im a pyrotechnics enthusiast. i make fireworks, and thought of making eco fireworks.

most firecrakcer use a composition of KClO3 and Al, this is hardly beneficial, but there is a flash powder i use to use that was:
KNO3
S
Al

both sulphur and potassium nitrate are know fertilizers for plants. so i was wondering, if i was in an area with little vegetation, then set off a few fireworks, making a blast of potassium and sulphur compounds in the nearby soil, then planted seeds. would these plants grow better?

or would the fireworks even act as a fertilizer in the first place.

just some weird though that came into my mind
