    Just talked to a customer that said he can not grow grass in his yard. He said that he has tried to several years now. He had the soil tested and thaey told him that the PH level in the soil was to hi. How do you change the PH level in the soil?

    If he did a soil test where he sent off for the results they will tell him what to do. Did he do one of those cheapo test it yourself tests?

    You need to send off another soil test instead of going by what he said. Charge him at least $20 for the test since you pay for the soil test and postage.

    I'd retest the soil as well, either Lesco or the co-operative extension office near you:dancing:

    Do another soil test and request base saturation of Calcium, Magnesium, Sodium and Potassium. This way you will know which minerial is causing the high ph and which ones you need to lower. If calcium levels are low, treat soil with calcium sulfate to help raise calcium levels and lower magnesium, sodium, and potassium levels. If magnesium is low, magnesium sulfate can be used. For high Sodium , use Potassium sufate. Potassium levels should always be higher than Sodium levels. When figureing how much sulfur to use, it takes 3 lbs of sulfate sulfur to equal 1 lb of elemental sulfur. Sulfur in your soil should be 50 ppm. After figureing how much sulfate you used you can substract that amount from the elemental sulfur required and then apply the remaining amount as elemental sulfur. Base saturation levels should be 68% calcium, 12% magnesium, 3.5% sodium and 6.5% potassium. Get these nutrients in these ranges and the grass will grow.
