Hello,  I am expanding my efforts in biodynamics enough this year to warrant looking into building a way to stir the preps mechanically.

Initial thoughts:

Wooden frame to hold a machine that points into a bucket, like the large & expensive BD stirrers in Europe

Looking at concrete  / paint  / “Mud” mixers with reverse funtionality

Something from a battery-powered tool would be convenient (but an hour stir time might not be practical)

...but I'm sure there's more ingenuity here to draw from - thanks for any info!

Thanks all!  Am looking into biochar production (I did just clear out a ton of an invasive buckthorn I could split betwen biochar and hugelkultur).

It looks like the Mg changes will otherwise be more local and gradual for this.  
(And for sure there will be soil-building activities on-top as a rule once things are in the ground, and the fungal network wil help regulate availability, I've got a lot of organic matter to work with already.)

I've had some trouble finding a good answer for this one...
I have about an acre I am converting for vine and fruit trees. The Mg is low in relation to the C for my sandy loam soil, and I'd like to increase the Mg.

The base saturation of Mg is 1.6%.   VS    33.4% Ca.

The ph is OK, it had been limed with calcitic, so liming with dolomitic doesn't seem like a good option.

Epsom salts are too intensive or expensive for such a size?

Thanks for your input!
