    Olympus is Calling.

    Hi all, I'd probably go on the 7% total nitrogen. so that is approx. 0.07g (or 70 mg) in 1 mL of liquid fertiliser. Milligrams per litre (mg/L) and ppm are equivalent measurements so 1 mL of fertiliser in 1 litre is equivalent to 70ppm and 1 mL in 10 litres = 7ppm. That is probably a bit...

    Hi all, I assume it was <"developed for the USA">. If I wanted to create a fertiliser that produced a pretty instant greening response, it would be something with a lot of nitrogen, and probably in the form of urea, to reduce the risk of <"fertiliser burn"> in terrestrial plants. My guess is...

    Hi all, Have a look at @Bart Hazes <"posts">. The "Miracle-Gro", (from the <"It's very Green thread">), perks the plants up pretty instantly. <"I guess it is the urea"> content, but I don't actually know. cheers Darrel

    Hi all, Yes just to keep the pH below pH7 and make sure all the TAN was as NH4+, it would stop it degassing and it would ensure that the ammonium ion was plant available. The other advantage would be that it may limit microbial nitrification, even if some microbes survived the initial...

    Hi all, Afternoon John, my apologies to Karl as well. Curiouser and curiouser. I don't know if @alto has any thoughts? Could you try it again at without remineralizing the rain-water? I might add a dash of white vinegar (or Vit C./Citric acid) as well, that should ensure the pH is below pH7...

    Hi all, What was the nitrate measurement at the end of the experiment (or the combined NO2 + NO3 levels)? I can't see a mechanism for nitrification, but that doesn't mean that I'm not missing something. cheers Darrel

    Hi all, No, it definitely doesn't invalidate your result, whatever happens you have contributed to the sum of human knowledge. If people try similar experiments, and come up with similar results, then we know that our present view of ammonia uptake in plant/microbe systems isn't right. But...

    Hi all, I honestly don't know what happened to the ammonia you had added. It may have undergone nitrification etc. , but there are all sorts of questions. Did you start with RO water? If you did? What other nutrients did you add to it? etc. If a study has been published as a peer reviewed...

    Hi all, Honestly you can't conclude that. There is a huge amount of scientific literature that looks at <"TAN removal from waste water">, some using <"nitrogen labelled isotopes">. One point would be that plant nitrification is always "plant/microbe" nitrification, it is almost impossible to...

    Hi all, I must admit, before today, I had no idea that urea had such a low toxicity to fish. If I'd known more about animal physiology it would have helped, but the penny should still have dropped a lot earlier. I've been regarding urea and ammonia (NH3) as toxic at much the same...

    Hi all, I'd just be paranoid about a pump malfunction dumping a large amount of urea in the tank. In the short term it wouldn't be like a CO2 dump (<"urea has very low toxicity to fish">), it would just depend how quickly the ammonia was liberated, and how much was mopped up by the plants and...

    Hi all, A lot depends on the wood. In my experience these types are the most resistant to decay. Real "bogwood", wood that has been encased in a peat bog for hundreds, or thousands of years, Oak (Quercus robur) heart wood, from either branches or roots. Douglas Fir (Pseudotsuga menziesii)...

    Hi all, That is interesting, and spectacularly chlorotic . <"What about manganese"> (Mn)? It isn't plant mobile and its deficiency causes chlorosis in hard water. Very high Fe:Mn ratios can also effect Mn++ ion uptake. Molybdenum (Mo) definitely isn't mobile within the plant either, but (in...
