hey spicey, have you ever posted about your soil recycling practices? I have started to add some fresh castings to my used soil, let it sit with some moisture, and I currently use that soil in 1gal pots for fresh clones and seedlings. I would like to start going further with my soil recycling but but im not sure what to use as a starting point for reammending.
What's up grownbykane?
I haven't really posted up my recycling method in one spot, but it's pretty simple, really.
Here's the mix I started with:
Base Mix:
- Equal parts Alaska Peat, Perlite (wide range of particle sizes), and worm castings. I also added some Alaskan Humus at about 5% or so for a little extra diversity.
Nitrogen Sources:
- Crab Meal -- 0.5 TBSP/gal
- Alfalfa Meal -- 0.5 TBSP/gal
- Neem Seed Meal -- 0.5 TBSP/gal
Phosphorus Source:
- Fish Bone Meal --2 TBSP/gal
Potassium, micronutrients, etc:
- Kelp Meal -- 1.5 TBSP/gal
Rock Dusts, Minerals, etc:
- Powdered Dolomite Lime -- 2 TBSP/gal
- Azomite -- 2 TBSP/gal
- Soft Rock Phosphate -- 1 TBSP/gal
Each time I recycle, I basically add the N, P, and K sources listed above back to the soil at about 1/2 or less of their quantities. I kindof do it by feel, but I think as long as you stay below 1/2 the original amounts you shouldn't overdo anything. I also add some extra homemade castings, and possibly a little extra peat if the soil is feeling at all "muddy" from all worm castings.
One thing I think is important is that I DON'T add back any dolomite lime. The original addition should last me long time, and the soil is very well buffered and full of cal/mag from all the worm castings. Rock dusts get added back in small amounts, too; it's hard to overdo those.
