Efficient use of fertiliser more important than ever

  • Fertiliser prices are forecast to stay high (global urea still 50–70% above 2019–2020 averages) with no major relief expected from energy or shipping costs.
  • The rand is likely to remain volatile or weaker, pushing imported nutrient prices up further.
  • Climate models predict another strong chance of La Niña-type conditions in 2026/27, bringing patchy rainfall and higher risk of nutrient leaching or denitrification.
  • Carbon border taxes (EU CBAM fully phased in by 2026) and retailer sustainability demands will penalise high-nitrogen footprints.
  • Interest rates, although possibly lower, will still make every wasted rand of input unforgiving.

What the winning farmers will be doing in 2026:
  • 100% soil-grid or zone sampling (5–10 ha grids now standard on top maize and wheat farms).
  • Full variable-rate application on nitrogen, phosphorus and lime using prescription maps.
  • Widespread adoption of enhanced-efficiency products (urease/nitrification inhibitors, slow-release coatings, and biologicals that routinely deliver 15–35 kg extra maize per bag of N.
  • Precision placement (strip-till, Y-drop, fertigation, foliar top-ups) to keep nutrients in the root zone.
  • Routine use of NDVI drone/satellite imagery and tissue testing to spoon-feed crops during the season.
  • Aggressive integration of legumes, cover crops and livestock manure to recycle P and K and maintain soil carbon.
The gap between the top 25% and the average farmer is already 2–4 tons/ha in maize and R15 000–R30 000/ha in gross margin. In 2026 that gap will widen dramatically because the high performers will be spending 20–40% less on fertiliser while harvesting the same or more.Bottom line for 2026: If you’re still broadcasting the same amount of fertiliser you used in 2020, you are effectively handed your neighbour a massive cost advantage. Efficiency isn’t optional anymore; it’s the new battleground.
