The rate of shampoo is 3 ounces per 1,000 square feet. It's been used up to 50 ounces per 1,000 with no ill effects, so you don't have to worry too much about over doing it. Check the hardness with a screwdriver. See how far it goes into the soil easily. Use the shampoo followed by 1/2 to an inch of water. Check with the screwdriver again in 3 weeks. I use generic baby shampoo. You can use any shampoo you can see through (no conditioners).
I've tried molasses at every concentration and never found it helped anything. Then again I had been organic for years before trying it, so maybe all the benefit had been achieved. Dry molasses is made by pouring 15 pounds of molasses on 35 pounds of crushed corn cobs or other inert material. Find your local farm and ranch COOP, not feed store, and see what they sell bulk molasses for. I get it by the gallon for about a dollar if I bring my own container.
Milorganite is fine. I use ground corn meal or alfalfa pellets (rabbit chow) at a rate of 20 pounds per 1,000 square feet.
