Fulvic acid

Has anyone had experience of fertilisers containing fulvic and humic acids?

 

Only heard of humic acid in regards to altering the ph of pond water, but I think it is pretty much the extract from humus.

 

Given that they are products of plant decomposition I would expect them to be present in compost, leaf mould, sea weed fertilisers etc. They are mixtures of complex organic acids, they can hold magnesium, calcium, iron, sodium and potassium ions in the soil, making them available to plants, they also probably help soil structure.
Any advantage in adding them separately rather than as part of garden compost or leaf mould, no idea.
As an aside; apparently they are also used as food supplements for people and are apparently good for any complaint you care to think of.

 

I bought an extract for orchids containing fulvic acid. Not sure if orchids liked it. Will use somewhere...

 

growth tech use humic and fulvic acid in loads of their organic fertilizers, I use quite a lot of their products, i like green future organic tomato feed and use quite a lot

 

Thanks for your responses! They read like most of what I've read myself online. I was hoping to find someone who'd used some of the newer fertiliser mixes ("like the professionals use!") I've used one from Medwyn Williams' site and must admit it seemed to work well if a little better than the straightforward NPK ones. However there's nothing like a prolonged trial!!
I'm interested from the point of view of trying to aid using the variety of So-called PEAT FREE composts.
I'd agree that OWN composts containing really well made garden compost, and leafmould in particular, are bound to contain humic/fulvic material. However these 'magic' formulae MIGHT be the bees knee!

 

Fulvic and humic acids have slightly different characteristics. There are a heap of products around that contain these. I'm trying to avoid getting kicked off here so I'm not posting a link to a blog I write but if you go to the website listed in my profile there is a heap on biostimulants which is what these fall under.
