Question

[Bob Wise]

To all,
	I'm looking for a standard procedure for testing the fertilizer
value of a soil supplement derived from treated sewage biosolids.  A local
sewerage district is considering processing and marketing their product.
One of the many questions they need to answer is what effect does it have
on plant growth.  Does anyone know of a standard set of conditions (plant
species, soil type, watering regime, etc) that is used for this type of
study?  I can come up with my own design, but I'd hate to reinvent the
wheel if I don't have to.

TIA

Bob
