I was told I could get rid of old trees stumps in my yard by boring holes
vertically through the stump and filling them with acid. I tried conc. HCl
and it didn't do much to the stump. Any suggestions on what would work?

Pack high nitrogen fertilizer into the holes and wait a year for
fungal degradation. Nitric acid is much faster, but more hazardous.
White rot fungus will do nicely, as will termites.

A commercial product for this uses sodium nitrate. After waiting the year or
so, the stump can be burned. I suppose it can be done in a way that does not
burn down anything important.

I think the answer to your problem lies, not in Chemistry, but in Physics.

Hire a stump grinder.

I have seen saltpeter used this way. The stump degrades at a faster rate
when nitrate is present as it provides a more balanced diet for compost
microorganisms (Carbon/Nitrogen ratio). As a side effect adding the
oxygen makes it burn well without air so a fire started on a treated
stump will burn down into the ground and eliminate the roots.

In the UK there is a commercial product for this purpose - it is
sulfamic acid. And it works !

The other replies included waiting a year or so. If you fill your
stump with picric acid your stump can be gone in fractions of a
second. It is an explosive :). Other explosives may be more suitable
but you asked for an acid ...

Thank you for the recommendations. I have many more stumps to remove so I
will try using high nitrate fertilizer, as well as nitric, sulfamic and
lactic acids. Explosives will not be considered.

The most effective method so far has been to bore holes vertically through
the stump and fill the holes with diesel fuel. The diesel fuel is then lit
using a bit of gasoline and a lighter to get it to ignite. It took 5 such
treatments to burn out the stump.

Chop holes and plant with bergamot, aka bee balm. Let the plant's roots
chew through the stump while making your local hummingbird population
insanely happy.

A similar treatment of the problem consists of placing a steel
drum, open on both ends, over said stump. Pour in charcoal. Make your own
BBQ while toasting your problems.

a syrup of sodium chlorate and icing sugar dissolved in a small amount water
and fed into the stump for a week or so, can then be ignited when dry. It
burns slowly but will eventually remove any evidence of the tree stump and -
to the extent that the solution gets into the root system - they will burn
too.

My two cents worth: try hydrogen peroxide

I used to use it, as a mineral exploration field technician to remove
organics from sand and soil samples.

Hi,

If nitrate can accelerate the action of decomposing fungi, why not use urine as a natural source of nitrogen?

Urine contains urea that decomposes in ammonia.

And the ammonia can be converted into nitrate by nitrifying (aerobic) bacteria.

The nitrate will then be used by the fungi, decomposing the wood pulp and forming an important fertilizer.

A layer of feces would also give bacteria.

As long as you are prepared to wait a *very* long time or spend more on
the chemicals than you would have done on the stump grinder.

For a modest sized tree 8" diameter trunk nitrate based rot encourager
and a trace of copper to inhibit the woods antifungal enzymes about a
decade got one of my dead apple tree roots to a point where it could be
snapped out of the ground with a scaffold pole and fulcrum. It had some
spectacular chicken-in-the-woods fruiting bodies along the way.

Saturating it with potassium nitrate and the setting light one very dry
summer was my plan so that it would smoulder away underground but in the
UK the summers are never dry enough and the ground is always very damp.

I doubt it would have lasted long against a 45 drum of brown fuming
nitric acid but that would have been serious overkill.

This will depend on the humidity (more moisture faster), the temperature (warmer faster) and the availability of oxygen (more oxygen faster).

And also the contact area. If the material is fragmented into smaller pieces the contact area for fungus growth will be larger.
