That is totally groovy. Totally. I'm just more of a granola guy is all.
Personally, I try and use local fertilizers. I collect my own microbes (BIMs - Beneficial Indigenous Microbes) to get a soil started. I make Bokashi and feed it to my worms, which make me clean, fresh castings. It's what was meant to go in the soil. I also amend the worm bin with rock powders, silica, kelp, etc. They worms lock up the nutrients best and fastest.
I like coconut water, barley sprout tea, and aloe. Why? Because unlike any of the products that can be bought in a bottle or can, these simple, almost free items contain enormous quantities of plant hormones, secondary metabolites and plant enzymes. Most of these molecules degrade quickly, so they have to be made in the field and used soon. Great for foliar and soil drench. These molecules also trigger immune responses in the plant, keeping it switched on alert, so pathogens will not only be met with a fierce microbial response, but also countered by the plants own immune response.
To me these are the subtleties that you just can't buy. I like knowing I can produce something much better than can be bought. Maybe it's an obsession
