I wonder if anyone has done any serious experimentation with worm castings in soil and seeding mixes? If so, would you post your findings? Thanks.

Some things that have been stated about the benefits of its use:

Suppress fungal diseases (phythium, fusarium, dollar spot, etc.)

Reduce algae in greenhouses, ponds & lagoons

No nitrogen run-off

May be applied to phosphate sensitive areas

Reduce irrigation cost up to 50%

Increases drought resistance

Reduce all chemical costs by 75% first year of 3 year program

No ground water contamination

Improve crumb structure of soil

Non-toxic - reduce liabilities for employees and clients when used professionally

Fast Facts:

Worm Castings contain 5-6 times the available nitrogen found in topsoil

Worm Castings contain 17 times the potash found in topsoil

Worm Castings contain 1.5 times the calcium found in topsoil
