Charcoal and Salicylic Acidⁱ
Nikolaus Foidl, Bolivia, February 6, 2008

Dear All , some photos.
First the difference between Charcoal and non Charcoal was nearly 60 cm in height, then after correcting soil minerals and applying Salicylic acid the difference vanished and the plants started really to grow.The maize started to get up to 5 cobs build on every shank in every axle. Could harvest now up to 4 fully developed cobs per plant in the no charcoal and in the charcoal plot. No measurable difference between the two areas.Will repeat those trials to get to the bottom of it.This time will mill and extract with different acids all minerals from the charcoal prior to the introduction to the soil to see if there is still some growth enhancing effect left in the first stage.( without adding salisylic acid.) Best regards Nikolaus
