“…Another study conducted by Ali et al [40] reported that among different crop residue management methods, incorporating residue notably boosted grain and straw yields of rice and wheat, with increased nitrogen, phosphorus and potassium uptake in wheat by 15%, 11% and 11%, respectively. Thind et al [41] demonstrated that retaining residue on the surface in zero tillage resulted in significantly higher wheat grain yields compared to conventional tillage with straw removal.…”

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.

The in-situ management of rice straw incorporation has become an essential practice in the rice–wheat cropping system with the growing adoption of super-seeder among farmers. While this equipment facilitates straw incorporation, nutrient immobilization from organic residues during decomposition poses a challenge to production. This study investigates the effect of bio-decomposer, nitrogen (N) level, and N scheduling on on various parameters in super-seeder sown wheat over two consecutive years (2020–21 and 2021–22). The experiment was laid in split-split-plot design without (B0) and with (B1) bio-decomposer, two nitrogen levels 150 (N1) and 180 (N2) kg ha−1 and three N splits (%) viz., 50: 25:25 (S1), 40: 30: 30 (S2), and 30:35:35 (S3) and replicated thrice. Results indicate significantly higher N concentration and uptake at pre- and post-anthesis with N2 and S1 compared to N1, S2, and S3. Post-anthesis N accumulation (post-NA) and remobilization (NR) were notably higher with N2. Dry matter accumulation (DMA) at anthesis and harvest significantly increased with N2 and S1 compared to N1 and S3, leading to significantly improved grain yield by 8.3% and 10.9% (two years mean). Soil urease activity (UA) significantly increased with bio-decomposer, N2, and S1 compared to B0, N1, and S3 at 30 and 60 DAS. Moreover, bio-decomposer enhanced soil microbial biomass carbon (SMBC). These findings underscore the importance of higher N levels with a greater basal N proportion in mitigating N stress and promoting sustainable wheat productivity. It also highlight the significance of effectively utilizing and conserving rice residue in the rice–wheat system.
