    I received the results of a soil sample I did for a client and the Magnesium level is at 422. What, if anything should be done to correct this?

    My reference material tells me that 20 to 40 lbs./ acre is needed for turf growth. Reference also indicates that anywhere from 100 to 1000 lbs./ acre are not uncommon readings. Use of dolomitic limestone increases the magnesium level. I looked at some of our soil test reports, but we did not request a check of the magnesium in any of them. I hope I'm not way off base with this information, county extension agent should be able to provide you with more useful info.
  3. post the complete soil test report, make sure you include base saturations!

    what was the recommendations on the soil test report?
