UK Farming Acronyms — A practical glossary for British farmers. The schemes, grading codes, units and acronyms that turn up on price boards, in Defra paperwork, and across the trade press — written for working farmers, not lobbyists. Updated May 2026.

Schemes and bodies — UK Farming Acronyms
Defra — Department for Environment, Food & Rural Affairs. The UK government department responsible for agricultural policy in England. Note the stylization: official UK government style is “Defra”, not “Defra”. The devolved nations have their own equivalents.
AHDB — Agriculture and Horticulture Development Board. The statutory levy body for British farming. Publishes the daily and weekly price reports most market tickers quote.
NFU — National Farmers’ Union. The largest membership body for farmers in England and Wales. The NFU lobbies government and publishes positions on policy changes.
RPA — Rural Payments Agency. The executive agency under Defra that administers EU and UK farm payment schemes. Where SFI, Capital Grants and Countryside Stewardship money actually comes from.
SFI — Sustainable Farming Incentive. The flagship environmental land management (ELM) scheme replacing Basic Payment Scheme (BPS). Open to farmers in England with annual actions you opt into.
CS / Countryside Stewardship — A longer-term environmental scheme for hedgerows, woodland, water and habitat creation. Runs alongside SFI.
BPS — Basic Payment Scheme. The legacy area-based EU subsidy. Being phased out in England through delinked payments.
FFCS — Farming for Carbon and Nature Scheme (Northern Ireland’s ELM-equivalent). The Welsh equivalent is the Sustainable Farming Scheme (SFS). Scotland operates under SFAI / the Bute House Agreement framework.
Cattle grades
R4L — A specific grading on the EUROP conformation × fat-class grid. R = “Good” conformation (out of S, E, U, R, O, P); 4L = fat class 4, low end of the range. R4L is the AHDB reference price for deadweight beef cattle — the “benchmark” carcase used in weekly price reports.
U / R / O / P — EUROP conformation classes, S being the best (Superior), P being the worst (Poor). Most prime British beef sits at U or R.
Fat classes — 1 (very lean) through 5 (very fat). Each split into H (high) and L (low). Class 3 and 4L are the commercial sweet spot for most processors.
Sheep grades and prices
SQQ — Standard Quality Quotation. The benchmark sheep liveweight price used by AHDB and most marts. Calculated from the middle range of grades sold on auction — excludes the very best and very worst. The price you’ll see on every weekly report.
NSQQ — New Season Quality Quotation. Same as SQQ but for the current season’s lambs once they enter the trade (typically late spring onwards).
Dairy units
ppl — pence per litre. The standard unit for milk farm-gate prices. UK average farm-gate milk price is typically reported as a ppl figure.
Constituents — butterfat and protein percentages, the two main quality measures milk processors pay premiums or apply penalties on.
Arable
OSR — Oilseed Rape. Brassica napus. The third largest UK arable crop by area behind wheat and barley.
WW / SW — Winter Wheat / Spring Wheat. Sown in autumn vs sown in spring. Most UK milling and feed wheat is WW.
WB / SB — Winter Barley / Spring Barley. SB is the malting-quality benchmark; WB is mostly grown as feed.
RB209 — The Defra Fertiliser Manual, published by AHDB. The reference document for nitrogen, phosphate, potash and lime recommendations across UK soils and crops. If a Defra inspector or an agronomist mentions “RB209 rates”, they mean this.
SNS / SMN — Soil Nitrogen Supply / Soil Mineral Nitrogen. The measured nitrogen available in the soil before you apply fertiliser. Used in RB209 calculations.
Environment and audit
NVZ — Nitrate Vulnerable Zone. Land designated as at risk of nitrate pollution; subject to additional nutrient management rules under the Nitrates Directive.
SSSI — Site of Special Scientific Interest. Land protected by statute for biological or geological importance. Special rules apply if your holding includes one.
EIA Agriculture — Environmental Impact Assessment (Agriculture) Regulations. Apply when you change land use on uncultivated or semi-natural land. You need EIA screening before breaking ground.
SBI / CPH — Single Business Identifier / County Parish Holding. The two reference numbers every English holding has on RPA records. You’ll need both to apply for any grant.
Bodies you’ll see cited
APHA — Animal and Plant Health Agency. The agency that handles TB testing, disease outbreaks and livestock movement records.
FSA — Food Standards Agency. The regulator behind abattoir and food-safety inspection.
Met Office — The UK national weather service. The source for the regional weather forecasts on this site’s ticker.
How we use these on BritFarmers
Throughout the paper we follow UK government style: Defra (not Defra), AHDB, NFU, gov.uk. Acronyms are defined on first use within each guide, and we link back to this page wherever a code appears that might trip up a reader who’s new to the trade.
If there’s a term you’d like added to this glossary, email hello@britfarmers.com — Tim.
