The Coupling of the Carbon and Nitrogen Cycles in Agriculture: Crop Ecosystem Oxidative Ratio and the Effects of Fertilization on Biofuel Feedstock Quality
Agriculture significantly impacts the global carbon (C) and nitrogen (N) cycles through land use change, soil C loss, greenhouse gas emissions, and increased fixed-N availability. Agriculture occupies a third of the ...
Volatile cycling and the thermal evolution of planetary mantle
The thermal histories of terrestrial planets are investigated using two parameterized mantle convection models for either Earth like planets and planets with no active plate tectonics. Using parameterized models of mantle ...
The Effects of Land Use and Human Activities on Carbon Cycling in Texas Rivers
I investigated how land use and human activities affect the sources and cycling of carbon (C) in subtropical rivers. Annually rivers receive a large amount of terrestrial C, process a portion of this C and return it to the ...
