I denne artikkelen er metoden nærmere beskrevet.
De startet altså i 2016.
The desert sand and the constraining material were first mixed using a mixer and then paved onto the desert surface with an average thickness of 10 cm (Fig. 2(a)). A nitrogen-phosphorus-potassium compound fertilizer was also added at a weight ratio of 0.3% with respect to the sand. The “soilized” sand possesses a strong water retention capability (Fig. 2(b)). A spray atomization irrigation system was used in the experiment (Fig. 2(c)). In an attempt at large-scale mechanized preparation, we even used a rotary cultivator to mix the “soilized” sand and apply it over an area of 2000 m2, and the results suggest that such a mechanized preparation approach is feasible for large-scale desert “soilization”
=mye jobb og må jo være en stor kostnadsdriver.
Dette er interessant (bilde f). Betyr ikke det at det blir et badebasseng uten like om det kommer stor regnskyll?
) the water still retained in the 20-cm-deep hole in the “soilized” sand 24 h after it was fully filled up
