What is a preferred analysis for the micronutrient Manganese....and...what product do you add if necessary. Mine is at4.5 ppm this year....last year it was 12.5. Mark

Mark,

Soil applied Manganese is quickly locked in our area.

I probably have some chelated Manganese here. I'll give you some. Foliar is the way due to our odd soils.

Steve...What is a good reading for Manganese(in ppm)? Does a deficiency affect fruit size? Mark

Over 10 ppm would be nice but some massive fruit have come out of soil that we would consider "way deficient". I have Andy Wolf's soil test spread sheet on the other computer. Manganese seems to be all over the board. Folks who need to use limestone to correct their pH always seem to have low MN but some of their fruit weights don't justify our concern.

You need Mn in the soil but as pointed out, it might not be available.

The best thing to do is a foliar test.
