For the question on the phosphorus content of fertilizers when using mycorrhiza it should be a "P" of 5 or lower. You see folks using 10-10-10, 15-15-15 and so on which the "P" (Phosphorus) is way to high. If there is Phosphorus in the soil the mycorrhiza will make it available to the plant which is one of it's attributes. If you check out fertilizers that have myco's added they always have a low "P" content. Ami
