Interpretive Summary:

Technical Abstract: Global water supplies available for irrigation are declining while food demand continues to rise. Deficit irrigation offers a promising strategy to reduce water use with minimal impacts to yields, but is likely to have a range of impacts on soil nutrient cycling processes and climate change mitigation potential. To address this issue, we examined deficit irrigation effects on microbial communities, C and N cycling and greenhouse gas emissions. With a focus on sustainability and economic feasibility, deficit irrigation was investigated as an opportunity for farmers to meet the growing challenges of irrigated agriculture.
