I got an idea to increase farm land production based on the idea of putting your plants on top of rolling platforms by @andstephen , a new member here!
Imagine platforms the size of a flatbed truck, but simply a platform with a soil bed about 30 cm deep on high legs with wheels (high enough to stand under) so that you can use it as shadow/shelter and make the legs hollow so they can serve as water tanks for watering and for cattle and any other farm or wild animals that would eat the plants, but they can’t because the plants are growing one story above them.
This way you can get some extra use out of a grazing field.
And one can pull the rolling cultivation platforms to a different position anywhere, any time, and perhaps shelter them from storms if you have a high enough hangar or barn or greenhouse.
Could also make smaller thinner ones and scatter them in a garden that has 1 m wide walking paths made of woodchips inoculated with mycorrhizal mushroom spores/mycelium for example.
Using the same footprint to cultivate mushrooms as well as plants.
You can roll the platforms on there without them being in the way while you harvest or prune as you can stand under them or push them away from where you need to be.
The wheels can be like those of a quad bike perhaps, and could be designed to be pulled by a quad, many in a row.
Double or triple deckers are a possibility too, my setup including LED is only about 1 meter high.
So extra lighting can be used both outdoor and indoor with waterproof LEDs.
One can use a long cable or batteries.
