Clearly the use of vermicompost in field soil is much more complex, in terms of methods of application, location, and relation to the plant roots, seasonal effects, and residual effects, than its use in growing greenhouse crops. In the greenhouse, soils, amendments, growing conditions, and application methods are much more standardized. We still need to identify the lowest effective economical application rates for different crops, soils, and regions. It seems likely that aqueous vermicom- post extracts, or “teas,” will be much easier to use on field crops than solid vermi- composts. Teas can be applied as soil drenches at appropriate intervals in the life of the crop. For further information on the use of teas to improve crop germination, growth, and yields, see Chapter 15.
