The soil sample has to be a representative of the soil. I think you could've take sample from 2", 3", 4", 6", a fistful of each,
mix them all together well and then have made a sample out of that
for your test.
Normally top several inches of soil is poor in nutrients, especially nitrogen.
The reason is that nitrogen is water soluable and will sink down gradually.
That would be directly depend on the amount of snow and rain.
And for that reason it is a good practice not to fertilize until close to planting time.
Also that is why it make sense to turn over your garden in the spring
a good depth of about a shovel height.

and plant a cover crop to till in before growing to add more nitrogen!

Great ideas. I took different depth dirt sample & did the other 3.
Nitrogen(blue cap), Phosphorus(purple cap), & Potash (orange cap).

Concerned about them. Nitrogen and Phosphrus seems low. Not sure about Potash..actually lighting up as I type. Seems like thats low too...

ahhh what to do now what to do.
