Can You Use Too Much Ironite?

This question materialized from a Dear Reader.

Yes.  You can use too much ironite.

While you're unlikely to burn the grass from the nitrogen levels, which are extremely low, Ironite is very rich in iron and other micronutrients.  The iron is also unlikely to cause issues, but may cause some interesting changes in your soil pH, so a soil test is recommended.

Overloading soils with micronutrients unless you know exactly what you require is never recommended.  While some are fairly harmless, others can cause issues up to and including the inability to grow any plant for a period of many years.

Here's the ace kicker.

"According to information provided by the Ironite Products Company and published by the Washington State Department of Agriculture, it contains 4380 parts per million arsenic and 2940 parts per million lead."

Even if it contained less than one percent of that, I'd avoid use on my lawn and gardens.
