High Potassium Levels
I have a ornamental border with trees, shrubs, grasses, bulbs etc. that was planted last year. The area used to have a concrete pad about 3 inches thick. The concrete was removed and soil amended with 6 inches compost along with cottonseed meal, bone meal, and kelp at the recommended amounts. The ph was tested and lime was added. Fast forward to this year and my plants are displaying signs of micronutrient deficiencies so I ordered a complete soil test. Micronutrient levels came back as normal with the ph at 6.7. The phosphorus tested at 92ppm with the potassium at 630 ppm, very high on phosphorus and off the charts high on potassium. After doing some research I found the high potassium levels can effect the plants ability to use micro nutrients and that is probably the reason the plants are showing those symptoms. What I haven't been able to find is a solution to the problem. Does anyone have any suggestions?
