Summary
This systematic review synthesises evidence on the ecological and agronomic impacts of straw return in crop production systems. The authors examine how incorporating crop residues influences soil biological communities, nutrient cycling processes, and crop performance, addressing the trade-offs between organic matter accumulation and potential challenges such as nutrient mineralisation delays and disease pressure. The review likely concludes that straw return offers net benefits for soil health and sustainability, with context-dependent effects on yield depending on management and environmental factors.
UK applicability
Findings are likely applicable to UK cereal production systems, particularly regarding soil carbon sequestration targets and sustainable intensification goals. However, UK conditions (cooler temperatures, higher rainfall) may alter decomposition rates and disease dynamics compared to studies from warmer climates, requiring adaptation of management recommendations.
Key measures
Soil microbial biomass and diversity, soil organic carbon, soil physical properties (aggregate stability, porosity, bulk density), nutrient availability, crop yield, soil-borne disease incidence
Outcomes reported
The review synthesises evidence on how straw return practices influence soil microbial communities, nutrient cycling, physical soil properties, and resulting crop yields across varied agricultural contexts. It likely examines both positive effects (organic matter, soil structure) and potential challenges (pest/disease management, nutrient immobilisation).
