I've never read this before, it was from a book I'm reading about someone who escaped from a prison camp in North Korea:

"and their apples come from an organic orchard where sugar, a rare and costly commodity in North Korea, is added to the soil for sweeter fruit."

That's news to me!

probably a fiction book, you would probably just attract ants.

That's not going to be absorbed through the tree and find it's way to the apples. What it will do is to add extra carbon, which helps the microbes which compete with the plants for nutrients. In fact, it's a silly but somewhat effective way to reduce weeds. And yes, it will attract ants, and probably squirrels and a lot of different bugs.

Heat and sun is what sweetens fruit.

Heat, sun, and genetics.

Sometimes you get better fruit if you starve the tree a bit

recent research into soil microbiology has presented some interesting concepts re making soil nutrients more readily available to the plants/trees.

there's a recent study out showing a significant increase in row crop production with the application of 3 lbs/acre of sugar to the fields, given in 3 each 1 lb/acre applications via fertigation. The study farm used white granulated sugar dissolved in water for their first trials, then switched to corn syrup as the sugar source for convenience. Improved crop production was noted over several years of such applications and the theory is that the microbiology makes the fertilizer and soil nutrients more available.

The point here is that sugar added to the soil is not directly taken in by the plants/trees, but may have a positive effect upon the nutrient intake of the plants/trees due to other soil factors. Hence, this could result in "sweeter" fruit from a healthier more vigorous tree.

At this time, the chemistry/biology behind such soil treatment is not fully known or understood. Some agronomists are heading down this path, some are against it. Time will tell.

I went to a talk about hardy citrus, and two of the things I learned were to only fertilize up to July, not after, and by withholding water I could force blooming.

I have done both of these things this year and my 2 citrus are thriving. I think I was killing them with kindness before.

3 pounds an ACRE? Hard to believe that's enough to d anything if you're talking sugar of "normal" concentration. If it's that cheap I guess that's not much to lose.

understand that you're not "feeding" the crop producing plants with the sugar ...

you are feeding the microflora/biology aspect of the soil to enhance the nutrient uptake by the crop plants.

while not a totally new outlook, it's only recently that pro agronomists have been researching this aspect of soil and plant production. There's still a lot to be learned as to why/how this is beneficial to the crops, but the initial studies of the last few years have been generally met with success.

My agronomist/compost tea supplier says that they've had mixed results with this application. When it works, it appears to work well.

Hard to believe 3lbs per acre can do anything when it takes 2,000 lbs ( one ton) of lime per acre to raise the ph by just .1 points
