Hello Michael,

It good to know that you are using plant tissue analysis to investigate 
the elemental content of crops. Are you finding the analytical results 
to be informative?

Are there any locations where plant and/or soil analyses have been used 
to compare control plots that have not been amended according to your 
recommendations with plots that have been amended according to your 
recommendations?... If not, have plant and/or soil analyses shown 
consistent changes over time when soils were amended according to your 
recommendations?

*****************************

There are many labs that perform elemental analysis of plant tissue for 
much less than $50/sample so you might want to shop around.
here is one example:
