[QUOTE="AHDB Cereals and Oilseeds, post: 8135948, member: 142623"] High input costs are front and foremost of growers minds. UK produced Ammonium Nitrate (AN) increased 182% between Jun-21 and Mar-22, to a price of £839.00/t. With the outlook for natural gas prices (the feed stock for AN) well supported, driven by the war in Ukraine, it is well to assume that fertiliser prices could stay strong for the foreseeable future. With high input costs, we may well see a shift in fertiliser use this season and next, or potentially an impact in planted area for those crops which are more input intensive. Last Friday, Mark explored different nitrogen application strategies. These highlighted the economic impact to the grower of either applying fertiliser as per the recommended economic amount, or reducing it by either 25% or 50% this season. The results of this can be found [URL='https://ahdb.org.uk/news/nitrogen-fertiliser-application-strategies-explored-grain-market-daily']here[/URL]. This week, I look at what these scenario outcomes could equate to for UK production overall. [HEADING=1]The scenarios[/HEADING] The below tables outline the scenarios put forward and the predicted impact on crop yields. For production impacts, I have taken three of these scenario’s: [LIST] [*]Applying at the usual recommended amount for 2022 [*]Applying 75% of the typical application rate for 2022 [*]Applying 50% of the typical application rate for 2022 [/LIST] [IMG alt="Table showing fertiliser application scenarios"]https://projectblue.blob.core.windows.net/media/Default/Market%20Intelligence/cereals-oilseeds/Grain%20Market%20Daily/2022/05.%20May/13%2005%202022/Scenarios%2013%2005%202022.png[/IMG] [IMG alt="Table showing yield impact of fertiliser application"]https://projectblue.blob.core.windows.net/media/Default/Market%20Intelligence/cereals-oilseeds/Grain%20Market%20Daily/2022/05.%20May/13%2005%202022/Crop%20yield%20impact%2013%2005%202022.png[/IMG] 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. [HEADING=1]The results[/HEADING] Using the area’s forecast from the [URL='https://ahdb.org.uk/cereals-oilseeds/early-bird-survey']AHDB’s Early Bird Survey[/URL], against the 5-year average Defra yield, winter wheat production could increase this year to c.14.4Mt. This would be an increase of just under 400Kt on the year. However, should we see nitrogen fertiliser application rates drop by 50%, production could potentially be 11% less than the BAU scenario. This is purely driven by the yield impact as a result of reduced fertiliser application, and does not take into account macro factors, such as weather. By reducing fertiliser applications by only 25%, unsurprisingly the yield impact is less, but potential production could still reduce by 5%. We know that, as at the end of April, 83% [URL='https://ahdb.org.uk/cereals-oilseeds/crop-development-report']of the winter wheat crop was rated “good-excellent”.[/URL] However, rain was needed to fulfil it’s full yield potential and May has been dry to date. [IMG alt="Table showing production impact on fertiliser application"]https://projectblue.blob.core.windows.net/media/Default/Market%20Intelligence/cereals-oilseeds/Grain%20Market%20Daily/2022/05.%20May/13%2005%202022/Production%2013%2005%202022.png[/IMG] A fertiliser reduction strategy has less of an impact on the barley output, with only spring barley crops being affected. Applying nitrogen at 50% BAU levels could see UK spring barley production back 3%, but just reduced by 1% should 75% of intended nitrogen fertiliser be used instead. Oilseed rape sees a larger fall in potential production if fertiliser is reduced by 50%. Given that the planted area is forecast to be the second lowest this century, and the tight balance sheet both globally and domestically being felt for the crop, any downward revision to production is going to exacerbate this situation.
