This has been suggested in the past. I spoke to a fellow in a soil lab and he stated than granular wont work in liberating my phosphorus. Now I realize you cant believe everyone. Anybody have an info on this? Thanks Dave Garrell

Phosphorus solubilizing bacteria will get you the most bang for the buck David.

Your soil test always come back high in P (200 #/A +). Since keeping the pH neutrel hasn't liberated enough soluble P, we need to get it out another way. Humic acid is one way to burn some of that P out of the soil but by itself, HA can take years to work regardless of the form applied.

Here's a granular material I sell & use:

PHC Healthy Start 3-4-3 - 25 lb. bag

Healthy Start is a natural biofertilizer and soil conditioner for new planting, gardens, and phosphorus-solubilizing bacteria, and a full range of NPK and micronutrients derived from organic plant and animal proteins like bone meal, blood meal, kelp meal and rice bran. Natural humic acids are added to increase soil organic matter and serve as a rich carbon food source for benificial soil bacteria and fungi. Each 25 lb. bag treats 250 sq. ft. of garden or flower beds.

Here's a published study where Phosphorus solubilizing bacteria was used with foliar P for a possible synergistic effect that corrected the tissue deficiencies you are seeing.

Bacillus polymyxa & Bacillus megaterium are the specific bacterium I speak of. Google them for a while.

How high is the P in you soil? What problems is it causing you?

Steve I reviewed the product it looks like a good way to go as well as water soluble phosphorus with a follow up tissue test. When is the best time to apply in terms of ambient( and soil) temperature to ensure bacterial growth ? Thanks Dave

I should think that the soil warms quick on your berm. Even if it doesn't the bacteria will awake when it does warm. I'd get it out for the final till - maybe a week or two before planting out.
