Loading ...symptoms in young trees versus mature trees in the Sackville, Nova Scotia, images since I am not familiar with conditions on the ground there.
My only comment is that I do not get up tight about aluminum in the forest environment. After oxygen and silicon, aluminum is the third most abundant element in the earth’s crust, and aluminum is the most abundant metallic element (see Abstract and first couple of paragraphs in link below). Aluminum becomes available to plants only when soil pH drops below 5.5 (that is, only when soils are acidic, as they tend to be under most forest vegetation). Plants have had geologically long periods of time to adapt to various levels of available aluminum in the forest soil environment. I remain to be convinced that the alleged aluminum coating on the bark of trees shown in the Sackville videos has anything to do with the present condition of the forests shown in the videos.
