Kon-Tiki 'Essential' (KTE) latest system

Here's the latest system I've designed for the KTE. Updates will be made as new intel is discovered. So, here goes.

1- Forestry waste (Biomass) harvested,  dried and processed - ready to burn!

2-Kindling ready to light

3-Kindling lit

4-A 10cm bed of hot coals produced

5-Time to start layering the feedstock:

First layer. Add the next layer (and following layers) once the top of the feedstock starts to ash.

Halfway through the burn (after multiple layers)

6-Finishing the burn. Add some smaller feedstock then wait until the flame has completely died down before quenching. Alternatively, add a cap of large diameter feedstock on top of the final layer, wait until the flame has almost completely died down, then quench. The large diameter cap can then be fished out and put aside for finishing off the next burn.

 

7-Kiln quenched with a hose (could use a 20L stainless bucket with IBC too). Lots of steam produced. Result = biochar with variable degrees of steam activation for high surface area

8-pH adjustment. For alkaline Biochar do nothing. If neutral Biochar needed - with a calibrated pH meter, add a few small dashes of 'food grade' Phosphoric acid to the Biochar in water and stir with a star picket/stick. Recheck - should be a few tenths below 7 (or lower if acidic Biochar needed). Leave for 24 hours. Recheck and adjust if necessary

9-Some excess smoke water bucketed out (20L ss bucket with top coarse woven 1.6mm, 5mm aperture stainless mesh filter) into an IBC. Smoke water can then be used for seedling raising

10-Kiln tipped over 2 front legs for emptying the biochar

11-Biochar transferred to site of application eg.swales, Zai pits, fabric pots, raised beds etc.

12-Biochar milling
A sledgehammer for vertical pounding of a thin layer of Biochar on a 1.6mm HW350 panel (or any flat steel panel/plate)

13-Biochar Inoculation (experimental)
Liquid sea kelp (5L), microbes (3L, vermiculture extract) & NPK (2L, vermiculture extract) added to 80L of milled Biochar in each inoculater. Left for 48h to provide enough time for the microbes to move into their new high rise housing residence (on the nanoscale).

14-Permafert midden (experimental)
Inoculated Biochar: poultry manure, straw Lucerne, compost: local soil (40:40:20) = Permafert
Turn for a week

15-Permafert applied in swales

16-Direct seeding or seedlings planted in swales

17-Swales mulched around seedlings

18-Harvest the produce!
