Soil Test results from Exstension- teach me about P
I am getting ready to prepare for new plantings of apples and blueberries. I sent samples from each of two planting sites to the U of Mn and got back the results.
I had expected that I would get a report back that showed I had average to good growing soil and that I would end up digging out and replacing the soil for the blueberries.
That seems to be what I got.
But I am really confused about the Phosphorous - The report shows it as Very High on the scale. I am curious as to
why it might be so high, and also what it means to me for my growing plans.
At least for the apple site I am pretty sure that the soil has been pretty ignored/undisturbed for decades. It is a grassy area near oak trees.
Also- does the organic matter tell me anything?
I am as much interested it learning about the measures as figuring out what they mean for me.
Organic matter: 3.5%
P: 36 ppm
K 110 ppm
Organic Matter 4.8%
P 45 ppm
