Barrel compost activates the soil and soil organisms, encouraging better
soil structure and quicker breakdown of inorganic and organic substances. It is
used to spread the ‘compost’ influences especially when converting farms.

Background
The development Barrel compost grew out of concern with pollution of
Strontium 90 s from atmospheric atomic bomb tests in 1958. Maria Thun and Dr
Ehrenfried Pfeiffer collaborated trialing various substances then cultivating
plants. An unambiguous result was obtained by growing plants with eggshells and
ground basalt; the plants did not incorporate or store any radioactive
Stontium90. They then set about a way to bring these two substances to the
biodynamic farm. Further experiments and trials saw the development of the barrel
compost.

Peter Proctor has developed its use especially on larger farms in
Australia and NZ where there is little compost used. In India he has developed
wide usage of the preparation. Although the barrel compost is made in a similar
fashion all around the world the quantities of compost preparations, egg shells
and basalt used vary although the amount of manure was around 50 litres End
uses also vary see table below.

Very little is written about its use in the home garden. Deb Cantrill
recommends it use for home gardeners on compost heaps, worm farms and to make
the whole garden ‘compost’ by guiding the breakdown process especially where
heavy mulch are used to protect the soil from heat and dryness. Many of the
uses in the table below are also applicable.

Home Garden Barrel Compost.
*This was developed by Deb Cantrill and the Adelaide Hills Biodynamic
Group to encourage and enable home gardeners to have their own supply thus
increasing its frequency of use on the home garden.

To make the Home Garden Barrel Compost
- Bottomless Container* Terracotta pot with
bottom cut out. - 10 litres (1 bucket) good quality firm cow
manure - 1 x 2gram biodynamic compost set
- 125gm Fine rock dust e.g. fish creek
- 50 gm ground egg shells
Method
- Dig a hole 150cm deep and place bottomless
container in hole and back fill up sides of container. - Mix cow manure, rock dust and egg shells
using a hand kneading action for 1 hour. You will observe quite a change. - Place manure mix in container, add compost
preparations as per usual. - Cover manure with a damp hession sack.
- Cover container with waterproof lid.
- After 1 month fork over manure, smooth out
and cover again. - Check every 4 weeks or so. It should be ready
in 3 months. - Remove to storage container and store as per
500.
Preparing the Barrel Compost for use
CCP is generally applied in the afternoon. For a home garden take 20gm
and place in 5 litres warm water. Stir as per 500 for 20 minutes and apply to
selected area as per 500.
