Tridge summary

Chinese researchers have developed a technique to convert salt marshes into productive farmland, using crop stems to create mats that reduce soil evaporation and prevent soybean from surfacing. The method led to a 36% reduction in soil salt content and a 30.5% increase in crop yields. This could potentially address the global soil salinity issue affecting over 833 million hectares of land, and help China, the third most affected country, restore about a third of its saline and alkaline lands for agricultural use.

Scientists from the Chinese Academy of Agricultural Sciences have developed a technique that makes it possible to transform salt marshes that are unsuitable for agricultural activities into fertile farmland. The South China Morning Post writes about this. For this, the specialists were helped by the crops themselves. The authors of the know-how collected their stems and made mats from them from five to 15 centimeters long, which were immersed in the soil to a depth of 30 to 40 centimeters. This made it possible to prevent the soybean contained in the bowels of the earth from rising to the surface. Also, to reduce evaporation, the surface was covered with a special film. Thanks to these methods, the salt content in the soil decreased by an average of 36 percent, and crop yields increased by 30.5. Popular crops in the country were used as auxiliary material, as well as the plants themselves studied for productivity. The experiment was conducted in the salt flats of Wuyuan County in ...
