Easiest and most efficient way to get worm castings is to get a lot of worms to take up residence in your garden. Add cottonseed meal to your soil when you prepare it for each season and if there are any worms in the area they will take up residence there. Another helpful thing is to mulch heavily as the worms like the soil to be more moist and cool. Heavy use of dry chemical fertilizers will run them off. I guess they are just too caustic for the worms.
