Abstract
⺠Nitrogen fertiliser inputs to agriculture are essential for global production of sufficient food. ⺠Methane is the most efficient hydrogen feedstock and energy source for nitrogen fixation, and reserves should be protected in the absence of alternative hydrogen sources. ⺠Current known and potential reserves of phosphate rock are quantified. ⺠The requisite aggregate annual intake of phosphorus in food by the global population is estimated. ⺠It is essential that phosphorus is recycled to avoid exhaustion of reserves of this unsubstitutable nutrient.
