Agrikos Foundation


Stichting Agrikos is a Dutch foundation, which distributes its knowledge about the cosmic influences on crops since 1999. The foundation provides the information through publications, lectures and courses. It gives advice about tillage times for crops and initiates new researches for growers and authorities. The foundation uses the results of the researches done by Lilly Kolisko, Maria Thun and Hans Bruinsma.

Research of Hans Bruinsma

Hans Bruinsma performed his research on crop growth in relation to the sidereal Sun and Moon positions between 1984 and 1996. These are the positions of the Sun and the Moon in relation to the Zodiak Constellations. He discovered that apart from the position of the sidereal Moon, an influence that earlier has been discovered by Maria Thun, also the position of the sidereal Sun can affect the crop growth. He also discovered that the positions of the sidereal Sun and Moon can effect crops on three to four levels (Maria Thun discovered this Moon influence on only one level). By means of his results, he could reduce the occurrence of Phytophthora in potatoes by 90%. In more than 80% of the cases he found equally important differences in the manner of growth and crop health of nine other crops he examined.

The method

The method of Hans Bruinsma is based on four different principles of growth: elongation, swelling, refinement and fission. These growth principles can be effectively reinforced by the influence of the fourfold sidereal cycle of the Sun, as well as the fourfold cycle of the Moon. The sixteen tillage time effects that are thus present become available for the crops through the tillage moment. To obtain the correct balance in the plant, these tillages must be performed alternately on three to four levels. These are a sixteen fold level for the crop group, a sixteen fold product level, a sixteen fold variety level and possibly a sixteen fold breed level. Furthermore, the after-effects of the tillage times of preceding years must be taken into account. This combination of measures will ensure the required quality, health and produce.

Current projects and translations

Currently, there are two projects in the Netherlands in which cultivators and authorities participate. The results of these projects endorse up till now the results of previous researches. A summary of a part of these projects and of previous research are available in several languages. You can download these here. Recently, Stichting Agrikos also started with the publication of a digital monthly calendar for working with the sidereal Sun and Moon cycles. Translations are available upon request. For questions, suggestions or more information you can send an e-mail to info@agrikos.nl.
