Hi Marie,
Thanks, but still not a lot wiser.

Richard M. Watkin,
And you never will be when talking to one who chooses to be deaf, blind,
and dumb.

You probably have seen the reference to greensand in Wikipedia, so let
me describe another thought. One pound of iron (shavings would be best
but use what you can get) in a plastic bucket, pour one can of cheap
soft drink over it and wait 24 hr.. If iron remains, repeat soft drink
addition. When iron is dissolved, it will cover 100 sq. ft.


Why go to all that trouble (to make ferrous phosphate/carbonate/citrate)
when ferrous sulphate (copperas) is so cheap?

If you have iron filings, just sprinkle them around the garden.

A pound of iron should cover a lot more than 100 ft^2, but you're also
not going to dissolve it that easily. (Me thinks you are just pulling
this out of a dark place)

I have been in error before, but I don't baffle gab. Now what lead you
to your egregiously erroneous conclusion?

ferrous sulfate --- FeSO4·7H2O (most common)


at. wt.
Fe = 55.845
S = 32
O = 16

SO4 = 96

H2O = 18

FeSO4·7H2O = 278

Fe / FeSO4·7H2O = .2 = 20%

----------------
Greensand 17% iron: 40 lb bag good for 700 sq. ft.

1 - 40 lb bag = 6.8 lb iron

6.8 lb iron / 700 sq. ft. = 0.00971429 lb / 1 sq. ft.

0.971429 lb / 100 sq. ft.

You can do arithmetic, can't you Bob?
