“…As a result, SOM shows signs of stability, not because of its strength, but because of the temporary inaccessibility to microorganisms (Ekschmitt et al, 2005; Semenov & Kogut, 2015). One cannot ignore the fact that in aggregates >5.0 mm in size, the protection of SOC can be due to the limitation of oxygen status and a decrease in the availability of water, the geometry of pores that limit the activity of decomposers (Bhattacharyya et al, 2021; Feng et al, 2018; Nichols & Halvorson, 2013; Rani, 2021; Semenov & Kogut, 2015). The strength of bonds between clay minerals and organic matter is another mechanism for stabilizing soil organic carbon (Hernandez‐Soriano et al, 2018; Mustafa et al, 2021; Singh & Benbi, 2021).…”

“…At the same time, the soil microbial community, which has adapted to stressful influences, is in a stable state, while SOC, MB‐SIR, CO 2 ‐C production and, accordingly, the mineralization activity are in relative equilibrium with the newly formed agroecological conditions. This slow metabolism is a consequence of both physical and chemical stabilization of organic matter in the soil (Bhattacharyya et al, 2021; Joergensen et al, 1990; Rani, 2021; Singh & Benbi, 2021). Carbon is stabilized by isolation in macroaggregates, where it is inaccessible to soil microorganisms and enzymes.…”

“…Clay and silt are important mechanisms for stabilizing the carbon pool in soil (Das et al, 2022; Singh & Benbi, 2021; Wang et al, 2021). Chemical protection of SOC by clay minerals occurs mainly through adsorption reactions: cation bridge formation, anion exchange, hydrogen bonding, van der Waals interaction, co‐precipitation of organometallic complexes, ligand exchange and hydrophobic bond interactions (Rani, 2021; Sarkar et al, 2018). The findings are consistent with the data of Anderson and Domsch (1990) and Anderson (2003).…”

The presence of aggregates of various sizes in the soil is an important condition for soil carbon sequestration. In this system, microbial biomass is a key link. This work was devoted to the study of the influence of land use systems on the distribution of SOС, MB-SIR, microbial activity and eco-physiological indices (qCO 2 , QR, MB-SIR/SOС and qCO 2 /SOС) in relation to the size of soil aggregates. The distribution of SOС, MB-SIR and mineralization activity among the aggregates was heterogeneous. In the soil of crop rotation, high mineralization activity and MB-SIR were found in the aggregates 0.5-0.1 mm, in the monoculture soil in aggregates <0.1 mm and in the control soil in the aggregates 1-0.25 mm. There was a general trend towards a decrease in microbial activity, MB-SIR and SOС availability with an increase in aggregate size. In agricultural soils, microbial activity was determined by large aggregates (>5 mm), while in the control soil, by the aggregates 5-1 mm. Depending on the type of site and the size of aggregates, the differences in microbial metabolism were revealed. The qCO 2 and QR values decreased, and the MB-SIR/SOС and qCO 2 /SOС increased in the series: control soil > crop rotation > monoculture. In the control soil, the values of the ecophysiological indices decreased with decreasing aggregate size. And vice versa, in agricultural soils, these parameters were the highest in the microaggregates (<0.25 mm). The monoculture soil, in contrast to the control soil and crop rotation soil, turned out to be more energy efficient.

“…It plays a pivotal role in maintaining soil moisture by enhancing water retention capacity and preventing soil compaction. Moreover, the organic matter in FYM serves as a carbon sink, aiding in carbon sequestration and contributing to the mitigation of climate change (Rani et al 2022;Yadav and Ramakrishna 2023). This aligns with the broader goal of creating sustainable agricultural systems that are resilient to climate uctuations (Rani et al 2022).…”

Soil health plays a pivotal role in ensuring sustainable agriculture, particularly in the face of climate change challenges. This field study investigated the potential synergistic effects of biochar and farm yard manure (FYM) applications on soil properties, nutrient availability, cotton growth, and yield in cotton. Our findings highlight the promising impact of biochar and FYM, each applied at a rate of 5 t ha-1, on various aspects of soil and crop performance. Results indicated the substantial reduction in soil temperature, especially in the biochar + FYM treatment (27.2°C) compared to control treatment (37°C). This reduction in soil temperature created a favorable microclimate for cotton plants, mitigated heat stress and fostered healthier growth. Likewise, biochar + FYM combination showed a minor decrease in soil pH (pH 7.7) compared to control treatment (pH 8.1). Furthermore, the application of biochar + FYM significantly increased soil organic carbon (0.89%) and organic matter content (0.97%) as compared to sole application of biochar or FYM. Additionally, macro and micronutrient availability, including nitrogen (N), phosphorus (P), potassium (K), copper (Cu), manganese (Mn), zinc (Zn), and iron (Fe), substantially increased after the application of these amendments, with the biochar + FYM treatment exhibiting the highest values. The positive impact of these amendments extended to cotton plant growth, with increased plant height (175 cm), a greater number of bolls per plant (43), and heavier open boll weight (3.18 g) observed in the biochar + FYM treatment. Moreover, improvements in ginning out turn (GOT), staple length, and fiber uniformity were notable outcomes of biochar and FYM applications, particularly in combination. Fiber fineness and strength remained consistent. In addition to their soil and crop benefits, the application of biochar and FYM led to reduced irrigation requirements and enhanced crop water use efficiency (WUE), promoting more sustainable water management practices in cotton cultivation. This research highlights the potential synergy between biochar and FYM as a promising approach to enhance soil health and mitigate the impacts of climate change in cotton production.
