Biodiversity is the variety of life and central to sustainable development. It is critical for reducing poverty, creating sustainable livelihoods and helping communities to adapt to climate change.

We want to enhance biodiversity to improve evolutionary refinement so that people can grow their own safe and secure food, by sharing knowledge and market suitable equipment.

Preservation, refining and development of local grain species.

The preservation and processing of original old and local grain species, is a challenge in today’s industrialized farming.

In the old times, the farmer saved some of the harvest as seed for next year. This was managed in the best way possible. The farmer had control over the whole process from the seed to harvest and saving seed for next season, himself.

Today, in the industrialized agriculture, the farmer has become a manufacturer that sow the seed and his task is to get the greatest possible crop. Management of seed is not his focus – that is taken care of by specialized companies. The whole process is ruled by money.

To preserve old local species and further development in accordance with the nature’s laws, need innovation. In livestock production sheep, cattle and pigs, the best breeding animals are selected from great populations based on breeding capacity and other quality measures. In grain cultivation, the cultivation is no longer a tool for selection of the best combinations.

First, it must be acknowledged that nature has a genetic diversity that allows it to evolve in many directions. Old Darwin taught us that “the strongest survive” – Evolution. All processing of plants and animals has built on this principle and we have brought forth species which, in some cases, is virtually unnatural.

Secondly, one must realize that the pursuit for effective cultivation methods giving the greatest possible economic dividend, have resulted in a reduction in biodiversity and the genetic diversity.

In a crop there will be a great variation in the genetic combinations as germination, resistance to diseases, yield, allelopathy characters, etc. The target is to separate from the entire crop the part that has the best characteristics in this respect.

Our principle assumes that the grain which has the greatest density has the best characteristics. The density is determined by weight compared with volume. This is well documented with several research projects.

To separate the portion of the crop with the greatest density, we use an aerodynamic cleaning and separating machine. The principle of the machine is shown below. The machine is easy to operate and relatively inexpensive to acquire.

By utilizing the grain with the greatest density as seed for next season, we get a guided evolution. In addition to enhance and develop a population, we can use the same technique developing a new sort.

If we combine this methodology with ecological farming methods, we take care of nature’s own wealth and genetic variety to the joy and benefit of whole world!

Principles of an aerodynamic separation machine

The fan (down right) blows a constant airstream through the chamber. On to grain is falling through the airstream and is picked up in the pockets (down left). Heavy particles like stone and metal will fall in pocket 1, heavy grain in 2 and the lightest in 5. Dust etc are blown out.

You can regulate the power of the airstream, the amount of grain that is falling and the openings of the pockets.

Heavy grain may be used for seed (pocket 2 and 3), lighter for food (3 and 4) and lightest for animals (5).
