Few weeks ago we saw how to add minerals in aquaponics. I had an eggplant also called “aubergine” showing a severe mineral deficiency. The leaves were not green but yellow/grey. It was obvious, this plant was not in good health…
Deficiencies even in aquaponics pots
This plant was growing in an autopot system linked to a tank supply full of aquaponics water.
It is very common to find mineral deficiencies in aquaponics as the system is insulated from the soil and therefore the worms have no access to the deep minerals.
I am still surprised to see such deficiency in plants that are growing in a pot full of good compost hearth as it is generally high in minerals.
The autopot system is offering to the plant all the benefits of classic pots gardening plus a constant irrigation with aquaponics water rich in nitrogen.
The minerals availability is very complex. Sometimes if you add to much of one mineral it can stop the assimilation of others. The idea is therefore to re-balance the aquaponics minerals and making sure they are available for the plants.
In this event I added some rockdust powder and chelated iron DTPA and hoped for the best.
The result of minerals on aquaponics plants…
3 weeks later it’s time to check the results of this addition… The result is clear, the plant leaves are nice green and healthy! It’s a real success!
If you want to know more about the addition of minerals in aquaponics I highly recommend you to watch the other videos on the topic in this channel 🙂
