Summary
This systematic review synthesises evidence on sustainable intensification strategies for maize-wheat systems in South Asia, examining how conservation tillage, residue retention, and optimised nutrient management interact to influence soil health, productivity and environmental outcomes. The analysis appears to integrate food security, renewable energy, and climate mitigation objectives—three competing demands in cereal-based farming systems. The authors likely conclude that integrated rather than isolated management interventions offer the greatest potential to balance yield, soil quality and carbon efficiency under resource-constrained conditions.
UK applicability
While the maize-wheat system and soil/climate context differ substantially from UK arable conditions, the methodological framework for optimising tillage-residue-nutrient trade-offs is potentially transferable to temperate cereal rotations. UK applicability would depend on whether the review addresses winter wheat systems and whether soil carbon and energy metrics are relevant to UK net-zero and soil health policy targets.
Key measures
Soil organic carbon, nutrient availability, grain yield, energy productivity, greenhouse gas emissions, carbon footprint
Outcomes reported
The study evaluated integrated management strategies combining tillage practices, crop residue handling, and nutrient application in maize-wheat systems, with outcomes measured across soil health, crop productivity, energy use efficiency, and carbon footprint metrics.
