Akinson Tumbure

Post-Doctoral Research Fellow – Beyond Peat Project

Research Interests

My research interests are guided by the desire to propel commercial agriculture towards more environmentally sustainable and organic based technologies. I am intrigued with chemical, microbiological and physical processes that affect plant nutrition and how these processes can be sustainably utilised for crop growth in soil and peat free growth media. Over the years I have done research on

  1. Alternative phosphorus fertilisers which include biochar composites (made from agro-wastes and rock phosphate) and struvites (made from municipal and food processing wastewater).
  2. Beneficial microbial-plant interactions as alternative sources of nitrogen for legume crops.
