Soil analysis
Hi guys, new guy here to organic lawn care & had my soil tested by West Virginia University soil testing lab. The soil PH was 6.8 which is fine but phosphate was very high (230), potash was very high (575), calcium very high (4397), and Magnesium was very high (792). Nitrogen was a little low. I haven't fertilized or limed in two years-what's up with my soil?

I don't know what SOM means. Lawn was getting a little bare & weedy. After soil test I put down a lot of soybean meal and sprayed with molasses and it's looking a lot thicker and is a very dark green. I have a lot of red thread in my lawn.

Soil Organic Matter(SOM) improves the soil's tilth and used to be called 'humus'... soybean meal should help to build that up...
Another strategy is to get some stuff already broken down into plant nutriment, in the form of compost... Standing water or even water that stands too long, is in general, not a good thing for the grass... it does however support a foot hold for various fungal infections... getting the water quickly into a deep rootzone is best case scenario, then the surface can dry thoroughly between waterings... It has been noted in other reputable organic sites that cornmeal helps with many fungal issues as well... whether it works on Red Thread in your lawn remains to be seen...

First good for you for doing the soil test. Is there a concern that is happening that is of concern?
I would feed Nitrogen only for a while for sure but aeration and top dressing with compost is a good idea.

The soil depth was 3 inches per their instructions. After this I sprayed molasses/water mixture and spread approx 40/lbs soybean meal per 1000 ft and my grass is growing like crazy. It is a deep dark green and very lush. I raked the bare & weedy patches and added perennial rye (yard is mainly fescue) & it has taken off as well. I think I just need nitrogen...?

Soybean meal seems to be all the N you need, if it has grown as you've described...

Red thread is not common in the fall. Nitrogen usually reduces red thread disease. Red thread is a serious problem on perennial ryegrass. Shop around--be sure to get a premium disease-resistant perennial rye--especially look for one that claims to be red thread resistant.
At any rate try to get a ryegrass type that is one of the top ten in the NTEP trial in your state.

I suspect the cec is high....holding the nutrients
I agree the p2o5 is twice as high as needed! I suspect when the property was limed, they generally used dolomitic Again, what was the cec?
