Compost tea to cure poor soil?
I am new to compost tea and have come across a decent brewer. I'm going to start offering applications but I want to offer my clientele something practical. According to what I have read compost tea will aerate and transform poor and compacted soil. Most every lawn in this area has poor soil with maybe 50% of actual grass. Most all soil here has a high clay percentage, is compacted, and is quite acidic. Phosphorous is also naturally deficient.
My question is this:
At what point is completely renovating the lawn more practical than a mixture of over seeding, selective weed control, and compost / compost tea applications? This is an art and a science so I know that the best I can get are tips / guidelines. I can surely post pictures and describe in more detail.
Thank you for your consideration,
