"Since 2013, we have been conducting an outdoor planting experiment at two sites (with areas of approximately 550 m2 and 420m2, respectively) in the Nan’an District of Chongqing, China.
Desert landform conditions were simulated in the experiment by establishing a 15-cm- to 25-cm-thick plain sand layer underlain by a 20-cm- to 30-cm-thick gravel layer on the ground. Afterward, three types of “soilized” sand layers with thicknesses of 10–20 cm, which were obtained by mixing sand with a modified sodium carboxymethyl cellulose (CMC) solution (containing 2% modified CMC and 5% compound fertilizer) at a weight ratio of 1:0.15, were placed on top of the plain sand layer in separate sections. Three types of commercially available sand for building and construction (clean river sand), with different fineness moduli of 1.22, 2.97, and 3.71 and without any soil content, were subjected to “soilization” for the experiment. In addition to these river sands, three other granular materials (machine-made sand from stone, sand mixed with machine-made sand from stone, and sand mixed with saw-dust) were also used in the planting experiment after “soilization.” Many types of plants (Fig. 1(a)), such as rice (Fig.1(b)), corn (Fig. 1(c)), and sweet potatoes (Fig. 1(d)), were planted in the “soilized” sand. In each year of the experiment, the plants have survived the heavy rains and continuous high temperature over consecutive sunny days that are characteristic of the climate in Chongqing, China. During these periods of continuous high temperature, the plants have been appropriately watered at different intervals. The constraining material was added to the “soils” only once in the spring of 2013, and no further supplementation has been made to the “soils” after that, except for the addition of an appropriate amount of fertilizer each year since 2014. There have been two harvests each year, and the plants have always grown luxuriantly and fruitfully in the different 'soils.'"
This would be a wonderful thing for many countries, and for the world by helping slow climate change. and simple!
