One of the far-reaching global consequences of the U.S.\/Israeli war on Iran is an interruption in the world market for fossil fuel-based fertilizers that conventional farming systems depend on. <\/p>\n\n\n\n

The Strait of Hormuz\u2014which has been essentially cut off to freight transportation due to security concerns\u2014has become a choke point not only for crude oil and natural gas but also for the urea and ammonia needed to produce synthetic fertilizers. It has been widely reported1<\/a><\/sup>,<\/sup>2<\/a><\/sup>3<\/a><\/sup>,3<\/sup> that nearly 49% of global urea exports and about 30% of global ammonia exports from countries such as Qatar, Egypt, Iran, Oman and Saudi Arabia move through the Strait annually. Additionally, Iran is home to some of the world\u2019s largest natural gas reserves, a critical element of ammonia production. And finally, the Middle East provides about one quarter of the world\u2019s supply of sulfur, an ingredient in phosphate fertilizers. <\/p>\n\n\n

Impacts on Farmers and Food Systems<\/h3>\n\n\n\n

The timing couldn\u2019t be worse for many American farmers who are starting spring planting. Researchers at North Dakota State University report<\/a> that fertilizer prices spiked 23% in the first three weeks of the war, combined with sudden decreases in availability. Fertilizer sales operate in a global marketplace, so even when limited supplies directly impact some countries, the effect on prices and availability ripples throughout the entire industry. The North Dakota economists note that \u201cfertilizer prices often continue to rise for several months after the initial disruption, particularly when supply chains remain constrained.\u201d<\/p>\n\n\n\n

Some farmers may try to stretch their fertilizer budget, risking yield losses. Others may pivot to crops that require less fertilizer. And for some who have been hanging on year after year, this may be the tipping point to make the painful decision to sell the family farm.<\/p>\n\n\n\n

As crop production costs rise and yields drop, the impact will trickle down to consumers in the form of higher grocery prices. As always, small producers and economically vulnerable communities will be disproportionately impacted. A recent story in The Guardian lays out the global implications in a column titled \u201cEnergy shock talk grabs headlines but the Iran war is also driving the world towards a food crisis<\/a>.\u201d<\/p>\n\n\n\n

This is not the first time in recent years that a shock like this has hit the agriculture industry. In the fall of 2023, the U.S. Economic Research Service reported<\/a> on the one-two punch caused by the Covid-19 pandemic followed by Russia\u2019s invasion of Ukraine in 2022. That war caused a short-term transportation interruption in the Black Sea region, briefly driving up fertilizer prices by 50%, and longer-term issues stemming from war-related trade restrictions. At the time, Russia and Belarus exported almost 20% of the world\u2019s fertilizers.<\/p>\n\n\n\n

The Trump administration and members of Congress have floated various proposals in response to this crisis including military escorts for freighters, shoring up domestic fertilizer production infrastructure, a bill<\/a> requiring transparent reporting on fertilizer pricing, and financial bailouts for farmers.<\/p>\n\n\n\n

Policymakers have another option: <\/strong>Support farmers in reducing their reliance on synthetic fertilizer by making alternatives more economical and accessible.<\/p>\n\n\n\n

Soil Health as a Long-Term Solution<\/h3>\n\n\n

For many years, the USDA Natural Resources Conservation Service<\/a> (NRCS) has been a leader in supporting farmers with building soil health, which they define as \u201cthe continued capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans.\u201d NRCS describes four principles of soil health that can be realized by using practices such as composting and mulching, planting cover crops, reduced tillage, conservation plantings, diverse rotations, prescribed grazing, and others. <\/p>\n\n\n\n

Adopting these practices is not simply a matter of replacing fossil fuel-based fertilizers with a different input\u2014the transition requires new products and input suppliers, equipment and knowledge, as well as changes to existing policies and regulations. Policymakers have a key role to play here by supporting research and development, incentives and technical assistance, and streamlining regulations to reward farmers for adopting multi-benefit practices.<\/p>\n\n\n\n

Recognizing a federal role for assisting farmers with continually improving on-farm environmental stewardship, the NRCS provides grants for agricultural conservation practices through their Environmental Quality Incentives Program<\/a> y Conservation Stewardship Program<\/a>, both of which have historically large amounts of funding available over the next few years. With some of this increased funding, NRCS also recently launched a Regenerative Agriculture pilot program<\/a> that has a focus on grants for soil health practices. <\/p>\n\n\n\n

The state of California and several others around the country have also created healthy soils programs with similar goals (read about some of these efforts on CDFA\u2019s website<\/a> and on the Red Nacional de Pol\u00edtica de Suelos Saludables<\/a> website). California\u2019s Alternative Manure Management Program (AMMP<\/a>) provides grants to dairy farmers to produce compost from their manure as an organic fertilizer. At CalCAN, we are champions of a federal bill (the Ley COWS<\/a>), sponsored by Rep. Jim Costa, to replicate this program at the USDA.<\/p>\n\n\n\n

Governments can also make it easier for farmers to adopt soil building techniques by minimizing regulatory red tape. For example, California\u2019s Irrigated Lands Regulatory Program (ILRP), which attempts to reduce nitrate contamination in groundwater caused by excess fertilizer, could encourage the use of alternatives to synthetic fertilizers such as compost and cover crops. To scale up the production of much-needed compost from dairy operations, the state could create an efficient and effective process for approving new on-farm composting projects on livestock operations, as proposed in the CalCAN-sponsored bill AB 2100<\/a> (Connolly).<\/p>\n\n\n\n

The co-benefits that come with a focus on soil health are many, including:<\/p>\n\n\n\n
