Comply with farming environmental regulations

Understanding your obligations

Environmental farming regulations come from multiple sources:

• Statutory requirements: Legal obligations that apply to all farmers, regardless of whether you receive subsidies (e.g., water pollution prevention, pesticide regulations)
• Nitrate Vulnerable Zone (NVZ) rules: Stricter requirements in designated NVZ areas covering about 55% of land in England
• Scheme agreement terms: Conditions you accept when you enter SFI, Countryside Stewardship, or other agri-environment agreements - breaches can lead to payment recovery or termination
• Environmental permit requirements: Specific permits needed for certain activities (e.g., large pig/poultry units, slurry spreading near watercourses)

The Environment Agency and Rural Payments Agency enforce these regulations through inspections.

Fertiliser and manure storage and application

Preventing water pollution from fertilisers and organic manures is a fundamental legal requirement that applies to all farms.

Slurry storage capacity requirements

The SSAFO baseline is 4 months' storage capacity. In NVZs you need 5 months for cattle slurry (covering 1 October to 1 March) and 6 months for pig and poultry slurry (covering 1 October to 1 April). Your requirement is calculated from your livestock numbers and housing periods. To calculate your required capacity:

• Estimate daily slurry production per animal (varies by livestock type and diet - guidance tables in RB209)
• Multiply by number of housed animals and number of days housed
• Add 10% for rainfall and washings
• Ensure your store(s) can hold this volume without risk of overflow

If your storage is inadequate, you risk prosecution for pollution incidents during wet winters when you cannot spread. The Slurry Infrastructure Grant can help fund new storage to meet requirements (see farming grants guide).

Application timing and weather restrictions

The prohibition on applying to waterlogged, flooded, frozen, or snow-covered ground is strictly enforced. Environment Agency officers patrol during wet weather looking for inappropriate spreading. If caught:

• Immediate notice to stop spreading
• Formal warning or caution
• Prosecution if pollution occurs (unlimited fines)
• Possible recovery or termination of agri-environment scheme payments under your agreement terms
• Requirement to take remedial action at your expense

The defence "I had to empty the store because it was full" is not accepted. Inadequate storage is your responsibility, not a valid excuse for polluting.

Pesticide application and certification

Using pesticides professionally requires proper certification, equipment testing, and record-keeping.

Obtaining PA1 and PA2 certificates

The PA (Pesticide Application) certificates are awarded by City & Guilds NPTC (National Proficiency Tests Council) following training and assessment:

• PA1 Foundation Module: Covers pesticide safety, environmental protection, legal requirements. Usually 1 day training + assessment
• PA2 Ground Crop Spraying: Practical skills for operating boom sprayers, calibration, nozzle selection. Usually 2-3 days training + practical assessment

Find approved training providers through the National Register of Sprayer Operators (NRoSO) or City & Guilds. Costs typically £600-£1,000 for combined PA1/PA2 training and assessment.

Once qualified, your certificates are valid for life. However, if you want to join BASIS professional registers or certain assurance schemes, you'll need to undertake Continuing Professional Development (CPD).

National Sprayer Testing Scheme (NSTS)

All agricultural spraying equipment used professionally must be tested within 5 years of purchase, then every 3 years thereafter. This includes:

• Tractor-mounted boom sprayers
• Self-propelled sprayers
• Granular applicators

Exempt equipment: Knapsack and other hand-held sprayers are exempt from formal NSTS testing - carry out regular self-checks instead. CDA applicators and hand-held trigger sprayers for spot treatment are also exempt.

Book testing through an authorised NSTS testing organisation. Testing costs £100-£300 depending on sprayer type and complexity. If your sprayer fails, you must repair defects and retest before further use.

Pesticide application records

You must keep records of every pesticide application for at least 3 years. Required information includes:

• Date of application
• Crop or target treated and specific field location
• Pesticide product name and active ingredient
• Dose rate applied (e.g., litres per hectare)
• Total area treated
• Name of operator who applied the pesticide
• Weather conditions (wind speed, temperature, rainfall forecast)

Records can be paper-based or electronic (farm software). Inspectors from Health & Safety Executive, Environment Agency, or trading standards can request to see records during farm visits.

What replaced cross-compliance

Cross-compliance ended in England on 31 December 2023, when Basic Payment Scheme payments were delinked. There is no GAEC or SMR "conditionality" regime in England. Your environmental obligations now come from two places: domestic baseline law, and the terms of any scheme agreements you hold.

Baseline law that applies to every farm

The protections that previously sat behind cross-compliance now apply directly through domestic legislation, whether or not you receive payments:

• Farming Rules for Water: The 8 rules on nutrient planning, application, and soil management that apply to all farms in England (see our dedicated guide)
• NVZ rules: Closed periods, nitrogen limits, and storage requirements if your land is in a Nitrate Vulnerable Zone
• Management of Hedgerows (England) Regulations 2024: In force since 23 May 2024. Maintain a 2-metre buffer strip measured from the centre of each hedgerow, with no cultivation and no fertiliser or pesticide application within it, and do not cut or trim hedgerows between 1 March and 31 August (limited exceptions and Rural Payments Agency derogations apply). The RPA enforces these rules with civil sanctions
• Environmental permits and SSAFO: Permit requirements for large pig and poultry units, and construction standards for silage, slurry, and fuel oil storage
• Animal identification and welfare law: Livestock identification, movement, and welfare requirements continue to apply directly

Scheme agreement terms

If you hold a Sustainable Farming Incentive, Countryside Stewardship, or other agri-environment agreement, its terms are conditions of payment. The RPA takes an advice-led approach to breaches, but can recover payments already made or terminate your agreement. There is no percentage-reduction penalty matrix - the old 1-5% cross-compliance deductions no longer exist.

Nutrient management planning

Nutrient management planning ensures you apply the right amount of fertiliser at the right time, reducing costs and environmental impacts.

Creating a nutrient management plan

A nutrient management plan calculates crop nutrient requirements and plans fertiliser applications to meet those needs without excess. The process involves:

Step 1: Soil testing

Take soil samples from each field (or management zones within large fields) every 3-5 years. Standard soil analysis measures:

• pH (soil acidity/alkalinity)
• Phosphorus (P) index (0-9 scale)
• Potassium (K) index (0-6 scale)
• Magnesium (Mg) index (0-6 scale)

Use a UKAS-accredited laboratory. Costs are typically £10-£20 per sample. Most farms need 1 sample per 5 hectares for representative results.

Step 2: Calculate crop requirements

Use RB209 (The Fertiliser Manual) tables to determine nutrient requirements for your intended crops. Requirements vary based on:

• Crop type and realistic yield expectation
• Soil nutrient indices from your soil tests
• Previous cropping (e.g., grass/legume residues provide nitrogen)
• Organic manure applications planned

Step 3: Account for organic manures

If you apply slurry, farmyard manure, or other organic materials, calculate their nutrient content using RB209 or laboratory analysis. This nutrient supply must be deducted from manufactured fertiliser requirements.

Many farmers over-apply manufactured fertiliser because they underestimate manure nutrient value. Accurate accounting saves money and reduces environmental risk.

Step 4: Plan application timing

Split nitrogen applications to match crop demand through the growing season. Avoid autumn applications on bare soil (high leaching risk) and time spring applications to coincide with rapid crop growth.

Using nutrient management software

Free and commercial software tools simplify nutrient planning:

• PLANET (Planning Land Applications of Nutrients): Free software from AHDB implementing RB209 calculations. Widely used and accepted by regulators
• MANNER-NPK: Free tool calculating manure nutrient availability based on application method and timing
• Commercial farm software: Many farm management systems (Muddy Boots, Gatekeeper, Farmbench) include nutrient planning modules

Regulators expect to see documented nutrient plans if you're in an NVZ or claiming to follow Integrated Farm Management practices. Software-generated plans provide professional documentation.

Nitrate Vulnerable Zones

If your land is in a Nitrate Vulnerable Zone, you face additional restrictions on fertiliser and manure application timing, quantities, and storage. These are enforced by the Environment Agency.

See our dedicated NVZ compliance guide for full details on nitrogen limits, closed periods, storage requirements, and record-keeping obligations.

Water pollution incidents - what happens

Despite best efforts, pollution incidents sometimes occur. Understanding the process helps you respond appropriately:

If a pollution incident occurs

• Stop the source immediately: Block drains, stop spreading, isolate leaking tanks
• Report to Environment Agency: Call 0800 80 70 60 (24-hour incident hotline) even if you caused it - early reporting is viewed more favourably
• Take remedial action: Use straw bales, sandbags, booms to contain pollution. Pump contaminated water to tanks if possible
• Document everything: Photographs, witness details, weather conditions, actions taken
• Cooperate with investigation: Environment Agency officers will investigate. Full cooperation improves outcome

Potential outcomes

• Advice and warning: Minor incidents with prompt action may result in written warning and improvement advice
• Formal caution: More serious incidents may receive formal caution with conditions
• Prosecution: Serious or repeated incidents can be prosecuted, carrying severe penalties including a criminal record
• Remediation costs: You may be billed for EA clean-up actions (fish rescue, water treatment, monitoring)
• Civil claims: Water companies, fisheries, or downstream landowners may sue for damages
