I really need some info on this. What are the environmental implications of using cultivated ground up tobacco stalks/waste as mulch? Do the pesticides used on it during the growing season carry over and affect the soil...the vegetables...and ultimately, me? Should I be handling this ground up waste, or breathing its dust? I know it will make great mulch as far as organic matter is concerned, but I need to know the after effects. Anyone out there with info on this? Thank you!!!
