Desert microbes could halt desertification in Middle East

MENA looks forward to agricultural boost

Desert soil microbes could help halt desertification and boost agriculture in arid regions of the Middle East and North Africa, according to a study.

Scientists from the United Arab Emirates [UAE] have isolated local salt and drought-tolerant strains of Rhizobia, soil bacteria that fix nitrogen when they become established inside the root nodules of legumes.

Rhizobia bacteria establish a mutually beneficial relationship with their host plant in which they exchange nitrogen they fix for nutrients plants produce through photosynthesis, and could be integral to improving the quality and nitrogen content of soil.
