sodium

I received an interesting question about some soil test results. Hey Micah, I’m just looking at the soil test results again … is there anything to worry about regarding sodium (Na) being higher than potassium (K)?

The short answer is no, so long as sufficient potassium (K) is present in the soil. Cisar et al. looked at Tifway bermudagrass performance when the soil contained high amounts of sodium (Na).

Sand rootzones are common the world over for golf course putting greens. Many athletic fields are also built with a sand rootzone, and in Asia, many of the tees, fairways, and even roughs are grown in a sand rootzone.
