I would never think, before now, to look for those things. I have just been buying reputable names. Those being EB Stone and Whitney Farms but now I wonder about some off local brand stuff that I have bought. I would think to get soil tested would be rather expensive and if that label is saying it has that they very well could be minimizing the amounts when those amounts are higher, yes?pepperhead212 wrote: ↑Sun Apr 02, 2023 5:31 pmI don't like those amounts at the bottom of lead, cadmium, and mercury. I have never seen those listed in anything I have looked at, even in trace amounts.
I think it is probably a better fertilizer because it actually makes the effort to report not just the good stuff but also the contaminants.
That does not happen very often. It is actually hard to find good analyses on organic fertilizers. Only a few companies do an analysis of the nutrients. Most just list the ingredients. Bone meal for instance rarely lists the amount of lead in it, and it does contain trace amounts of lead and other heavy metals. Not just in bone but in other parts of the animal. The levels are usually very low and because of that, the producer may not be required to report it.
