“…Soil microbial respiration was used as an indicator of microbial activity in the soils of the three treatments. Our findings are in accordance with the literature, that soil microbial respiration is typically higher in NT when compared to reduced tillage (SC in this case) or P [50,51].…”

Long-term cultivation experiments are gaining more attention due to the possibility of following the changes in soil parameters (e.g., soil organic carbon (SOC), stock and soil health indicators, etc.). Our objective was to assess the status of soil in an 18-year-old tillage experiment after almost two decades of systematic tillage. In this research, soil physical (bulk density, moisture content), chemical (pH, SOC), and biological properties (soil microbial respiration, abundance, biomass, species composition of earthworms, yield) were used as indicators in three soil cultivation methods representing different degrees of disturbance (no-till—NT; shallow cultivation—SC; and ploughing—P). Based on our results, there were significant differences in bulk density (NT > SC, P) in 0–10 cm, and NT > P in deeper layers (10–20, 20–30, 30–40 cm), while the SOC content in 0–10 cm was the highest in NT (2.5%), followed by SC (2.4%) and P (2.0%). Soil microbial respiration was significantly greater in NT than in SC and P. The abundance and biomass of earthworms was the highest in NT (189 ind m−2, 41.26 g m−2), followed by SC (125 ind m−2, 36.9 g m−2) and P (48 ind m−2, 7.4 g m−2). We concluded that NT offered a beneficial habitat for earthworms and microorganisms and a high SOC storage capacity; however, bulk density was less convenient due to soil compaction in our experiment. Therefore, SC can be used as an alternative approach for sustainable soil tillage.

“…In contrast, a long-term experiment conducted by Jha et al [69] over a period of fifty years did not align with previous studies, wherein higher respiration rates were seen in treatments where stubble remained after harvesting, likely due to more organic material being available in the soil. However, in this study, there was not a notable difference in the overall organic carbon content between treatments where stubble was burnt and those where it was not.…”

Stubble burning, a common agricultural practice, has gained significant attention due to its adverse effects on soil properties and environmental sustainability. The in-situ burning of stubble, especially in the context of the rice-wheat cropping system, can significantly alter the physical and chemical properties of soil, particularly in the topsoil layer. The factors contributing to crop residue burning in India include time constraints between successive crops which necessitates the need to clear fields quickly and limited access to mechanized equipment for residue management. As a result, many farmers resort to burning crop residues as a quick and cost-effective method to clear fields for the next planting season. In situ stubble management techniques offer sustainable alternatives to address these issues and promote soil health as this once-dismissed residue transforms into a strategic tool for nurturing soil vitality. This review provides a comprehensive analysis of the impact of stubble burning on various soil properties, especially in the context of burning of rice residues. It synthesizes existing literature and research findings to elucidate the interactions between stubble burning and soil health and evaluates mainly the long-term consequences of stubble burning on soil fertility and productivity. Based on the findings, crop residue burning disrupts soil ecosystems, impairs nutrient cycling, decreases soil fertility and compromises ecosystem resilience, leading to long-term soil degradation while the short-term effects remain less understood across different contexts.

“…This could point towards greater stability of glomalin against mineralization than other soil organic matter. Jha et al [66] found a positive correlation between the mineralization process (release of nitrogen from organic bonds) and EEG content. Authors further concluded that EEG content could be a certain criterion for estimating potential nitrogen mineralization from organic bonds.…”

The Influence of Organic and Mineral Fertilizers on the Quality of Soil Organic Matter and Glomalin Content

The influence of different fertilizers (mineral/organic) on the quantity and quality of soil organic matter was monitored in long-term stationary experiments (27 years) with silage maize monoculture production on Luvisol. The main aim of this study was to investigate the relationship between easily extractable glomalin (EEG), total glomalin (TG), and parameters commonly used for the determination of soil organic matter quality, i.e., the content of humic acids (CHA), fulvic acids (CFA), and potential wettability index (PWI). A significant correlation was found between EEG content and CSOM content, humic acid content (CHA), humic acid/fulvic acid ratio (CHA/CFA), PWI, and index of aromaticity (IAR). Furthermore, the contents of EEG and TG correlated with soil organic carbon (CSOM). Periodical application of sewage sludge and cattle slurry increased the content of glomalin in soils. From the results, it is obvious that data about glomalin content can be used to study soil organic matter quality. A more sensitive method (a method that reacts more to changes in components of soil fertility) seems to be the determination of EEG rather than TG. The factors supporting use of EEG extraction in agronomic practice are mainly the substantially shorter time of analysis than TG, CHA, and CFA determination and lower chemical consumption. Furthermore, the PWI method is even suitable for studying soil organic matter quality. On the other hand, the humus quality ratio (E4/E6) does not provide relevant information about soil organic matter quality.
