Earthworms’ castings have unique characteristics that make them an
absolutely ideal plant food. In soil, they holdwater and release
nutrients in a form well-suited to plants. They are a concentrated
fertilizer that is most efficiently used as a portion of a planting
mix, but still won’t “burn” plants if applied more heavily. Laboratory
trials show that even 10% vermicompost in potting mix improves
germination rates, plant growth, appearance and fruiting. Castings also
contain plant growth hormones that provide a strong “kick” to plants.
Castings also deliver beneficial microorganisms to the soil in huge
numbers, and can thus impart some amount of disease resistance to
plants, especially when worked into soil at the level of the root zone
before planting.
What’s more, research has shown that the vermicomposting process can
reduce, and in certain tests, eliminate pathogens. Some farmers also
know that worm castings can transmit disease resistance to animals.
Chickens that scratch in worm beds, for example, eating worms and
castings, are more resistant to salmonella. We definitely need and look
forward to future research in this area.
