Research has shown that earthworm excrement, also called castings or
vermicompost, improves the aeration, porosity, structure, drainage, and
moisture-holding capacity of soil.
Many studies prove that when compared to conventional composts, vermicompost
is less variable and much more stable. Mixing vermicompost into the planting
medium essentially eliminated the need for additional fertilizer in the
production of tomato plugs as one example.
Studies show that earthworm castings increase height, stem diameter, enhance
root growth, increase dry weight, and produce more flowers per plant than peat
moss.
Redworm castings are the richest and purest humus matter in the world. Humus
is believed to aid in the prevention of harmful plant pathogens, fungi,
nematodes and bacteria.
One pound of worms can convert one pound of pig manure into compost in 48
hours!
Worms consume three times their weight a week or more. Red wrigglers are very
active, reproduce quickly and consume their own body weight of waste every 24
hours. Therefore ten pounds of worms will eat ten pounds of waste in 24 hours!
Worm castings provide a rich source of a variety of essential plant
nutrients.
Microbial activity in worm castings is 10 to 20 times higher than in the soil
and organic matter that the worm ingests."
How to use worm castings:
When planting vegetable and annuals line the rows and holes with about two
inches of castings. About every eight weeks side dress the plants with one-half
cup of castings per plant or one cup per foot of row.
For perennials work one-half cup of castings into the soil in the spring,
middle of summer, and early fall.
For pots and hanging baskets add one-half inch castings to the top and water
in. Then reapply every eight weeks.
Roses appreciate four cups of castings per plant.
If starting a new lawn add 15 pounds of casting per 100 square feet when
sowing. Once established use seven pounds per 100 square feet.
