The issue with injecting nitrogen in the soil isn't about the nitrogen's source, but it's impact on the carbon content of the soil. >There has been some research showing that these high nitrogen inputs are destroying the carbon in the soil. Because the microbes use up the extra nitrogen and then they really tear the carbon out, creating lots of CO2, rather than sequestering it in the soil. So there is evidence that excessive nitrogen actually causes more carbon to leave the system. Whereas we need more carbon in the soil rather than less.
