Extremely old compost
 

We recently had to use the space where the compost heap was. The heap
was started at least four years ago and could have been much older than
that even, we had just added and added to it over the last three years
without using any of it. Anyhow we put most of the really old stuff
which was at the bottom of the heap on the garden.

The compost seemed like excellent stuff but I was wondering whether it
can actually be too old to do any good, or, older the better type of
thing. Does anyone have any thoughts on this please?

If it's free of weed seeds and roots, old is fine as a soil conditioner.

Soils lose organic material-a light soil might lose most of its humus in 2
years.( I have the reference)
The compost is precious. In my own garden-(heavy soil) I would put it on
raspberries (aerated fibrous roots), strawberries, redcurrants. Also on
plants that like a well drained but moist location etc.
If there is any left over I would dig it in.

if it was exposed to rain some of the nutrients may have leached out of the
compost into the soil underneath (can't tell you how much per year, how much
in total, way beyond my knowledge base). That is why you hear people talking
about digging 20 cm (or whatever depth they choose it seems) down into the
soil the compost has been sitting on. This way you dig into compost leachate
enriched soil. Really old compost will be very much like soil anyway so will
be perfectly fine for the garden even if it has lost some nutrient. Digging
up the underlying soil will help capture some of the nutrient loss.

No matter how old it is, you'll still be getting all the benefits of
the organic matter - humus - which is a vital addition to the mineral,
sand etc, and clay particles which are the other main constituent of the
soil. Providing it's never dried out completely there should also still
be plenty of bacteria and other beneficial micro-organisms. Although maybe
not as many as when there was more fresh material for them to work on.
These are another essential element provided by compost. The fact that
you may have lost some nutrients through leaching is neither here nor
there IMO. As unlike organic matter and micro-organisms, this deficiency
can always be remedied by the use of the appropriate fertilisers
in any case.

If you find any brandlings in the compost as you fork through it, the
worms with dark red rings, you could save those and introduce them into
your new compost pile. They'll survive in soil, although not as well
as earthworms, but will do much better in a compost heap. Ideally with
something soft to get them going. Week-old banana skins etc.

Thanks for your thoughts on my old compost folks. I have already
forked it into the veg patch and the borders Janet so unfortunately the
night-soil operative won't get his/her hands on it or my demented
worms! I wondered why they were acting strange :)) Now I know.

The worms we found in it and there were absolutely loads, we also
tossed into the veg patch with the compost. I think these were earth
worms. The red ringed type are always around the underside of the lid
of my plastic composter and the ones in the old compost heap were
normal looking. I have to admit this will mean I have been committing
some worm cruelty Micheal because I have been throwing the brandlings
onto the veg patch at every given opportunity, so I have probably
inadvertently killed quite a few of them then? In future I will chuck
them into the composter instead.

I have been thinking a lot lately about having a wormery, at least I
think that's what it's called? Apparently I can put all my green
household waste in it and I believe the juice they create from the
waste is fantastic food for the garden? Anyone else got one?

I'm off to Google it.

Do not part with any money. As you have already noticed your compost bin was
eventually invaded by loadsa worms.
Rats are attracted to kitchen waste so a sealed wormery is useful.
Any container with a few drainage holes will do along with an initial few
small red worms. Forget all the rubbish about worm bedding and acidity
regulators-just ensure that the system has adequate drainage.
I pour the liquid tea on the compost heap.
The process is slow so do not expect vast amounts of liquid or worm crap
unless you are prepared to build massive wormeries.

it's called vermiculture.........

crawlers which in appearance look like worms on steroids...............
