“…As reported by many researchers, organic Csequestration in soil could be enhanced by the chemical, physicochemical and biological protection to SOC through recalcitrance of SOC, facilitating the organo-mineral interaction, and protecting SOC from microbes andmicrobial decomposition, respectively (Barré et al 2014;Pramanik et al 2020). The main recommended management practices for enhancing the C-sequestration include conservation agriculture (Lal 2015;Ranjan et al 2021), conservation tillage , agroforestry (Hübner et al 2021), adoption of diversified cropping systems (Ngangom et al 2020), integrated nutrient management (Ghimire et al 2017;Gogoi et al 2021a, b), mulching (Ngangom et al 2020), improved grazing (Sarkar et al 2020Mattila et al 2022), and forest management (Pramanik et al 2020;Ameray et al 2021). Many approaches for managing soil Csequestration could be found in Table 1.…”

Global food production mainly depends upon the productive outcomes of the agricultural sector. Soils are the pool of nutrients required for plant growth. These nutrients directly enhance the crop yields and immune against the multiple biotic and abiotic stresses. These nutrient elements also supplement human food with these elements. It is a well-established fact that balanced nutrition results in the healthy growth of plants which can combat different stresses. Conservation agriculture is the key sustainable measure for increasing food security, alleviating poverty, biodiversity conservation, and safeguarding ecosystem services. Nano-fertilizers are also eco-friendly sources by maintaining a balance of C sequestration and N emissions in the environment. Nano-fertilizers, because of their unique properties, are now a promising approach to enhance soil, fertility, enhance plant growth, and improve soil C sequestration.

“…Although soil properties have decreased over the years due to improper management practices (Singh et al, 2019), the adoption of the best management practices (conservation tillage, nutrient management, etc.) enhanced SOC, available N, P, and K contents of the Himalayan soils (Gogoi et al, 2021).…”

Although agro-geotextile (AGT) emplacement shows potential to mitigate soil loss and, thus, increase carbon sequestration, comprehensive information is scanty on the impact of using agro-geotextiles on soil organic carbon (SOC) sequestration, aggregate-associated C, and soil loss in the foothills of the Indian Himalayan Region. We evaluated the impacts of Arundo donax AGT in different configurations on SOC sequestration, aggregate stability, and carbon management index (CMI) since 2017 under maize-based cropping systems on a 4% land slope, where eight treatment procedures were adopted. The results revealed that A. donax placement at 0.5-m vertical-interval pea–wheat (M + AD10G0.5-P-W) treatment had ∼23% increase in SOC stock (27.87 Mg·ha−1) compared to the maize–wheat (M-W) system in the 0–30-cm soil layer. M + AD10G0.5-P-W and maize–pea–wheat treatments under bench terracing (M-P-W)BT had similar impacts on SOC stocks in that layer after 5 years of cropping. The total SOC values in bulk soils, macroaggregates, and microaggregates were ∼24, 20, and 31% higher, respectively, in plots under M + AD10G0.5-P-W treatment than M-W in the topsoil (0–5 cm). The inclusion of post-rainy season vegetable pea in the maize–wheat cropping system, along with AGT application and crop residue management, generated additional biomass and enhanced CMI by ∼60% in the plots under M + AD10G0.5-P-W treatment over M-W, although M + AD10G0.5-P-W and (M-P-W)BT had similar effects in the topsoil. In the 5–15-cm layer, there was no significant effect of soil conservation practices on CMI values. Under the M + AD10G0.5-P-W treatment, the annual mean soil loss decreased by ∼92% over M-W treatment. We observed that CMI, proportion of macroaggregates, aggregate-associated C, labile C, total SOC concentration (thus, SOC accumulation rate), and mean annual C input were strongly correlated with the mean annual soil loss from 2017 to 2021. The study revealed that the emplacement of an A. donax mat and incorporation of a legume in a cropping system (M-W), conservation tillage, and crop residue retention not only prevented soil loss but also enhanced C sequestration compared to farmers’ practice (M-W) in the Indian Himalayas. The significance of this study is soil conservation, recycling of residues and weeds, and climate change adaptation and mitigation, as well as increasing farmers’ income.

“…In India, the addition of manures in soil is a traditional practice that has been followed for a long time (Gogoi et al 2021). Furthermore, because atrazine is a popular herbicide in maize, sorghum, sugarcane, and other crops and is applied as a pre-and early-post emergence.…”

The behaviour of pesticides applied during cultivation of crops is affected by usage of amendments like farm yard manure (FYM) and vermicompost (VC) during land preparation. Among pesticides, atrazine, a widely used herbicide in many crops, was analysed for its kinetics and sorption behaviour through the addition of FYM and VC in sandy loam soil. The pseudo-second order (PSO) model best ts kinetic results in the recommended dose of FYM and VC mixed soil. Atrazine was more sorbed onto VC mixed soil than FYM mixed soil during adsorption. Both FYM and VC (1, 1.5, and 2%) increased atrazine adsorption, but the effect varied with dosage and type of amendment. The Freundlich adsorption isotherm adequately explained atrazine adsorption in soil/soil+ (FYM/VC) mixtures, and adsorption was highly nonlinear. The values of Gibb's free energy change (ΔG) were negative for both adsorption and desorption, suggesting sorption was exothermic and spontaneous in nature. The results revealed that the application of amendments used by farmers interferes with the availability, mobility, and in ltration of atrazine in the soil. Therefore, the ndings of this study suggest that amendments like FYM and VC can be effectively used to minimize the residual toxicity of atrazine treated ago-ecosystems in tropical and sub-tropical regions.
