Our compost heaps are designed to:

  • Turn carbonaceous material into highly mineralised biologically active humus, capable of growing nutrient dense food.
  • Be aerobic: essential for it to work as soil food.
  • Make the maximum amount of high quality humus.
  • Hold the range of minerals that plants need attached to carbon, in the form of humus, making a super efficient use of the minerals that are not water soluble, so they remain in the top soil where the plant roots need them for longer. When the minerals are attached (electrically bonded) to carbon they can only be used by plants or microbes and are not water soluble and do not wash away in the rain or when watering the garden like most others.
  • Make efficient use of the compost materials we have, especially the carbon.
  • Include all 84 minerals our plants need in roughly the right relationships for optimal cell growth.
  • Use mineral sources from our own back yards wherever possible in the medium term. It’s a process.
  • Make efficient use of our time.
  • Be easy enough for everybody to do with no expensive tools or machinery.
