Assuming some prices lets looks at possible margins over N fertiliser costs:

2021: Wheat £150/t; AN £250/t; BER 5; N rate 200kg N/ha; yield 10t/ha; Margin over N = £1327/ha
2022: Wheat £200/t; AN £600/t; BER 10; N rate 150kg N/ha; yield 9.7t/ha; Margin over N = £1630/ha
2023: Wheat £300/t; AN £1000/t; BER 11; N rate 140kg N/ha; yield 9.5t/ha; Margin over N = £2330/ha
