I'm not going to post all my soil test results and ask for interpretation. however, I do have some specific questions...

pH: In one area, it is 5.1. What is my target range? The report suggested 1000 lbs of limestone per 1000 sq. ft. (but it was noted that a maximum of 75 may be applied per 6-month period. Also, some areas are 5.9. Is that ok?

One main area has high Phosphorus level (75ppm). If I were to apply a standard starter fertilizer to this area, would I make the level too high? If so, what sort of starter fertilizer could I use in this area?

All of my soil is sandy loam.

Organic matter is medium or medium high in the entire yard.

The patch where the lawn is yellow has the following results while the surrounding non-yellow area has bracketed results: pH 5.3 [5.6], nitrate nitrogen 5ppm [5ppm], Phosporus 38ppm [25ppm], Potassium 180ppm [180ppm], Calcium 500ppm [900ppm], magnesium 50ppm [50ppm]. How likely is it that calcium deficiency is the reason the grass is yellow?

Thanks.
