Precision Strategies for Managing High Urea Prices and Supply Risks

A perfect storm for fertiliser markets

Farmers around the world are facing a fertiliser market squeezed by geopolitics and supply constraints. The escalation of conflict in the Middle East in early 2026 closed the Strait of Hormuz, shutting fertiliser plants and disrupting shipping routes. Reuters reports that urea prices at the New Orleans import hub jumped from about $516 per metric ton to as much as $683, and analysts warned that prices could climb even higher if the closure persists[1]. The article notes that fertiliser shipments through the strait make up roughly one-third of global trade, and the shutdown came just as farmers needed urea for spring planting[1]. With supply tight, some Indian plants have already cut urea output[2].

High fertiliser prices are not solely due to war. Farm Progress explains that natural gas is a major input for nitrogen fertilisers, so increases in gas prices push up the cost of ammonia and urea[3]. In addition, China has restricted exports of urea and other fertilisers to ensure domestic supply, further tightening the market[4]. Together these factors have created a volatile and expensive fertiliser landscape, leaving growers searching for ways to economise without sacrificing yields.

Precision agriculture: an antidote to high urea prices

Soil testing and deep soil sampling

When urea is expensive or hard to source, the first step is to know how much nitrogen your soil already contains. Dawson Agriculture emphasises that soil is the foundation of every cropping and fertiliser decision, especially with rising input costs[5]. Deep soil testing can uncover residual nitrogen in the profile. Research cited by Texas A&M’s AgriLife Extension found that deep soil sampling before planting corn, cotton or wheat can save $13-$189 per acre by accounting for existing nitrogen[6]. In some cases, savings across a 1,000-acre farm can exceed $30,000 and reach more than $130,000 when residual nitrogen meets 100% of crop requirements[7]. Such savings become critical when urea prices are high.

NDVI and variable rate applications

NDVI imagery allows farmers to see where crops are thriving and where they struggle. FieldBee describes how NDVI measures differences between near-infrared and visible light; higher values signal healthy crops, while lower values suggest stress[8]. Variable Rate Application (VRA) technology uses this data to apply inputs precisely where needed, optimising fertiliser use and improving yields[9][10]. By targeting nitrogen only to zones with low NDVI and adequate soil capacity, growers can stretch limited urea supplies further.

EM surveys and zone management

Electromagnetic surveys map soil texture, moisture and salinity. GRDC notes that EM readings reflect soil texture and moisture, and that dual-depth surveys can detect variability down to 50 cm and 1.5 m[11]. Dawson Agriculture’s zonal soil testing uses NDVI or EM data to subdivide paddocks into zones for sampling and variable-rate fertiliser plans[12]. When urea is expensive, allocating nitrogen to zones with low organic matter or poor moisture retention while reducing rates on healthier zones can maintain yield while cutting total nitrogen use.

Crop choices and alternative fertilisers

High nitrogen prices may also influence crop selection and fertiliser sources. Reuters notes that some analysts expect farmers to cut back on corn, which is nitrogen-intensive, or to reduce application rates[13]. Crops like legumes that fix nitrogen or require less urea may become more attractive. Exploring alternative fertilisers (such as controlled-release products or manure) and timing purchases to lock in lower prices are strategies many farmers already use.

Take control of your nitrogen bill

The combination of geopolitical risk, energy costs and export restrictions has made urea both expensive and potentially scarce. Precision agriculture tools provide a way to control input costs: soil testing identifies existing nutrients, NDVI and EM data drive variable-rate decisions, and deep sampling quantifies residual nitrogen. By tailoring fertiliser rates to actual crop and soil needs, growers can maintain productivity and environmental stewardship even in the face of soaring urea prices.
