Hello. I appreciate your help in interpreting my soil tests. Last June, the leaves on two of my mature tart cherry trees began to yellow and the fruit stopped developing. The trees were bare of all fruit and leaves by late summer and neither tree survived the winter. Another tart cherry tree in the same area, as well as three peach trees, did not show any of these symptoms. The cherry tree yielded an abundance of fruit but the peach trees produced minimal fruit. All of the trees were planted in 2018 and spaced 15-20' from each other. I received the soil test results from this area but am not sure how to proceed. The test results recommend adding only a very small amount of nitrogen (.07 lbs./100 sq.ft.) however I am unsure of the best way to add such a small amount. Should I apply chelated iron? I believe the micronutrients (iron, zinc, manganese and copper) are OK. I also have a question about the soil test results for my blueberries. The test results show low nitrogen and potassium but very high phosphorus. The recommended amount of 1-0-1 fertilizer is .2 lbs./100 sq. ft. which again is a very small amount and I am not sure the best way to add the N and K. The pH also reads low. When I established the blueberry patch in 2022 the pH of the soil was 6.2, which I reduced using elemental sulfur before planting the bushes. The last time I added any elemental sulfur was in the fall of 2024. The pH measured 4.5 in April 2025 using a digital meter. I know these meters are not always accurate, which is why sent in a soil test. The blueberry patch is mulched with pine bark, however I am wondering if adding additional pine straw around the bushes would be helpful to increase the organic matter (i.e. nitrogen). Additionally, I have been applying a 4-3-6 fertilizer to the bushes each spring but am unsure if I should do that this year as the phosphorus reading is high. Also, I do not have my organic certification, however I do follow organic practices when selecting products to apply to my fruits whenever it is possible. Thank you again for your help with this!
