Better grassland fertilisation can improve the world's food supply

Global improvements in grassland management could see grasslands taking on a significantly more important role in food production. Better management would increase the production of meat and milk and prevent the need for additional feed for grazing livestock – feed in the form of grain crops that could otherwise be available for human consumption. Better management mainly involves proper fertilisation in order to retain sufficient amounts of, for instance, phosphorus in the soil. The phosp
