Work Package 1.4
This WP focuses on the development of farm-level N management software for decision support to non-experts, and production of guidance for policymakers. Building on work by NEWS India-UK on electronic leaf colour sensing and on the ‘Cool Farm Tool’, the team will deliver a free-to-use Nitrogen App made available through the Cool Farm Platform. The App will support decision making on fertilizer and manure/urine practices, including leaf colour sensing by the phone camera to help tune fertilizer/urine inputs and timing. The App will be parameterised using field data from WP2.1 for deployment in WP2.2, evaluating a range of nitrogen interventions, and identification of good practices as a function of farm location and typology. Testing of the App will consider acceptability, cost-effectiveness and reliability. The findings, together with input from hub experts, will inform policy guidance as a South Asian contribution to INMS. The published guidance (following UNECE standards of TFRN14 and experience of GPNM), will also be delivered as a web-based tool.
Work package level Specific objectives:
- Provide effective tools for N management to South Asian producers
Work package level-specific questions or hypotheses
- What N management apps exist for South Asia and how effective are they?
- What are the most effective field scale interventions to improve N management and how do they vary geographically?
- To what extent is efficient N use compatible with low GHGs and sustainable water use?
