The chemical composition and dynamics of organic amendments to supply phosphorus for improved crop production

Project opportunity

This Earmarked Scholarship project is aligned with a recently awarded Category 1 research grant. It offers you the opportunity to work with leading researchers and contribute to large projects of national significance.

The northern grains region is a major producer of food and fibre in Australia. However, crop yields in this region are often reduced due to an insufficient supply of phosphorus in soil. There is increasing attention on the use of 'organic' amendments as a sustainable phosphorus source for crop production. However, little is known on the chemical composition and phosphorus release dynamics of organic amendments in Australia.

This project aims to understand the soil processes that govern the turnover of phosphorus from organic amendments in soil and its capacity to supply phosphorus to crops. A multidisciplinary approach will be used to investigate the chemical composition and nutrient dynamics of organic amendments in a range of soils within the northern grains region of eastern Australia. The successful candidate will gain skills in a broad range of experimental designs, analytical techniques, and research environments. Project outcomes will greatly benefit primary producers, and lead to improved outcomes for agriculture and the environment.

Scholarship value

As a scholarship recipient, you'll receive: 

  • living stipend of $32,192 per annum tax free (2023 rate), indexed annually
  • tuition fees covered
  • single Overseas Student Health Cover (OSHC)

Preferred educational background

Your application will be assessed on a competitive basis.

We take into account your

  • previous academic record
  • publication record
  • honours and awards
  • employment history.

A working knowledge of agriculture or environmental science would be of benefit to someone working on this project.

The applicant will demonstrate academic achievement in the field(s) of soil science or plant nutrition and the potential for scholastic success.

A background or knowledge of soil chemistry is highly desirable.

Latest commencement date

If you are the successful candidate, you must commence by Research Quarter 4, 2022. You should apply at least 3 months prior to the research quarter commencement date.

If you are an international applicant, you may need to apply much earlier for visa requirements.
