In our area, the key nutrients for almonds that can be limiting factors of production are Nitrogen (N), Potassium (K), Boron (B) and Zinc (Zn).
Good new is that, all of our nutrients fall within acceptable ranges except for potassium.
University of California recommended levels are as follows and the results of the two samples at Carpenter are as follows:

University of California recommended levels are as follows and the results of the two samples at Carpenter are as follows:
N -- 2.72 and 2.58% (Recommended N 2.2 - 2.5% )
K -- 1.26 and 1.29% (Recommended K 1.4%)
K -- 1.26 and 1.29% (Recommended K 1.4%)
B -- 30 and 32 ppm (Recommended 30-65 ppm)
Zn -- 30 and 30 ppm (Recommended Zb >15 ppm)
Not-so-good news is that the best producing orchards have levels of potassium well above the recommended level of 1.4%. And potash is not cheap!
