    Has anyone had any experience with using coffee grounds? We have a coffee factory near us so we’re thinking of spreading the spent grounds through a waste contractor.

    Having searched the internet there are a few research papers looking at potential benefits and effects.

    Has anyone had any experience with them?

    they might work over time.
    Some of the research suggested it can inhibit plant and microbial activity, and others suggested it promoted plant and microbial activity.
    Going to do a few tray tests to see.

    Coffee grounds certainly make good compost. David Montgomery and Anne Bikle wrote in their book The Hidden Half of Nature about how they used a lot in Seattle and transformed their garden from no soil to deep and fertile soil in next to no time. Presumably spreading the grounds would feed the soil creatures and start the process. As you say, they should work double time

    My experience in a garden situation it works. However some strange EU legislation makes it illegal to use coffee grounds for slug control.
    Make sure your application reasons are for anything but slugs.
    Also it could be classed as industrial waste so claim the caffene is a foliar feed. Should move it into a grey area where their rules are lost.

    I've seen it used, nothing spectacular at a field scale but typically a reasonable source of OM and some nutrients.

    Full EA deployment and associated restrictions - all at the contractors expense of course. Should be delivered and spread FOC on this basis, maybe even paid to receive if you had year round artic tipping etc.

    2 cups a day we'll have a good heap in 20years?

    I believe @Jason and @Fred are referring to the material that comes out of the Kraft factory in Banbury. I have experience of this material and as mentioned its a useful source of OM and a bit of nutrient. It can be composted but why bother. It has a reasonably low C:N ratio so in low applications (20t/ha) it shouldn't cause too much concern (unless in a carbon building zero-till system). It has a bad rep in the past due to people applying it at rates that needed a bulldozer to spread!

    Having been dumping tea and coffee grounds in my wife’s herb trough all year, I can say it grows the stuff well. No slugs either
