How much fertiliser is used each year?

Answer 1

The global use of fertilizers varies annually, but estimates suggest that around 200 million metric tons of nitrogen, phosphorus, and potassium fertilizers are applied each year in agriculture. This amount can fluctuate based on factors such as crop demand, agricultural practices, and economic conditions. In recent years, there has been a growing emphasis on sustainable practices, leading some regions to reduce fertilizer use to mitigate environmental impacts.
