Pecans Overcoming Zinc Deficiency Naturally

This picture (No.1) shows a tree that grew vigorously until it ran into Zinc deficient problems. Those include "die back" as can be seen by the dead twigs at the top of the tree. Bunching of leaves and very close inter nodal spaces and also browning of leaves making photosynthesis less.
The tree is in big trouble.
We take the shells from the previous harvest and put a heavy load on the drip zone or root area of the tree as you can see in the picture. The natural nutrients from this material is in a usable form for pecan tree absorption. It has been successfully absorbed by pecan trees before.
Nothing can be done about the damage already there.

This picture (No.2) shows a tree in the recovery stage. The dead twigs from the first phase of vigorous growth can be see directly above the stem.
The tree has had applications of shells in previous seasons and new growth without Zinc deficiency is seen on the left side.

This picture (No.3) shows the final stage of recovery. On the left side some browning and rosetting can still be seen, and on the right nuts can be seen amongst the healthy green leaves. Because the tree is beginning to bear a crop, the recovery will be dramatic from here on and in a few years no evidence of Zinc deficiency will be visible.

For me the interesting observation is that the recovery of the tree usually begins on the south-east side of the tree. This is the coolest side of the tree and the side with the slowest trans location of fluid and nutrients. The bark is thinnest on the south-east side of trees in the Southern Hemisphere. The converse applies to the Northern Hemisphere.

I think that good research results can come from the study of the relationships between phloem capacity or thickness, temperature and zinc trans location. Just maybe, a thick layer of white paint cooling the warmer (north north-west in Southern Hemisphere) side of the stem may slow the rate of nutrient trans location and give the cell development time to assimilate the required constituents for normal cell development.

Academics do not find funding for research that does not result in the use of synthetic products or petro-chemical by-products.
Organic farmers need to be observant. Chemical farmers just get the goo and spray it.
