The leaking soil nitrogen cycle and rising atmospheric N2O: Is there anything we can do to cap the well?
Rodney Venterea received a PhD in Soil Science from the department of Land, Air, and Water Resources (LAWR) at UC Davis in 2000. He was a post-doctoral research associate with the Institute of Ecosystem Studies until 2002, when he joined the USDA Agricultural Research Service (USDA-ARS), and department of Soil, Water and Climate at the University of Minnesota in St. Paul where he is currently a research soil scientist and adjunct faculty member. His main interests are measurement, mitigation, and modeling of soil greenhouse gas emissions and soil N cycling in agricultural and forest soils.

A cap on nitrogen emissions: a farmer's perspective
Mike is a beef farmer and a trustee of the Lake Taupo Protection Trust—a group involved in the implementation of the Lake Water Quality legislation (RPV. 5), which is one of the first mandatory non-point source trading programs in the world. The Trust is charged with removing 20% of the leached nitrogen from the Lake Taupo catchment by 2018 by changing farmland to lower leaching land.
