This would lead me to wonder whether there was not a lot of residual sugar in 
the charcoal from said syrup, which would definitely be a different thing 
than JUST charcoal. As we've read earlier in this discussion, the sugar promotes 
a massive, temporary bloom all all sorts of soil critters. This bloom and it's 
associated activities could well be responsible for using up easily available 
soil nutrients, making them less available to plants in an immediate sense. 
Then, when the sugar has been consumed, there is the die off of many of the 
extra critters and their decomposition releases all those nutrients again in a 
form readily available to the plants.
