First I would have a pot of soil and a carrot (without fertilizer) then a pot of soli ,with fertilizer and a carrot. Then I would watch them for the same amount of time and identify weather the soil impacted the decomposition of the carrot and repeat this twice.
Same size pots
Same size carrots
Same soil
Same growth area
