What is the PH naturally?
@Chuck is right about the molasses. Quantity is key though. He told me in another post 4-7 gallons of molasses per acre. I was not using that much. Well at once anyway. I spray a lot over time I guess. That idea of growing your own biological compost in the soil is basically like growing
Milorganite without the metal and other contaminants from the sewage. It is also the underpinning of
Terra Preta which literally grows in size over time because the the depth and volume of this activity. Wood chips are also adding to this carbon content like the Terra Preta idea, just slowly, like a forest litter works. And it looks like litter so tough to put on a lawn for aesthetic reasons.
One way to get there is
here. This company is an example of a good organically oriented lawn soil lineup, but they have garden uses too. They are too far away from you to make freight reasonable, but it is good to observe how they blend humic acids and soil conditioners with naturally fertilizing components. It is a leonardite based humic line should you need to look into the sources which I believe are an Arizona mine. You may care to order dry powdered humic acid from other sources and mix it yourself. Fulvic acids I believe, still comes as a liquid.
You will want to use some protein to start though. The bugs need amino acids from the protein. It is the amino acids which make up proteins that are used to make the bodies of the soil biology. And chemical fertilizers (salts) will kill them off and starve them off. Protein is usually a pretty big component of organic based fertilizer like blood meal. You can guess the protein content as a facto of x5 or x6 the N stated on the bag if it is organic. I use soybean meal since it is roughly 48% protein for this reason and the soil bio feeds on it as well as being a tightwad. The N is roughly a division of 5.25 into that 48% for soybean.
I have heavy red clay here in Alabama and molassess, moisture, and a little organic fertilizer will soften the soil in my garden enough to drop a man sized metal rod into the clay- by hand.
