Re: Is this high manganese?
I have seen this in German hay before, with even higher manganese. Around 600, after retest still above 500. Couldn't hurt to ask for a retest of the managnese before you start balancing to it, but working with 305 should be pretty do-able.
I've also had tests of Dutch grass that came in with around 200ppm manganese and about 100 iron.
The iron will fall below the 4 in the 4: 1: 3: 3 ratio but that is ok, certainly if you usually have high iron.

I'm wondering if I need to retest my hay. In your opinion, is 305mg manganese very high? Should I suspect surface contamination?
I was so happy when I saw the low iron (very rare here in our area, only 78mg), but then I saw the manganese. :/
