FeEDDHA is a ferric chelate which is generally regarded
as stable upto about pH 9. I have used it to correct
the iron deficiency chlorosis which develops in Erica
when grown on chalky soil.
FeEDDHA works when applied to the soil and foliage. However,
it does seem to become locked up in the soil over time.
FeEDDHA is often called 'Sequestrene'. It is also available
in the UK as 'LibFer SP'.
