I tested a few places front and back and all were pretty much the same.
pH was 6.5-7.0 everywhere. Nitrogen was non-existent as I expected,
phosphorus was the good range. (Sorry I don't have the values here with
me right now.)
But potassium was way high off the scale. I checked again using half
the amount of soil, and still came out in the low end of the high range.
The only fertilizing I have done is once a year or less with 15-15-15
and a drop spreader.
What I'm wondering is where that high level could have come from? And
if this level is high enough to do damage? Have grass, avocado & lemon
tree in this area.
This was the best test kit I have ever used -- will post the info &
values I got later.
