Dr. Ambreen Bhatti

Dr Bhatti is funded as a visiting scientist for two years (2016 and 2017) funded by LEARN.

Her topic or research is “An investigation of controls on the dynamics of the C and N cycling in soils under permanent grasslands”.

The research

Dr Bhatti will work with some soil samples to which biochar has been amended.

Biogeochemical models used to simulate greenhouse gas (GHG) exchange and carbon cycling in terrestrial ecosystems generally identify three pools of soil organic matter (SOM) with different turnover times: active (0.5-1 year), slow (10-50 years) and resistant (1000-5000 years). Each of these have different agronomic and environmental implications.

In this study we aim to get a deeper understanding on

  1. the characteristics of soil organic matter in these different pools, and
  2. how these characteristics relate to their mitigation potential for N2O and CO2 emissions from soils.

This research will take advantage of previous and on-going research on soil carbon and N2O emissions funded by the NZAGRC and other agencies so that studies are complemented and synergies maximised.

Dr Bhatti's background

Dr Bhatti, originally from Pakistan, has a master's from the University of Arid Agriculture in Pakistan and a PhD from the University of York.

Her research interests include:

  • Soil and water carbon cycling
  • Effect of land and water use on carbon distribution, soil quality and its storage in deep layers.
  • Effect of C cycle on N cycle.
  • Effect of soil and water C and N on plants
  • Flow of C and N in plants
  • Use of excessive nitrogen fertilizers in semi arid and arid grasslands, parks, lawns and Golf courts and their impact on soil, plants and water quality of the region and impact on biodiversity.
  • Effect of management practices in on the level of Nitrogen in soil and causes of N and C pollution and how to control it.
  • Impact of soil pollution on underground water and to understand the mechanism of drainage in under soil layers by small moles and its further effect on adjacent streams water quality and underground water resources.
  • Turf Grasses
