How's a good way to break up hard soil? Since it's all level, my
first thought is to soak it good for a couple of days. I wonder if
renting an aerator might also be good.

If your soil is like mine, there's a very narrow range of moisure
levels at which it's workable. I understand local farmers refer to it
as "36 hour soil", which is the schedule window for plowing.

Too wet and it's like warm tar, too dry and it's extremely hard. In
the middle, it's rather crumbly. I'd soak a patch and poke it each
day after. _Maybe_ you'll find a day when it's workable.

Hereabouts this is called "Sunday soil", too wet to work on Saturday and too
dry by Monday. The problem with working it on Sunday is that it will always
stay the same, you haven't addressed the problem of why it is so hard on
Monday.


Appreciate all the good info. For breaking up the soil, what about
adding a weak solution of detergent as a wetting agent in one of
these hose attachments?

When you sprinkle just a small amount of water, does it soak in or bead
up? If it beads up, then yes you need a wetting agent. However,
detergent or soap are alkaline, which can further harden the soil
structure; so make it very weak. Use it on the gypsum. Trying to wet
the soil before applying gypsum will merely waste water.

I have been soaking the yard once a month for about 30 minutes. Mostly it stays on the surface but soaks in after an hour or so.


Then use a minor amount of liquid soap or detergent in the water AFTER
you apply gypsum. A 30 minute soak right now is excessive. It can
result in wasteful runoff.

A 30 minute soak right after applying gypsum will wash away the gypsum.
The initial wetting down should be less than a 5 minute sprinkle, just
enough to make the gypsum damp. The next day, a 5-10 minute sprinkle
will start the gypsum dissolving; do not sprinkle long enough to puddle
or start rinsing the gypsum away. (Sprinkling instead of flooding will
hasten the dissolving of the gypsum because of the force of the water
landing on it.) Then every third day, repeat the dissolving sprinkle.


Thanks. To be clear, When I said soaking for 30 minutes, it does not run off. The yard is level and all of it soaks into the ground.
