"The Myth of Nitrogen Fertilization for Soil Carbon Sequestration"
is published in the November/December 2007 issue of the Journal of
Environmental Quality.



Interesting. This is somewhat parallel to the view that much superphosphate
goes to waste as it is not necessarily useful for all the situations whee it
is used.

I wonder why they authors do not advance a mechanism for why excesive use of
nitrogenous fertiliser depletes organic carbon in soils.

My guess would be that the chemical fertilizers kill the microbial life
and that rain water and watering flush the nutrients away.
