Integrating environmental footprints and ecosystem economic performance to evaluate nitrogen management in intensive drip-irrigated potato production
Context
Excessive fertilizer application and poor agronomy management result in adverse environmental impacts and high environmental and economic costs for ecological restoration.
Objective
Analyzing the integrated effects of nitrogen (N) management on environmental footprints, human health, and ecosystem economic benefits (EEB) is essential to intensive potato cultivation under drip irrigation in Northwest China.
Methods
In this study, field experiments were conducted from 2018 to 2020 to evaluate environmental footprints and EEB based on the life cycle assessment (LCA), and a random forest algorithm was used to identify the importance of indicators to N and carbon (C) footprints. The N fertilizer levels were denoted as no N fertilizer application (Control), farmer practice (FP), and optimized N management (OM) based on N-balance principles, soil mineral N, and target yield.
Results and conclusions
The results revealed that OM treatment remarkably reduced reactive N (Nr) losses, greenhouse gas (GHG) emissions, environmental footprints, and ecosystem costs and increased human health and net EEB potentials per tonne or hectare of potato production. The OM treatment achieved 47.8 %, 27.7 %, 48.8 %, 30.4 %, and 42.9 % lower Nr losses, GHG emissions, N footprint, C footprint, and ecological costs, and 19.6 % higher N-derived net EEB compared to the FP treatment, respectively. The N leaching to the N footprint and N fertilizer to the C footprint were the most critical indicators and gained the highest importance scores. The decreased environmental footprints and increased EEB of OM treatments matched environmentally sustainable demand more than the FP treatment.
Significance
Integrating management measures and optimized N fertilizer rates have significant potential for environmental impacts and sustainable development in an intensive potato system under drip irrigation.
期刊介绍：
Agricultural Systems is an international journal that deals with interactions - among the components of agricultural systems, among hierarchical levels of agricultural systems, between agricultural and other land use systems, and between agricultural systems and their natural, social and economic environments.
The scope includes the development and application of systems analysis methodologies in the following areas:
Systems approaches in the sustainable intensification of agriculture; pathways for sustainable intensification; crop-livestock integration; farm-level resource allocation; quantification of benefits and trade-offs at farm to landscape levels; integrative, participatory and dynamic modelling approaches for qualitative and quantitative assessments of agricultural systems and decision making;
The interactions between agricultural and non-agricultural landscapes; the multiple services of agricultural systems; food security and the environment;
Global change and adaptation science; transformational adaptations as driven by changes in climate, policy, values and attitudes influencing the design of farming systems;
Development and application of farming systems design tools and methods for impact, scenario and case study analysis; managing the complexities of dynamic agricultural systems; innovation systems and multi stakeholder arrangements that support or promote change and (or) inform policy decisions.
