Organic lawn care

[ds2]

I was wanting some help on what organic products to use on my lawn. I live in central Texas and have st augustine grass. Had a soil test done,

potassium was high
phosphorous was really low
soluble salts were a little high
need to improve drainage.

Had the yard core aerated twice already, one month apart. Ive always used chemical products, wanting to go organic, just need some guidance getting started.

Thanks

Looks like your salt and drainage problems go together... High water table? Lots of long lasting puddles after a shower? are you irrigating?
Jab a spade into the lawn, open it up and get a good look at the type of soil your dealing with, and whether it changes to a different layer...

Start with some compost, Milorganite, Mulch mowing and possibly some 'salt free' molasses will be helpful...
