How do you guys handle weeds on the track?
What's a "normal" routine for working on your track?
Any prep or applications ever?
How do you keep dust conditions down?
The fellow who ran the backyard track we ran . Seems he disced it the watered and rolled with a small pickup with slicks . Saw dust , laundry soap are some things I've heard for dust .
Laundry soap will work well (and won't cause all the rust that calcium does.) A lawn sprinkler system makes things easier for weekly watering and not consume so much of your time.
As far as weed control -- Fill the tank in your kart an extra time and run more than one line.
Otherwise you'll need to keep cutting it up or spray it (not what I'd want to race in.)
