Pre-planting soil ammendments. Picture is the soil I use. I always adjust it before I plant. If you mention NPK give a ballpark % of increase. Looking to see what others would do to ammendments this?

I would roughly add (per 10L soil): - Worm castings ~ 1–2 L - Manure pellets ~half a cup - Dolomite lime ~ 1-2 tbsp - Mycorrhizae Rock dust (basalt or glacial) ~ 1-2 tbsp Optional: kelp or wood ash (tiny amount) if you need more readily available K Depending on the structure clay pebbles/perlite, as wanted/needed. No guarantee. 😋
