced from different origin residues to be used in environmentally friendly agriculture is addressed in this work. Seven composts obtained from different raw materials and composting methodologies are compared using elemental, thermal and spectroscopic characterization data. Despite the stabilization of the organic matter in all composts being adequate for agricultural applications, they display distinct elemental and structural compositions. Likewise, the fertilisers have very different effects on lettuce growth. Despite the observed differences, some common features were found, namely a mass loss (TGA) of 25.2 g per mol C, association between groups of elements (Fe, Al, Ni, Co, Cr, Cu and S; Mg, Na, K and P, C, Coxi, N and Pb) and correlations between the amount of carbon nanostructures and the characteristic aromaticity parameters. These results suggest that the tuning of the compost features for specific cultures may be possible for sustainable food production.
