help a noob

well aint that  a pisser i wrote a whole post and lost it as the pictures were too long. The area i live in is very dry to give you a idea of how dry this is the natural land scape for the area.

since i cant show a picture il discribe the area its a small area on the back of the house thats about 4 feet by 17 feet. it is bordered by wood and has a rock path and pavers all around it just to the other side is another mulched bed with a trellace esk thing that was orinally for a hammock that has sence found its way to the garbage heap.  I want to do the lasagna style but I dont really think i need to drop alot of cardboard as the area is basically dead a few weeds etc but all in all its almost all sand not soil and nothing wants to live in it. Im going to go light on the newspaper where the weeds are but i just want to drop in cow dung with hay on top and start the legumes going.

I am using this video as a guide as i have recived a free copy

But i have a few questions.? in the video he dips his ground cover legumes in some sort of mold growth agent that is saposed to help start the nodes that do nitrogen conversion what is the name of this stuff and doo i need  certain type for certain plants.

My plan is to start with perinal penuts pigeon peas and moringa olofiera. This is what i am confused on when is it that you should drop in your none legume vegies as im not looking to plant fruit trees . The only plant i want to put in that fruits is my passioflora edualis plant that will only root on this side as it will grow over a trellace esq thing via bridge from this bed to the other.I want to tree the moringa olofirea but all the rest i would happily chop and drop even though i would like to get some of the food yield from them. Also any suggtestion on a ground cover the has a higher food yield thant perenial penut.

answered one of my own question found a good artical on rhizobium. I also failed to make a general appeal to other south east florida permies for tips and tricks for how to make this work in our hot climate. 

An on-line nursery that sells the seeds of pigeon peas will also likely sell something to innoculate the seeds with bacteria to help them fix nitrogen.

I have no answers for your other questions, though someone else is likely to wander by who can!

Our soil is *very* dry in the summer and we had to import some innoculant before we could get any beans to grow.  We would grow them in a raised bed, to try to concentrate the bacteria, then the next year we would take that soil, add water, and soak a load more beans in the water before planting them.  We also mulched as heavily as we could when we planted them, and after about three years of doing this, beans will grow pretty well anywhere we plant them without using any innoculant. 

Thanks for the tip do you think that is because your soil to on the rhizobiom for the beans or because your beans became accustomed to the native rhizobium???
