PhD Opportunity: The Role of Phosphorus in Mitigating Nitrous Oxide Emissions from Agricultural Soil

Mohammed VI Polytechnic University is an institution dedicated to research and innovation in Africa and aims to position itself among world-renowned universities in its fields

The University is engaged in economic and human development and puts research and innovation at the forefront of African development. A mechanism that enables it to consolidate Morocco's frontline position in these fields, in a unique partnership-based approach and boosting skills training relevant for the future of Africa.

Located in the municipality of Benguerir, in the very heart of the Green City, Mohammed VI Polytechnic University aspires to leave its mark nationally, continentally, and globally.

We invite applications for a fully funded PhD position focused on understanding the role of phosphorus (P) in reducing nitrous oxide (N₂O) emissions from agricultural soils. This interdisciplinary project lies at the intersection of soil science, environmental chemistry, and sustainable agriculture, addressing one of the most pressing challenges in climate-smart farming.

Nitrous oxide is a potent greenhouse gas with a global warming potential nearly 300 times that of carbon dioxide. It is largely emitted from agricultural soils through microbial processes, particularly under conditions of high nitrogen input and suboptimal nutrient balance. While nitrogen management has received considerable attention, the role of phosphorus in influencing microbial dynamics and N₂O production remains underexplored.

This project aims to investigate how different phosphorus levels and forms affect soil microbial communities, nitrogen cycling, and N₂O emissions. The successful candidate will conduct controlled laboratory incubations, field experiments, and employ molecular techniques to disentangle the biogeochemical interactions between phosphorus and nitrogen in soil systems.

Key Objectives:

• Evaluate how phosphorus availability influences nitrous oxide production pathways depending on soil properties and background fertility.
• Examine changes in microbial communities and functional genes involved in N transformation under different P regimes.
• Develop strategies for integrated nutrient management to minimize greenhouse gas emissions while maintaining crop productivity.

This PhD project is a collaboration between UM6P and external partners in Ireland and Denmark. The candidate will have the opportunity to work with a dynamic team of soil scientists, microbiologists, and climate researchers, and will gain hands-on experience with advanced analytical tools through short visits to partner institutions. A background in soil science, microbiology, environmental science, or a related discipline is essential.
