Earthworms belong to the soil community. The earth is their home, their source of food which is teeming with microbes.
Earthworms are organic gardeners and composters. They break down decomposing organic matter in soil and their castings (worm poop) contain five times the amount of nitrogen, seven times the phosphate and eleven times more potash than the regu- lar compost (sheep, steer, horse manure or house scrap materials) the worm consumed. This is the richest, all-organic plant food on the planet.
