Intensive high-yield agriculture is dependent on addition of fertilizers, especially industrially produced NH4 and NO3. In some regions of the world, crop production is still constrained by too little application of fertilizers. Without the use of synthetic fertilizers, world food production could not have increased at the rate it did and more natural ecosystems would have been converted to agriculture. Between 1960 and 1995, global use of nitrogen fertilizer increased seven-fold, and phosphorus use increased 3.5-fold ; both are expected to increase another three-fold by 2050 unless there is a substantial increase in fertilizer efficiency. Fertilizer use and legume crops have almost doubled total annual nitrogen inputs to global terrestrial ecosystems. Similarly, phosphorus fertilizers have contributed to a doubling of annual terrestrial phosphorus mobilization globally. See more
