    Thanks Jacobs,
    I will do a soil test, probably Ca is high (>80% CEC), Boron could be low (<0.7 ppm). I wrote those numbers on the base of other soil tests in my area.
    I would be interested in visual indicators (leaf, stem, flower) possibly describing low boron, low manganese, low phosphorous availability. Or weeds that can be indicators of such conditions.
