Dolomite takes around 24 months to breakdown, depending on the total volume of soil, you may still have sufficient values. Your unlikely to venture into an elaborate testing kit for various elements, but a simple slurry sample tested with litmus paper can show the pH. Since I'm assuming your peat based, your pH will be low if your lime values are lacking.
Thanks for the reply! My base is organic soil mix, coco coir,worm castings and course perlite! I added dolomite,epsom salts and i decided to add a little bit of gypsum. Using 7 gal pots. In aus only have access to basic soils and compost. Just went with organic soil base with no fertilizer added!
Your soil doesn't contain any peat? In that event I'd ammend with oyster flour/meal or granular gypsum, dolomite can cause issues with pH in coco dominant organic fed soils. Sounds like your on the right track. If you can get your hands on leaf mold (composted leaf litter) that can add more chelation via humates, and help to release any calcium that has bonded with phosphorus inputs. Continued Recycling helps with this as well.
Thanks again for the reply GG421! Can't get any leaf mold would leonardite (humic acid) do the same job?
Fulvic would be better. But yes, any organic acid will help with chelation.
Leonardite contain both. It's kinda impossible to have humic acid without fulvic acid and their definition is not clear or even set in science.
I've been under the impression that fulvic has a smaller molecule. But yeah aside from that, they're both of the same. Can't go wrong eitherway.
Fulvic acid is obtainable I will
Thanks for your input Wastei! I saw that leonardite has both humic and fulvic when I compared it to the leaf mold GG421 was talking about! I used a small amount of leonardite in the original super soil mix.
I found it harder to use and dose fulvic acid properly running salts. It's probably a better input in organic gardening than mineral salts where minerals are already in ionic form. Fulvic acid can easily cause burns in a salt based grow and leave some minerals more accessible than others if overused.
A full batch of subs s/s was to much for my intended use. I broke down the recipe to make 15 gal only. 2x7 gal pots some left over for maybe a top dress if needed. Leonardite was added to the original mix, I have researched through this site that to reuse this s/s I only need to reammend with 1/3 of ammendments and let cook to use again. Would this be accurate ? I'm growing auto's outdoors and it's intended to be water only! So far so good. Thanks for your input.
