High soil pH & salts #941173

Trying to determine a course of action to correct the soil in a berm. I have a soil test report from CSU. The soil test “High to Very High” in nearly every category. Very concerning pH of 8.9 and soluble salt levels of 5.6 mmho/cm. CSU commented that salts should be below 0.8 mmho/cm. Could you recommend a possible solution and how long that might take? This soil for the berm was put in two years ago and barely anything will grow in it. I could forward the full report if that would be helpful.

Hi April,
How did you collect the soil test? Did you pull several samples throughout the berm, mix them together, and then pull one sample?
Can you email me the results? My email is: <personal data hidden>
