I innoculate bio-char made from accacia thorn trees/branches & then use it incorporated into soil at +/- 10% of each prepared planting hole's volume (for open field crops a pick loosens the ground at each hole, the steel head is used to break apart the clods & then can mix in place any preparation want for planting into) .

(a) coconut water is collected from the green coconut for use; then the outer green layer is sliced off the coconut with a machete (ie: not used here) & the fresh husk is split in half; any coconut jelly "meat" is scooped out for eating - for those not in the tropics,but near a metropolitan supermarket look for refrigerated pre-peeled drinking coconuts (not the dry meat hard coconut)

(b) cracked pieces of bio-char that have previously been soaked in an indigenous microbe innoculate solution is set down to lay out inside the curved hollow of the split coconut

(c) the moist new coconut fibrous shell, with it's immersion innoculated bio-char, is placed on top of the soil under a tree's noon time shadow-line margin (ie: not laying up against the tree's trunk & yet not out fully exposed on the ground where the rain can pound down on it; you want to be under the tree canopy, but indirect sun during the day is fine)

(d) then it is all fully covered with well aged cow manure collected from milking cows (first break apart the manure clumps with a shovel or strike manure clods with pick-ax head so it can spread to cover your agricultural preparation better)

(e) leave the preparation in place for a minimum season of +/- 6 months before use with crops (uncured bio-char is capable of interfering with Nitrogen availability of field crops); the aged coconut is appropriate for use as a soil amendment & this "coir" can be chopped/sliced up with a machete (or shredded if taken out in the dry season); however, do not deliberately pulverize the inoculated bio-char (ie: use it in pieces that it was when you first set it out months earlier; if you really need small particles to work into your growing site then make the bio-char into that size of pieces before you start to culture everything together ); keeping the inoculated bio-char pieces'

end-product intact helps maintain the fragile fungii structures you desire to put to work in the soil, when you finally add it into your growing site
