Project description
Better fertiliser use for sustainable agriculture
The global agricultural sector faces a pressing challenge: the declining efficiency of nitrogen (N) and phosphorus (P) fertilisers. Despite the widespread use of ammonia synthesis and phosphate mining, the efficiency of these inputs has dwindled over time, contributing to environmental issues like soil acidification, eutrophication, and phosphate depletion. Fertiliser use has surpassed sustainable limits, but existing methods for measuring efficiency often fail to account for regional differences. Supported by the Marie Skłodowska-Curie Actions programme, the OFUC project is analysing trends in N and P use efficiency (NUE and PUE) from 1961 to 2020. By integrating machine learning and climate change scenarios, it seeks to optimise fertiliser use, enhance crop yields, and reduce environmental harm.
Objective
This research aims to enhance global agricultural sustainability by improving nitrogen (N) and phosphorus (P) use efficiency (NUE and PUE) in major crops. While the widespread adoption of ammonia synthesis and industrial phosphate mining has significantly boosted the use of inorganic N and P fertilizers, their efficiency has declined over time. From 1961 to 2018, the dramatic increase in fertilizer application surpassed sustainable thresholds, leading to environmental challenges such as phosphate rock depletion, eutrophication, and soil acidification. Existing knowledges for assessing NUE and PUE often overlooks regional differences and specific agricultural practices, limiting their effectiveness.
This project addresses these gaps through three key work packages. First, the N(P)UEdiff method will be used to analyze historical NUE and PUE trends from 1961 to 2020 for major crops worldwide, identifying critical breakpoints. Second, machine learning models will predict the spatial distribution of NUE and PUE from 2000 to 2020, factoring in environmental and management variables to reveal driving factors. Lastly, future climate change scenarios will be integrated into these models to project NUE and PUE changes through 2100 and propose optimal agronomic strategies.
The innovative combination of the N(P)UEdiff method with dynamic data across 205 countries allows for the first comprehensive analysis of NUE and PUE trends and projections. This project will offer valuable insights for optimizing fertilizer use, increasing yields, reducing costs, and mitigating environmental harm, supporting global food security. The hosts expertise in global change ecology, coupled with the fellow's agroecology background, ensures successful implementation, while the interdisciplinary approach and open science practices will maximize the researchs impact and dissemination.
