If you burn plants in the natural manner when the ALL CO2 will be used by

some percent of CO2 will be used by plants (because "the lack of one element

decline in global sink" SO2 and fly ash are nutrient for plants.

I don't think plants are involved in the decline in global sink,
it is mostly the ocean that is getting more concentrated CO2 and
resists absorbtion of more.
And deforestation is another loss of sink, there are less
plants in those areas. But with increased CO2, all plants
should grow faster or bigger or something better.

I am not sure sulphur is needed for plants, but it may
affect solar absorption in the atmosphere and may affect the
precipitation of clouds into rain.

Most plant burning is done in the bellies of animals,
which may do a very good job of using all nutrients present.
