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
