- Sowing and planting of pioneer vegetation as precursor of agriculture, horticulture and forestry (see the so-called method of v.d. Meulen.)
- Application of ecological techniques in which the soil is always covered (compare with a.o. the Rusch-Müller methods.) 
- Forestry (wood production through pioneer vegetation)

To achieve:
1. Climate regulation: adecuate humidity regulation through reduction of the wind speed.
2. Protection of the soil: prevention of the wind erosion, of the carry off of the soil and of sun burning.
3. Water regulation: sponge effect of porous soil.
4. Wood supply: of a certain economic importance, but with conservation of the degeneration cyclus.
5. other products, of which many are of great importance for the inhabitants.
6. Genetical reserve: a tremendous, awe imposing and available richness of forms of life.
7. Animal world (fauna): many animals will live in a great measure depending on this vegetation growth.
8. Unmaterial significance: source of nature enjoyment, knowledge and respect.

The photosynthesis, as an assimilation process in the plants and water vapour in the combinations of carbon and hydrogen, indispensable for the human being and for the animals as source of food and energy, speaking then of the biomass conversion of the sunlight.

We may consider the sun and the plants as great constructors, whereas the human being and the animals as consumers, operate the oposite process. The constructors and the consumers thus create a circular course process. Therefore it is impossible for us to live without the green plantrobe. The sun is the motor of life. Thus men can be provided permanently with food in a natural way, leaving the non-regenerating energy-carriers in the soil as a reserve.

An ecological method: 
this can be separated in three principal parts:
1. The ecological soil regeneration
2. the ecological soil conservation
3. The simultaneous rotation.
Practically:
The Centrosema Pubescens is capable of attracting the humidity of the surrounding athmosphere with its leaves, and to depose this in the soil. Dry air, as given in the deserts, still contains water vapour and receives it also by diffusion processes and through apport of air turbulention.
The Pueranica Javanaica is very good together with aforenamed plant. In between, one will sow Mimosa Invisa in rows mixed with the ever-green Centrosema, as it is very inflammable after drying. 
Where there is a clear lack of mineral salts, this lack wil have to be filled in with fertilizer. But always as few as possible. The Centrosema grows easily in the shadow. This allows to make an specially high amount of organic material by planting higher growing composite shrubs, as are: Eupatorium Odoratum, Tephrosia Candida and others.
 

The Babassu palmtree gives clusters of very hard and heavy nuts, which we can see as concentrated sun energy. The harvest is +- 90 Ton per Ha per year. Through the technical process of the dry-distillation we gain charcoal, methyl alcohol and wood-gas.
Besides this Babassu (Orbignya Martiana) we also know the Orbignya Atalex. Different sorts will be very suitable for the production of valuable biomass.
Agriculture and horticulture give healthy and good food, which is achieved by an as great as possible diversity in crops which contain many sporenelementen and enough albumine, grown on a biologically living soil which gives the right bacterias to our intestinal flora, by which the immunity system of the human being is being rebuilt.
(as by know-how of Van der Meulen.)
