Hi everyone,

Did a big shed clean out a few weeks ago and came across a bag of zeolite.
Now I don’t remember what its for. Can anyone enlighten me?

zeolite is a useful mineral you can add to your soil that attracts and hold nutrients in your soil so they don’t get washed away but makes them available to the plants.

oh……. I remember another product now river safe? something like that.
This was just in a bag no information at all, so glad I didn’t throw it.
So it must be ok to use in the veg patch, thanks bg

definitely good to use in the vege patch :)

I add it to my sandy ‘soil’, along with bentonite and spongelite.. although I haven’t bought the spongelite yet, that’s still on the list.

It specifically holds onto Potassium well. Preventing leaching.

a fair amount of detail on zeolite is on wikipedia page http://en.wikipedia.org/wiki/Zeolite
i used a bag of cheap cat litter (marked as pure zeolite) in a section of garden bed. the granules seemed to have broken up in the soil, so i didn’t get a long term effect i was after that time—more larger particle size in the soil. apparently there are different grades/types of product available from the various zeolites. i do remember the zeolite used in aquarium filters, which was more porous and resisted dispersion/breakup in water.

the garlic in the zeolite treated section did grow well…but i couldn’t tell much difference to the other garlic growing sections. i’m sure it did some good to the soil anyway. if i ever do use it again, i might use it as a thin dressing over freshly seed sown soil. it should further prevent caking of soil that must remain bare until plants are big enough to mulch around. And it should prevent the all important top 1cm of bare soil from drying out in wind….although that’s much less of a problem in my soil these days. it would be much more economical used in this way. when i dug a 20kg bag of it into the soil (1×1m patch) it was not a cheap/economical soil amendment. anyway, that’s my experience using zeolite for the garden to date. i’m even considering strewing some of it in the duck enclosure, to reduce flies.
