How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I completed my PhD in Agriculture from University of Sydney. My research interest is microbial and plant response to carbon, nitrogen and phosphorus addition, and their contribution to nitrogen transformation (such as mineralization, immobilization, N2O emission, NO3- leaching) in soil. I completed my Bachelor (with Honours) and Masters in Soil, Water and Environment from University of Dhaka, Bangladesh. I did my second Masters in Environmental Science from University of Sydney, Australia.

The quantity and chemical composition of soil organic carbon (C) are primary factors controlling the growth and activity of soil microorganisms. However, availability of phosphorus (P) can also limit microbial activity as it is required for the synthesis of genetic and cellular components, metabolism and energy transfer. Little is known about how P...
Availability of phosphorus (P) can directly and/or indirectly affect nitrogen (N) retention and loss from soil by stimulating microbial and plant root activities. However, it is not clear how P availability and plant presence interact on nitrous oxide (N 2 O) emission and nitrate (NO 3⁻ ) leaching in soil. A mesocosm experiment was conducted to inv...

Soil microbes are frequently limited by carbon (C), but also have a high phosphorus (P) requirement. Little is known about the effect of P availability relative to the availability of C on soil microbial activity. In two separate experiments, we assessed the effect of P addition (20 mg P kg⁻¹ soil) with and without glucose addition (500 mg C kg⁻¹ s...
Effects of phosphorus (P) availability on nitrogen (N) loss through microbial nitrification and denitrification processes remain poorly understood. We conducted an incubation experiment to study the responses of N2O production after P (0 and 3 mg P kg− 1 soil) addition with and without NH4⁺ or NO3⁻ (0 and 15 mg N kg− 1 soil) in a high P-fixing gras...


Question (1)
Gibbs free energy of glucose is -686 kcal/mol, cellobiose is -1355 kcal/mol. I need to know this energy values for oxalic acid and phenol in kcal/mol. Any reliable source?
