Five cousins polyculture

Has anyone heard of this polyculture including sorghum, cowpeas, daikon radishes, buckwheat and amaranth? I can’t remember the gentleman’s name who I heard this from on YouTube, but this polyculture is said to increase soil health and fertility.

I was wondering if anyone had any further knowledge on 1) why this may be or 2) why this will or won’t work.

Thanks in advance. Happy growing.

You can almost think of this as a pasture mix.

Carbon Biomass/Grass Family: sorghum,  it feeding the soil life and pumping carbon into the soil

Nitrogen Fixing Legume Family: cowpeas,

Mineral Miner/Soil Aerator: daikon radishes, with 3ft tubers that decomposes you get alot of "digging happening, plus the feeder/mining roots go down 6ft.

buckwheat and amaranth, not too sure what these guys but amaranth is in the spinach family and they very mineral dense

It was probably Matt Powers. He posted this YouTube episode here on Permies.
