Tierr@_de_N@die: Phosphorus is used all around the world to improve harvests. It has worked very well during decades but farmers face two different type of concerns using fertilizers: the scarcity of the resources and the negatives environment effects of the abusive use of these components.
Researchers now want to create smarter crops. In 2012, scientists identified a gene in an ancient variety of Japanese rice that enhanced the plant’s ability to find phosphorus by growing fine roots. Researchers then bred the trait into modern rice plants, and in 2019 farmers in Madagascar—which has naturally nutrient-poor soils—started testing some of the most promising varieties.
