I would only change the positioning of the sawdust, use it as the first layer of mulch after the working in of other organic matter.
Wood chips are just large hunks of sawdust and we use them on the surface so that any water that filters through takes some of the sawdust or wood chip goodies with it.
Sea salt will give the soil far more minerals than all the other amendments but I'd go with using the sea salt prior to planting and again after the plant roots establish for a few weeks.
Try to get some fungi growing in your mulch layers, fungi is far more important than most people think when it comes to soil.
Those are the differences I'd recommend.
Moringa is an awesome tree, it does many good things including being an edible. Leaves can be used as mulch, compost greens, tea, table greens. These trees respond well to coppice which means you can harvest lots of wood every few years (around 4 years between coppicing).
If you can, get some of your students to read through my soil series, they might like what they can learn from them.
Oh, be sure to put the cardboard down when it is wet, dry cardboard is a water repellent.
That's about all I can think of right now.

I like milk which can be mixed with rice, corn, wheat berries, or even potato. Molasses is a good source of sugars but most folks use far more than I've found necessary, the more molasses the greater the chance of growing bad bacteria (pathogens) and ciliates (bad organisms that feed on the good organisms).
Fungi have pretty simple needs and most are decomposers so woodchips or coarse sawdust work best for growing fungi, the lignin and other parts of the wood structure give routes for the hyphae to follow as the fungi break down the carbon bonds of the cellular structures.
As the fungi work, bacteria will come to feast on the newly released minerals and that gives the fungi yet another meal since fungi do eat bacteria.
