- Nearby UK feed wheat futures moved up £10.75/t yesterday, closing at £340.25/t, a contract high. The new crop (Nov-22) contract also up £12.60/t on the day before, closing the session at £315.30/t. Both contracts mirrored Paris milling wheat futures.
- The above contracts gained support on news that French winter cereal crop conditions are easing slightly, due to the hot and dry April weather. This morning, France AgriMer have estimated 89% of the French soft wheat crop in good/excellent condition, down from 91% the week earlier.
- The Ukrainian grain trader’s union (UGA) have reported this morning that 6.1Mha of spring grains has been planted in Ukraine as at 5 May. Maize and sunflower is dominating this area. The union has pegged this year’s spring cropping area at 11.45Mha, 3.5-4Mha less than a year earlier due to the war.
- Natural gas prices continue to show a strong carry in futures markets. Q4 ICE natural gas futures are trading at 242p/therm, compared to July prices at 184p/therm. We know from historical relationships that natural gas prices are very strongly correlated to fertiliser prices, and so a strong forward market for gas may point to increased costs of production for ammonium nitrate this autumn.
Nitrogen fertiliser application strategies explored
It's been a challenging time for growers wondering what to do around their fertiliser buying and application strategies off the back of higher prices over the last few months. However, using one of AHDB’s virtual farm models, analysis of the most common approaches shows that you won’t go far wrong with any of them.
Five scenarios were explored based on three main approaches:
- applying at the usual economic recommended amount in 2022 and 2023,
- apply 75% of the typical application rate each harvest year 2022 and 2023
- using July 2021 and 2022 fertiliser prices or
- using November 2021 and 2022 fertiliser prices
- apply 50% of the typical application rate each harvest year 2022 and 2023
- using July 2021 fertiliser prices or
- using November 2021 fertiliser prices
The virtual farm crops 428ha with 66% down to feed and milling winter wheats, 8.5% winter beans, 7% winter oilseed rape and 18.5% spring feed barley. The analysis used this rotation to examine five potential nitrogen (N) fertiliser strategies.
Results were calculated as total crop output minus total fertiliser cost – margin over fertiliser. The figures also took into account the impact on yields and futures prices of grains and oilseeds.
Yields were predicted to fall 2% under the economic optimum for winter feed wheat compared to 11% if AN (ammonium nitrate) fertiliser was applied at half rate. For winter rape this was a decline of 3% under the economic optimum and a fall of 9% if AN applied at 50% of the typical amount.
When averaged over 2022 and 2023 harvest years there was no real difference between the margins over fertiliser for the three scenarios where AN fertiliser was bought on July 21. Between £1,871 to £1,885/ha. The highest margin being due to higher use of N fertiliser in OSR and barley and hence less impact on yields. It was no surprise that scenarios 2b and 3 b's margins at £1,814 and £1,769/ha respectively were lower if fertiliser was bought at the higher prices in November 2021.
The right strategy will depend on the attitude to risk to yields and where you feel fertiliser and grain prices will go over the next 18 months or so. However, according to this scenario analysis, there is no significant difference between these expected common approaches. So whether fertiliser was purchased before the higher prices of late or not, some judicious reduction in application rates will pay off.
