Inorganic soils:
decomposed granite (hard, less water absorption)
seramis (grains of crushed red brick)
haydite (Extended shale)
sand ...

Inorganic Soil Mixes and Components
The advantage of inorganic materials is that they hold their open structure for a long time without breaking down into mush.

I. Inorganic - No Carbon
Minerals - Esp. Fungicides (Copper Sulfate, Boric Acid)
Salts - Esp. Herbicides, some fertilizers (MgCI)
II. Organic - Contains Carbon ...

Inorganic Soil
In the past decade, there has been a significant move towards inorganic soils. Though organic soils are cheaper and more easily available, they are also of inferior quality.

Inorganic fertilisers come in liquid and or solid forms and have a strength depicted by its NPK value. For example a fertiliser which has an NPK value of 10:10:10 means that it has all the primary nutrients in equally quantities in the preparation.

Inorganic structural element: lava rock, perlite, sand, baked clay, decomposed granite, pumice, etc
Organic structural element which can hold some water and nutrients: fir bark, pine bark, nitrolized redwood chips, etc.

Inorganic - sifted gravel [ silica ] and crushed red brick
Organic - sifted compost or manure.
Usually 1/3, 1/3, 1/3.
Douglas r Wood MD from northeast Auburn, Maine, US, says : ...

Inorganic elements and compounds, such as clay, granite, ash and others help regulate drainage and supply nutrients.
Ash or ground volcanic rock, helps not only regulate water but supplies some of the needed nitrogen as well.

- Inorganic fertilizer is chemically constructed but performs the same task. The main difference is the rate of release (nutrients), which is slower and more efficient in organic fertilizer ...

Organic and Inorganic Components for your Bonsai Soil Mix
When creating your soil mix, you have a choice between using organic and inorganic components.

Bonsai ‘soil' is a mixture of organic and inorganic compounds that provide a
suitable growing media for the cultivation of bonsai trees within the confines
of a bonsai container. A bonsai container or pot is an unnatural and ...

All soil is basically made up of two components organic and inorganic. Organic comes from living things such as bark, sawdust, leaf mould, animal manure or compost.

Vermiculite is commonly used in bonsai soil as an ingredient to achieve the inorganic content ratio. It is a mineral in the silicate family. What makes it perfect for any kind of bonsai is the fact that it is neutral and water-absorbent.

Do not over fertilize with strong inorganic chemicals, and never, ever, fertilize a dry pine.

Akadama, a white Japanese clay, is the most commonly used fine-quality inorganic material used by expert bonsai artists throughout Japan. But it can be hard to obtain in the US and UK. Seramis is often used as an alternative.

Organic (less concentrated, slower acting, complex with other substances, e.g., fish emulsion, bone meal, blood meal) / Inorganic (concentrated, quicker acting, simpler/purer chemicals, e.g. MirAcid® or Grow Power®) ...

Some promote the use of organic fertilizers to augment an essentially inorganic soil mix, while others will use chemical fertilizers freely. Bonsai soils are constructed to optimize drainage [4].

One of the major advantages to inorganic bonsai soil mix is that they are able to hold their open structure for a long time without breaking down, ...

These affect bonsai trees just like other plants but can be treated using traditional organic or inorganic treatments. Remember that prevention is better than cure! The risk of diseases can be minimised by adopting good horticultural practice.

It is an important aspect, but here the opinions differ very much: Some promote the use of organic fertilizers to augment an essentially inorganic soil mix, while others will use chemical fertilizers freely.

Inorganic fertilisers (chemicals) come in different forms: dry, liquid, slow-release, pellets, plant stakes, soluble solutions, and many others.
Do not overfeed your Bonsai and forget fancy diets. Your Bonsai does not eat, it drinks! ...
