Opened the cores of 30+ year old trees
« on: February 18, 2015, 05:05 AM »
Well, we finally got around to opening the cores of a few 30+ year old trees.

What was seen was simply, the crushed red brick  which is factory fired and is essentially a matured earthenware clay [ 980 to 1020 deg.C melts at around 1180 deg.C ] it's still porous.
Remains in it's shape, and only the pieces that were fractured, but holding together after sifting, broke into smaller pieces.
Otherwise no decay, but that was expected since this clay can remain in the soil of old Amerindian sites, and even with the Amerindian lower faster firing technique, remains as pot, saucers and so on.
[ I have been to various digs around the island.]

The builder's gravel, silica based, but a fused together material, not formed by melting and maybe slightly porous, remains unchanged.

The compost, has gone past the stage of reforming into rounded shapes [ humus ?] and very little remains as fine partilces.

Roots are still active, and there were fine dead ones, plus holes with pill bug traces of mining.

Essentially, as was theorised or expected, the inorganic remains, and fresh organic material filters down and then out as fine material. No clogging of drainage holes has ever been seen.

No large roots / no taproot formation was observed.

All trees were given fresh soil mix, and a weeks rest in bright light/dappled sunlight, and are back in the full sun.

We used a lower organic %, and are looking at beginning feeding through composted soyabean meal.

Last year we used compost on certain trees, to observe the speed of growth. It was slow, to the point being a little worrisome.

What we have discovered is that for -us - we may just be able to grow trees in only builder's gravel and % of compost to handle the level of moisture in the soil.
The Chlorophora t. in the 3 mm glass beads and some compost is doing very well.

For us, the real factor is the composted and aged material, which we believe, will control moisture levels when used in small quantities, plus ability to hold artificial fertiliser applications [ if needed ].
Tests on Ficus p. shows, much finer growth, much easier to control the training. Especially in 1" deep pots.
It maybe that if our trees grow much faster than say Northern trees, they need to be more controlled in the branchlet/fine leaf stage.

Last tree on the list is the large Tamarind, but that won't happen until around April.
J.B.Pines will be done in 2017.
Good Day
