When worms eat compost and soil, the latter become five times richer than the medium worms originally ingest. The casting or excrement of these worms therefore can be used as an effective natural fertilizer for growing plants with the amount of oxygen they contain. Another good natural fertilizer is bat guano, considered by most information on natural fertilizer as one of the oldest fertilizers known to humans. Legends and other information on natural fertilizers say that bat guano was so important to the Inca civilization in South America that the penalty for harming bats was death. The composting process of bat guano starts with the fruits that are eaten by insects which are in turn eaten by bats. Droppings of these bats fall to the floor of the cave where millions of guano beetles and beneficial decomposing microbes thrive. This complicated process is what rids the guano of any toxins and dangerous pathogens, making them a healthy natural fertilizer for plants.
