Soil analysis recommendations

We ran a soil sample on a clients lawn. Why is P so high? From the analysis, what does their lawn need?

Phosphorus is high because past fertilizers probably contained it...even though grass doesn't usually need much. No problem...just do not include phos in your fertilizer program.
Since potash is a bit on the low side. You should use something like 26-0-8, 24-0-11, or 28-0-7. A ratio of 4 to zero to 1 is about right. However, you should use a nitrogen that has about 50 percent of the nitrogen formulated as slow release nitrogen. This may be a bit hard to find as it is cheaper to use only 30 percent of the nitrogen as slow release.

Looks like a good winterizer is in order, so that takes care of the chemical side of your soil...

What is the physical side of your soil telling you???
