A well fitting P2 or N95 with an outlet valve is great if you keep material disturbance at an absolute minimum...
If there's considerable particulate in the air I would not recommend being in that environment for very long at all.
Otherwise, with a good mask you should be okay.
And remember to dust off your shoes and pants as you leave with you mask still on. Wet grass works great!
