I have a lawn I did a soil test on because it looks sick and will not thicken. The grass is tiff. The ph is 7.6 and the lab recommended Sulfur to lower the ph into the 6 range. The question I am having is the Sulfur concentration is already 148ppm which is very high considering optimal is 20-40. Is it just that the S is bound up in the soil and not being converted to sulfate and used or what do you think is going on? It seems adding more S would for sure put the S way off the chart. P and K are low which I will add a good fertilizer to up these. CEC was 14.8%. Boron and copper are low and iron is high which I am sure is bound up in the soil, everything else is normal. Thanks!
