Rice, like all plants, needs phosphorus to grow. But there’s a problem for this crop, the most important calorie source in Asia. Much of the soil it’s grown on is low in phosphorus, and yields suffer as a result.

The trick was to go back to rice varieties from east India that are known to grow better than most in poor soils.
