Jellyfish as cacti specific fertilizer ?
    #8943555 - 09/17/08 10:24 AM (15 years, 6 months ago)

I live in Asia and don't understand the local language very well, I was watching some news on TV, to see what was happening with a recent typhoon, and they had a segment on a new cacti fertilizer made from jellyfish or jellyfish extract, I can understand bits and pieces of what was said, but the story was quite technical and got lost along the way.
Have any of you heard about this ?

Abstract;We will describe the potential usefulness of jellyfish (Aurelia aurita and Chrysaora melanaster), which have increased rapidly in coastal waters, as a fertilizer for vegetable fields. The jellyfish were found, by means of absorptiometry, flame photometry or ICP emission spectroscopy, to have five principal components of fertilizers: nitrogen, phosphorus, potassium, magnesium, and calcium. Concentrations of total nitrogen, total phosphorus, and potassium in Chrysaora melanaster (954, 153, and 667 mg/kg in fresh weight) were 2.8, 3.3, and 1.3 times higher than those in Aurelia aurita (336, 46, and 501 mg/kg), respectively. Concentrations of sodium, potassium, magnesium, and calcium were almost identical to those in seawater. Concentrations of chromium and cadmium in jellyfish were lower than the limit of quantification for ICP emission spectroscopy. Three kinds of vegetables, chingentsuai (a Chinese vegetable), green soybeans, and perilla were cultivated using a suspension of jellyfish as a fertilizer. Jellyfish are inferred to be effective for growth of vegetables, especially chingentsuai. (author abst.)

I have heard this also, i heard in Japan they are having some major issues with MASSIVE jellyfish that were messing up their fisheries. They were scoopin them up and rotting them down for ferts. They have a fairly simple structure so composting them and attaining their nutrients should be fairly simple and quick.

Not sure on their suitability for cacti though. But i would imagine all the salts and stuff would not be great for cacti..
