Hi phivtoosyx,
I googled Palm ash and found the following points of interest.
Quote: Palm ash:
Major component is palm waste, soyabean dregs. Non-vermicompost. Palm waste-based organic fertilizer. Fermented with EM.
1. Nitrogen as N 4.8%
2. Phosphorus as P2 O5 1.6%
3. Potassium as k2O 4.8%
4. Magnesium as MgO 0.7%
5. Copper as Cu 21 Mg/Kg
6. Zinc as Zn 41 Mg/Kg
7. Ferum as Fe 0.2%
8. Manganese as Mn 271 Mg/Kg
9. CaO 1.5%
10. B 1 Mg/Kg
In aquaponics it's advisable to avoid the addition of copper to the system, for the sake of the fish.
Quote: Palm Bunch Ash is a fertilizer from oil palm fruit ash (the empty fruit hulls are burned and the ash is collected and used as a fertilizer) which is a source of Potassium.
From my own personal POV, I wouldn't use any products knowingly derived from the production of Oil palms.
Oil palm production is causing widespread environmental degradation in SE Asia... and only a few days ago it was reported that 30+ Orangutans were killed by workers from one plantation alone.
Not preaching, but here is a link to an article that covers both the animal cruelty and negative environmental aspects of Oil palm production: http://www.cosmosmagazine.com/news/1496/palm-oil-workers-killing-orangutans
Quote: Are there any problems associated with adding banana skins to a GB for potassium?
Hi DuiNui,
I'm not sure if your question was a general one for the forum, or whether it was aimed at phivtoosyx asking if he had an issue with adding banana skins to his system as an alternative to the Palm ash.
If it was a general question for the forum, I can tell you that I haven't had any isuues with adding Banana skins to my systems. I bury the skins in my gravel at the high water level. You will need to add some composting worms to your GB before adding any banana skins, otherwise they may just rot and turn to goop in your GB.
Cheers.
