It might sound niche that there is a global fertiliser crisis upon us, but the ramifications of this could be huge.
Prices for fertiliser in the UK doubled earlier this year, then doubled again. Similar, if not quite as severe, price rises hit globally as well, including countries in Europe and America.
And then gas prices surged in Europe, with the UK most impacted again.
* The UK's problems due specifically to government policy - 1) allowing Centrica to close, for profit maximisation reasons, 70% of the UK's gas storage capacity, which helps smooth wholesale price bumps; and 2) Brexit zealotry, where the govt withdrew from the Internal Energy Market as part of its wildly dogmatic opposition to any EU institution, despite not having to do so as the IEM allows non-EU members (like Norway and Switzerland).
Almost all production of nitrogen-based fertilizer relies on the use of natural gas. Fertiliser producers slowed production earlier in the year to use up stockpiles (produced when gas was cheaper) with the aim of ramping up production again when gas prices fell back. But gas prices continued to rise and in September, the UK saw its two fertiliser production plants close, citing the astronomical wholesale gas prices.
Some farmers did buy when prices rose earlier in the year; many didn't. And once production stopped, farmers began to panic buy and fertiliser soon became next to impossible to get hold of. Those farmers who bought in the summer are having to keep it [literally in some cases] under armed guard.
The situation isn't actually that much better in Europe. Lithuania is a major producer of fertiliser and, like all countries, has scaled back production. China has blocked exports of fertiliser to keep them for its own agriculture needs. The US is less impacted by shortages, but prices has risen sharply there as well.
Some farmers have reverted to using sewage-based fertiliser to autumn-feed their land, but there's restrictions on this, and they cannot use this method for spring-fertilising where the land will be used for food crops.
Modern farming is dependent on nitrogen-based fertiliser. Crops have been 'modified' to give higher yields - but need fertiliser to, in many cases, even survive. To give an idea of broad average grain yields using various methods:
No fertiliser - 0.5 t/acre
Animal manure - 1.5 t/acre
Natural strains with fertiliser - 4.0 t/acre
Improved strains with fertiliser & pesticides - 7.0 t/acre
Even if full production of fertiliser were to begin tomorrow, to produce enough fertiliser to meet demand will take 3-5 months. That won't be sufficient time for all farmers to fertilise in time for the spring fertilising season in late winter/early spring, and a lot of land will have had no autumn feed.
In the developed world, severe food price rises for 2022 are already baked in. It will create increased hardship for millions.
But the main problems will be in the developing world. The rarer supplies of fertiliser will be hoovered up by the richer developed world. Any country lucky enough to have food surpluses next year will see them selling for a much higher price to the developed world. That leaves the billions living in the developing world facing famine and starvation.
