Going green...

 My county extension office has recommended (based on a soil sample) a
15-0-15 for my St. Augustine lawn, and given me a list of organic soil
amendments (bloodmeal, bonemeal, etc). How do I know how much of each to
buy/ mix? Here’s what I’ve got:

Amendment                 Affect on pH       Major Nutrient supplied

Bloodmeal              Acid               12% Nitrogen
Bonemeal              Alkaline         22%Phosphorous
Fishmeal                  Acid               10% Nitrogen
Wood Ashes                Alkaline           4-10% Potassium
Peat                      Acid               1-3% Nitrogen
Mushroom Compost          Acid               2% Nitrogen
Seaweed                   -                  4 -10% Potassium
Biosolids (Milorganite)   -                  5% Nitrogen

My numbers:
pH was 5.7 (target 6.5)
phosphorus  15 ppm
potassium   37 ppm
magnesium   69 ppm
calcium     675 ppm


You may surmise (correctly) that I haven’t got a clue. Thanks in advance
for any help!!!!

The compounds listed are good for organic gardens, but for lawns just
buy 15-0-15 fertilizer.  You can lime now to correct the pH, but wait
until late spring to fertilize St. Augustine.  Your Extension agent
should have provided application rates with your soil report.

Thanks for the reply! Trying to get away from the yard service, for
obvious reasons. I did get application rates.. just didn't know what the
hell I was looking at. Thanks again!
