Researchers treat saline-alkaline wasteland with crop stalks and plastic covering to retain moisture and prevent salt from rising to the surface, increasing crop yields by 30.5 per cent.
Chinese scientists have discovered a crop gene that, once deactivated, can allow plants to thrive in saline and alkaline soils, a feat that has the potential to create new saline-alkaline tolerant crops, according to studies published in the journal Science and National Science Review on Friday.
