Order straight from the Upper Austrian thermocompost factory. By doing so, you not only care for your immediate environment by transforming kitchen waste into something valuable.. You also support the Austrian economy, saving valuable jobs for locals.
We all like to do our bit. Composting helps to reduce the waste and contributes to a less mixed rubbish in communal disposal sites. It also takes the user closer to nature and brings home the life cylce of organic foods, helping us to convert our food waste into soil by speeding up the decomposition of organic material. This rich soil helps us gardeners to produce delicious fruits, vegetables and flowers. And consequently we will know where the stuff comes from that lands on our kitchen worksurface and dinner tables.
Although the whole process is actually quite complex, there are a few simple facts, that can help the discerning gardener to use the composter very effectively.
Important is the combination of carbon-rich (browns) and nitrogen-rich materials (greens) correctly as we want them to break down to humus, using the right quantity combination, together with air, water and microorganisms and some time, usually a few months. An effective compost consists of about 25 to 30 parts of Carbon and 1 part of Nitrogen, making sure it is mixed well.
As you have figured by now, to dump a huge pile of fresh grass cuttings is not very condusive to creating good humus quickly, as grass (greens) have a low C:N ratio.
The main disadvantage of too much carbon is a a very slow decomposition.
The disadvantage of too much nitrogen on the other hand is a smelly compost, as it releases ammonia.
These are some examples of carbon richt materials, including the approximate ratio:
leaves (60:1), pine needles (80:1), Newspaper (175:1), Cardboard (without tape, print, staples etc.) 350:1), wood chips (400:1)
Nitrogen rich materials on the other hand are:
garden waste (30:1), hay (25:1, food waste (20:1), coffee grounds (20:1), grass clippings (20:1)
In addition to just the materials, the all important microorganisms need oxygen and water to help them consume and digest the organic materials in a compost pile. The decomposition is an aerobically and anaerobically process, althoughg anaerobic decompostion is slower and produces a bad smell. Moisture promotes microbial growth. Although too much water inhibts the transfer of oxygen to the microbes and contributes consequently to anaerobic behaviour. And this has nothing to do with a dislike of aerobic exercies.
