Summary
This review, published in Advances in Agronomy, synthesises the scientific evidence on the use of catch crops and green manures as biological tools for managing nitrogen in temperate farming systems. It likely evaluates the capacity of these crops to reduce nitrate leaching, retain nitrogen over winter, and release it for uptake by subsequent cash crops through mineralisation. The paper is considered a foundational reference in the field of sustainable nitrogen management in arable rotations.
UK applicability
The findings are directly applicable to UK arable farming conditions, where nitrate leaching into water courses is a significant regulatory and environmental concern; the use of catch crops aligns with agri-environment schemes and the UK's post-CAP farming policy frameworks, including Sustainable Farming Incentive options.
Key measures
Nitrogen uptake (kg N/ha); nitrate leaching losses (kg N/ha); nitrogen mineralisation rates; crop nitrogen use efficiency; green manure biomass nitrogen content
Outcomes reported
The review examines how catch crops and green manures influence nitrogen cycling, nitrate leaching reduction, and nitrogen availability to subsequent crops in temperate agricultural systems. It likely reports on nitrogen uptake efficiency, mineralisation rates, and the agronomic performance of various species used as biological nitrogen management tools.
