if you put to much wont that kill the dirt your working with and then salt will kick up and eat your bike =(
a better way would be mix some salt water (heat up water then add in salt and mix in really well so that it dissolves then feed it right on the weeds...
for the grass if its really really tall cut it down then ride over it a bunch and that will probably work much better
if the grass is that tall really stiff annoying shitty kind, go get a shovel or a grub hoe and beat the shit outa it =)
Salt will kill the grass but it will also poison the soil so nothing will grow there for a long time
what do you want to plant on or near your jumps or pump track? haha but yea it is kinda bad for the soil and people might be mad if they kick you off and try to develop it but whatever

ya this will be more effective, as the plants will absorb it
