Just wondering if anyone knows at what point the soil microorganisms start to decline from too high of salts. Im assuming they do but can't seem to find any info. Maybe the plant would be affected before the soil organisms

High salts are problematic to both plants and microorganisms, partially due to the fact that excessive levels of sodium and chloride displace other essential minerals for microorganism and plant growth- calcium, magnesium, potassium and other micronutrients.

Im not sure there's a magic number or a testable level at which you can say salts are having a negative effect. If you know you have excessive salt/sodium levels, flushing the soil with non-salted water may be the best strategy, followed by a soil test to then restore fertility
