Summary
This 2023 field study examines how coordinated optimisation of nitrogen and water management in greenhouse vegetable production can reduce greenhouse gas emissions whilst maintaining or improving productivity. The research contributes to understanding the trade-offs and synergies between resource efficiency and climate mitigation in protected cropping systems, a production method increasingly important in intensive horticulture. The findings suggest that management practices tailored to greenhouse conditions can simultaneously improve environmental outcomes and economic viability.
UK applicability
The findings are potentially relevant to UK protected horticulture, which has been expanding and faces pressure to reduce both water stress and nitrogen pollution under Water Resources Management and Environmental regulations. However, the study was likely conducted in China's warmer climate zones, so agronomic parameters (soil type, growing seasons, cultivars) may differ substantially from UK greenhouse conditions.
Key measures
Greenhouse gas emissions (particularly N₂O), water use, nitrogen application rates, crop yield, nitrogen use efficiency, soil nitrogen dynamics
Outcomes reported
The study assessed the effects of optimised nitrogen and water management strategies on greenhouse gas emissions, crop yield, and resource use efficiency in protected vegetable production. The research likely measured nitrous oxide emissions, water consumption, nitrogen uptake efficiency, and vegetable yield under different management regimes.
