Re: Ironite
just dug out 40# my bag of ironite. applied it 2 days ago over 3 patches.
it had been sitting in the basement since spring. note to buyers: if let
sit in humidity, it will cement together. dropped it on the floor a few
times to turn it back to granules before spreading. anyway, here's what
the bag reads:
Total nitrogen (N) ........1.00%
Calcium......................1.00%
Magnesium.................1.00%
Sulfur..........................5.00%
Cobalt.........................0.0005%
Iron.............................4.50%
Manganese..................0.05%
Molybdenum................0.0005%
Zinc.............................0.45%
Nitrogen is derived from Urea. Iron is derived from pyrite and iron
sulfate. Sulfur is derived from pyrite and sulfate. Other elements are
derived from sulfates.
Then there's a caution about how it will stain cement walkways.
It doesn't smell too good, so i'd assume there's some level of toxcisity to
the dust.
There's no mention of lead or aresenic content, but i'm willing to take my
chances. It seemed to work this year, so i'm using again for next season.
Seems to be one of the better micronutrient fertilizers, at least the only
one i've seen.
