It was tested in the Station facilities, and had shown the ability to survive on only basic nutrients, airborne moisture, and a minimum of supplementary watering.
Poverty grass was planted in 12 planting zones, along the downwind sides of old dunes, where it stabilized the sand against the prevailing westerly winds. Each stabilized area accumulated a higher windward crest after each sandstorm, which would in turn be planted with poverty grass, until sifs (barrier dunes of more than 1,500 meters' height) were produced. In all but 4 of the test zones — in which the grass refused to take root — three barrier dunes were ready in a matter of months.
