http://youcancompost.com/Compost-Bins Upright compost bins, as opposed to Compost Tumblers, are the preference of many gardeners. These standing units reduce bending when adding materials and make great use of gravity to produce quick and nutrient-rich compost. Because the bottom of the bin on many models is open to the ground, earth worms and other beneficial microbes will enter the bin from the earth below.
