Howdy,

Is there a reasonable way to get accurate soil testing done?

Here's why I ask:

First, my local cooperative extension does testing, but, to
my amazement, none of there available tests (and they have
many) includes an assessment of nitrogen.

Next, I own a soil test kit, but discovered that it showed
nitrogen depletion even when testing a highly concentrated
solution of nitrogen fertilizer in water. When I found that,
I called the manufacturer and was told that it may have
expired. I asked where in the detailed instructions there
was information about expiration, but of course, there was
no such.

In any case, what's the solution? I would welcome any
specific suggestions.

Sincere thanks,
