did you read it all .....?it is a very long winded way to say this is what may happen,not that it will definitely happen.
just like they told us all fats are bad for us .they were wrong then and are probably wrong now.
one study does not make it so...
Now that's a solid arguement! Who's "they" and when did "they" ever say that all fats were bad (what about olive oil?). You do know what a strawman arguement is, don't you?
Actually, I did read it all and it's based off a C4 monocot that is known to be able to absorb non-anion/cation substances in small amounts. In a C3 dicot like pot, it is likely the case that the absorbtion rate of carbohydrates is going to be lower than 0.6%. There are other studies refered to at the end of the paper so this is not just one study.
I don't care if people put sugar in their soil but I would at least like the people interested in learning about plants to understand that this is a technique that has never been shown to have a positivie benefit for plants and can actually have a negative effect on their plants such as lowering the gaseous oxygen levels around the roots due to excessive bacterial action and potentially throwing off the osmotic balance in the roots making nutient uptake more difficult for the plant.
