Unified table of herbs: soil-forming → forage → edible

In this article, the grass layer is considered as a system: first roots and sand fixation, then nitrogen and biomass, then feed and only after that limited edible crops.

First the roots, then the harvest

For a coastal desert, it's important not just to select "useful grasses," but to arrange them correctly according to their functions. Initially, the grass should act as an engineering layer: fixing the sand, reducing evaporation, providing organic matter, and promoting microbial life.

Edible and forage species appear not in place of soil-forming plants, but rather on top of an already prepared base. Therefore, the main principle of this table is: soil → nitrogen → cover → food.

Three functional layers

Soil-forming layer: dense cover and fixation of sand

Forage layer: biomass and stable cereals after site stabilization

Edible layer: greens and cover crops only in the protected area

Unified table of species

The table lists soil-forming, nitrogen-fixing, forage, and edible grasses. Water, salt, and root type determine where each species can be used: in open sand, in a protected area, near water, or only in a demonstration plot.

How to use the table

1. Soil Cynodon, Aeluropus and Vetiver fix the sand and create a root framework.	2. Nitrogen Medicago and Trifolium add biomass, humus and microbiological support.	3. Cover Portulaca and Carpobrotus cover the surface, retain moisture and reduce overheating.	4. Food Amaranthus and green herbs are introduced only in a protected area with water control.

Minimum starter kit

To get started, a simple mix is all you need: Cynodon + Aeluropus + Medicago + Portulaca + Vetiver. This mix is capable of fixing the sand, starting to form the soil, providing organic matter, and preparing the area for the next layer of planting.

Conclusion

Grasses can contribute up to half of a project's success because they are the first to transform inert sand into a working surface. Trees only become stable once they have roots, a canopy, organic matter, and retained moisture underneath.
