This is a great article well worth some study.

this cycle is naturally regulated by the speed at which bacteria can change one compound into another, and by the amount of bacteria available in the soil.

The dawning of the Industrial Revolution heralded a major change that greatly affected the nitrogen balance. Large-scale burning of fossil fuels such as coal and oil released high levels of nitrogen oxides (including nitrous oxide or N2O) as fumes.
. . .
There are two main things that these nitrogen compounds affect: the environment and human health. When nitrous oxide (N2O) reaches the stratosphere it helps destroy the ozone layer, resulting in higher levels of UV radiation and increasing the risk of skin cancer and cataracts. Ironically, when N2O is nearer to the Earth’s surface it can actually make ozone, which can become smog on a still and sunny day.
. . .
But the problems extend further. The overuse of fertilisers on fields and of nitrogen compounds in animal feed leads to nitrogen leaching into streams and rivers.
. . .
Finally, nitrogen oxides contribute to global warming. Although the concentration of nitrous oxide in the atmosphere is considerably lower than that of carbon dioxide, the global warming potential of nitrous oxide is over 300 times greater.

So if tera preta or charcoal holds on to nitrogen in the soil ; what is the effect
