The changes facing arable farmers can sometimes feel bewildering.
In 2020 they harvested the smallest British wheat crop in 40 years, while oilseed rape, a mainstay of rotations for decades, failed again on many farms, with sugar yields also damaged.
On the political front, Brexit means the UK has its own farm policy for the first time in 45 years and new customs rules have been introduced for trade between the UK and EU.
On top of that, Covid-19 has altered consumption, changed the way business is done and impacted on the economy.
Consultants Andersons was established in 1973 when the UK entered the predecessor to the European Union.
Since then, it has analysed and assessed the prospects for British agriculture.
It highlights the change facing farmers in its Outlook 2021 report.
The failure to plant winter wheat in late 2019 had a major impact on many combinable crop businesses, but growers who were able to harvest a good crop and did not sell early are enjoying high prices.
Another failure of OSR for many growers means the crop will now be absent from their rotations.
A decade ago 750,000 hectares of oilseed rape was grown; the 2020/ 21 area is only a little more than a half of that.
The absence of OSR not only leaves a hole in rotations but in bank accounts too.
It has been the main break crop for more than 30 years and most alternatives deliver gross margins that are £250 to £245/ ha less, according to Andersons.
Oats, pulses and linseed may fill the gap in some rotations, but others will grow cereals for longer.
On heavy land, a break crop, two wheat crops followed by barley may become a new standard, while others may be tempted to grow continuous wheat or other cereals, something they can now do because they are no longer subject to the EU’s three-crop rule.
The problems with winter crops over the last few years have lead more growers to spring cropping.
For some, the inclusion of more spring crops in rotations could be beneficial, helping to flatten work peaks and reduce machinery and labour costs.
For growers with poor land an even more radical approach may be worth considering, says Andersons.
Whole-field stewardship options as part of the English Countryside Stewardship scheme give support to introduce a two-year legume fallow into the rotation.
Growers need to commit to the strategy for five years, but it will potentially be rolled over into the Environmental Land Management scheme.
Matching machinery costs to the needs of such a new enterprise is essential if the option is to be a financial success.
