Can anyone tell me if this cactus is rooted and what can i do to keep it alive?

No roots. Why does it look wet?

It had stuff all over it

What kind of stuff? Sticky stuff? Did you try to wash it off?

Dirt. i kicked it working in the yard. Do you know if i could save it

There are no roots. Can you describe the dark spots around the stem. Is the stem firm or mushy. Look into propagation of cactus. I am sure it can be saved, but I am no expert with cactus. I do know you have no roots. Until you learn some answers don't stick it in wet mediums, you are safer to keep it dry than damp. And that is the extent of my knowledge, hope someone here will come and point you in the right direction.

Thanks for the info. No its not mushy. I knocked it of a bigger cactus while working by mistake

It can probably be saved. You will want to keep it in a warm dry place - let the base completely dry out - at least 3 days or so, after that check how the base looks and feels - if it is dry and hard then it is probably OK to stick in some soil. If not leave it to dry longer.
Get some really well draining soil put the cactus into the soil maybe up to were the cactus goes from green to yellow or slightly below that. The soil can be a little moist but should not be wet. Do not water for at least a week and then only very sparingly - you do not want that soil to be wet for very long. It takes a while for new roots to develop and until then watering is not really doing anything for the cactus except increasing the chance that it will develop rot and die.
I usually wait with watering until I see new growth, but you can also check occasionally by slightly pulling on the cactus to see if there is any resistance - if there is it has new roots, if not then there will probably not yet much down there.
Keep the cactus warm and in bright light, but not direct sunlight until you see new growth, then you can start exposing it to direct sunlight.

I root a lot of cacti that come off bigger plants and while not 100% successful it is not that far off. As long as the plant does not have rot and the break is dry and calloused over before planting and you are really careful with the water, you have a good shot at success.

Good luck!

Trim any damaged material from the bottom with clean cuts from a very sharp knife, and place it on its side in warm shade with plenty of air circulation for about a week so the cut can "callus" or heal. Fill a small container with a mix of 75% perlite and 25% potting soil. Dampen the mix slightly so that it doesn't separate as you mix it. It's better if the container is taller than it is wide. Place the cactus just deep enough so that it is stable, and put the container in a sunny (but not hot) windowsill. The soil will probably have enough moisture to last until the plant produces roots, so wait until you see new growth before watering. When it roots, you'll see bright new growth in the center. You can set it outside on sunny days after that, but I'd wait until spring before feeding it or leaving it outside.

Most people can't help themselves and will be tempted to occasionally lift the plant and look for roots. If you put about an inch of perlite on top of the soil mix and set the cutting into that, you will be able to gently lift the plant every couple of weeks to check. The perlite will make it easy to remove and replace the cutting.

Edit: It appears that a little cross-posting happened...

Ill give it a shot. Thanks

Agree with everyone, no roots. But got to let it dry and callus as suggested already. Unfortunately Fall to winter is slow down time now, so be very, very patient with it. Keep it warm and dry. Then put in a dry media, and let it just stay there by a bright and warm spot on your sunniest window. Better renewed vigor in mid Spring. As long as nothing feels mushy soft below there is hope.
