Lei Zhong starts his LEARN co-funded PhD scholarship

Lei Zhong is undertaking a PhD considering the "effect of grazing on nitrous oxide emissions from nitrification and denitrification processes from temperate grasslands". Lei is enrolled in his PhD at the Graduate University of the Chinese Academy of Sciences and works under the primary supervision of Ecology Professor Yanfen Wang, an expert in grassland ecosystem ecology, biogeochemistry, and carbon and nitrogen cycling. The PhD programme is based on the knowledge that animal grazing affects the carbon and nitrogen cycling in grassland ecosystems, but the research that is available on the impact of grazing cattle on steppe grasslands in northern China is conflicting.

 

Lei explains that 'there is no assessment to date on the effects of cattle grazing on nitrification and denitrification processes, and on nitrous oxide emissions from meadow steppe grasslands in Northern China, especially the effects of animal excreta on nitrous oxide emissions. The primary objective of my research is to quantify the nitrous oxide emissions through nitrification and denitrification processes from soils from meadow steppe grassland in northern China and managed temperate grassland in New Zealand". Lei goes on to say that "the field and laboratory data collected will be used to model nitrous oxide emissions using a process-based ecosystem nitrogen model".

The advantages of having a LEARN co-funded scholarship for Lei is an opportunity to undertake part of his PhD in New Zealand; undertaking extensive field work and analysis during that time.  Lei will spend 16 months under the supervision of Dr Frank Li, an expert in agro-ecosystem modelling and analysis at AgResearch, Palmerston North and Dr Saman Bowatte a expert soil microbial ecologist.
