“…This was clearly observed across different studies with varying magnitudes, which employ different plant residues (Figure 1A). However, certain discrepant reports were also noted in our meta‐analysis, which deviates from the central notion of increased soil pH (Bramble et al., 2021; Clark et al., 2007; Lauricella et al., 2021; Marx et al., 2002; Tang & Yu, 1999; J. M. Xu et al., 2006; R. K. Xu & Coventry, 2003; Yan et al., 1996; Yuan, Xu, Wang, & Li, 2011). These studies report negative or zero effects in pH shifts.…”

Background The effect of plant residues on the pH of agricultural acid soil varies markedly across numerous studies, which has been attributed to differences in plant residue characteristics, soil initial properties, and experimental conditions. Aims The aim of this study was to address the need to form a unified framework for the relationship between plant residue incorporation and acid soil pH in agricultural systems. Methods A systematic compilation of data was performed through a keyword search in the Scopus database, which yielded 221 independent pairwise comparisons of soil pH across 23 published articles utilizing laboratory incubations. These data were then used to form a consensus on the effect of plant residue on acid soil pH via a meta‐analysis approach. Results Of the 221 pairwise comparisons, 91.4% of the cases showed a positive effect of plant residue in increasing acid soil pH. Overall, plant residue application significantly improved soil pH of acid soil (p ≤ 0.05) by 12.4% ± 1.0% regardless of the heterogeneity in plant, soil, and experimental attributes between studies. Our analysis also revealed that total alkalinity (≥ 80 cmol kg–1) and N (≥ 10 g kg–1) of plant residue provide the optimal ameliorative effect. This ameliorative effect is more pronounced in extremely acidic soil (pH 3.5–4.4) than at soil with pH > 5.5. Conclusions The insights gained through this meta‐analysis demonstrated the interplay between different plant residue, soil, and experimental attributes, which collectively influence the ameliorative effect of plant residue application to the pH of agricultural acid soil.

“…Consequently, the increase in C mineralisation should have increased the SOC_CO 2 emissions following the application of aglime (e.g., Dumale et al, 2011). However, the magnitude and dynamics of the C priming effect largely depend on the quality and initial content of C and the resulting nutrient supply to decomposing organisms (Bramble et al, 2021) together with pH dynamics. The potential decrease in SOC mineralisation following aglime application in this study related to lower CO 2 emissions could also be due to: (i) increased microbial C‐use efficiency, as soil microbial communities use less energy maintaining intracellular pH or there is a change in community composition (Pal et al, 2007), (ii) a more pronounced SOC stabilizing effect and calcium (Ca 2+ ) in the soil structure (Muneer & Oades, 1989; Wachendorf, 2015).…”

The functioning of the nitrous oxide (N2O) reductase enzyme involved in the last step of denitrification is pH sensitive, with an optimum of 6.8. A solution to mitigate N2O emissions would be to bring soil pH close to neutrality by adding agricultural liming products (aglime). Nevertheless, the influence of aglime on the soil greenhouse gas (GHG) balance (CO2–N2O) is a subject of debate, particularly when considering the fate of the carbon (C) derived from carbonates. Our objective was to investigate the results of the effect of calcium carbonate (CaCO3) aglime on the CO2–N2O balance. Sixteen cylinders of undisturbed acidic soil were taken from a sandy loam profile and incubated at 20°C for 107 days in anaerobic conditions (water‐filled pore space >60%). Eight limed treatment cylinders received 1.45 g of aglime on the soil surface (2 t NV ha−1) and 0.08 g of N (100 kg of N ha−1). Eight control treatment cylinders received only 0.08 g of N. N2O and CO2 fluxes were measured and converted into CO2 equivalents to perform a GHG balance calculation. Furthermore, soil and leachate properties were measured. Aglime application triggered a reduction of N2O emissions, probably due to an increase in soil pH at the beginning of the experiment, which would have led to the N2O reductase activation. High NO3−$$ {{\mathrm{NO}}_3}^{-} $$‐N content in the soil may inhibit the high N2O reduction potential in the limed treatment. CO2 emissions were unexpectedly lower in the limed treatment. Aglime addition did not enhance C mineralisation, which may be explained by the possible stabilisation of soil organic carbon. A significant 11.3% reduction of GHG emissions was observed in the limed treatment. Overall, our results show that a strategy of liming acidic agricultural soil could be implemented for its potential in GHG mitigation. Nevertheless, future in‐depth research is necessary to better understand the fate of the C brought about by aglime.

“…The strong evidence of humic-like substances generated from partial oxidation of lignocellulosic biomass was probably due to the condensation of intermediate compounds derived from the WAO process since the thermal degradation, hydrolysis, and oxidation of lignocellulosic material fragments into smaller-molecular-weight compounds lead to a complex reaction mechanism in this closed system, such as aromatization, polymerization, and deposition onto mineral content, thus avoiding organic degradation ,− (Scheme ). In this context, Bramble et al observed the reduction of OM mineralization (i.e., organic carbon) by application of limestone with organic byproducts, another important step to better understand the mechanism that regulates SOM mineralization by mineral phase interactions.…”

Wet air oxidation (WAO) of grape pomace, an organic waste generated in massive amounts worldwide and with low biodegradability due to phenol-acid content, was performed to evaluate the potential production of an organomineral fertilizer with biostimulant properties. The synergistic effect of co-processing kimberlite rock powder, a diamond mine tailing, was tested as a potential waste-derived catalyst due to its ferrous iron content and as a potential carbon sink due to its alkaline earth-silicate content. The gaseous, liquid, and solid phases were characterized by gas chromatography, wavelength-dispersive X-ray fluorescence, pH, loss on ignition, thermogravimetric analysis, attenuated total reflectance Fourier-transform infrared spectroscopy, calcimetry, and turbidity, and the results were also subjected to bivariate and multivariate analyses (Pearson correlation coefficient and principal component analysis) to uncover data patterns. The products obtained from WAO were evaluated in bioassays for their soil amendment properties: one assay as a nutrient source to alfalfa (Medicago sativa L) and another assay with soybean (Glycine max L. Merrill) under abiotic stress. The results revealed that temperature and kimberlite play an important role in the oxidation performance of steadfast humic-like substances, and kimberlite is a sink for part of the CO2 that is produced during WAO via mineral carbonation. The WAO products were found to possess beneficial nutrients and properties as soil amendments in terms of sustaining early plant development and alleviating salinity stress.
