Comply with farming environmental regulations
How to comply with environmental regulations for fertiliser storage and application, pesticide use, cross-compliance standards, and nutrient management planning. Covers Nitrate Vulnerable Zones, BASIS certification, GAEC standards, and RB209 nutrient planning.
All farmers must comply with environmental regulations designed to protect water quality, soil health, biodiversity, and public health. These regulations apply regardless of whether you receive government payments, though payment schemes have additional conditionality requirements.
Environmental compliance covers how you store and apply fertilisers and manures, use pesticides, protect landscape features, and manage nutrients. Breaching these regulations can result in prosecution, fines, cross-compliance penalties affecting subsidy payments, and restrictions on your farm operations.
This guide explains the key environmental compliance requirements for farms in England.
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
- Cross-compliance/Conditionality: Additional standards you must meet to receive SFI, Countryside Stewardship, or other agri-environment payments
- 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, often coordinated with cross-compliance checks.
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 requirement for 5 months' storage capacity (6 months in NVZs) is calculated based on 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)
- Cross-compliance penalty reducing subsidy payments by 1-5% or more
- 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
- Handheld knapsack sprayers used commercially
Exempt equipment: Knapsack sprayers used only by the certificate holder on their own land, CDA applicators, hand-held trigger sprayers for spot treatment.
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.
Cross-compliance and conditionality
If you receive payments under Sustainable Farming Incentive, Countryside Stewardship, or other agri-environment schemes, you must meet conditionality standards. These replaced cross-compliance from January 2024.
Understanding GAEC standards
Good Agricultural and Environmental Condition (GAEC) standards are designed to maintain land in good condition and protect environmental features. Key GAEC standards include:
GAEC 1: Watercourse buffer strips
You must maintain 2-metre buffer strips alongside all watercourses (rivers, streams, ditches, lakes, ponds). Within the buffer:
- No fertiliser or pesticide application
- No cultivation
- Permanent vegetation cover maintained
This is the most commonly breached GAEC standard. Satellite monitoring detects buffer strip breaches automatically, triggering inspections and penalties.
GAEC 6: Minimum soil cover
At least 70% of your arable land must have soil cover during winter (December-February). Acceptable soil cover includes:
- Over-wintered crops (winter cereals, oil seed rape)
- Cover crops (mustard, rye, vetch, etc.)
- Post-harvest residues left on the surface
- Rough seedbed prepared in autumn
Bare cultivated soil over winter increases erosion and nutrient loss. If you have large areas of spring cropping, plan cover crops or manage post-harvest residues to meet the 70% threshold.
GAEC 7: Crop rotation
On arable holdings over 10 hectares, you must either:
- Rotate crops annually (different crop from previous year on each parcel), OR
- Justify continuous monoculture based on agronomic, environmental, or climatic factors
Acceptable justifications for monoculture include specialist crops (asparagus, fruit), environmental scheme requirements, or land unsuitable for rotation. Document your justification in writing.
Statutory Management Requirements (SMRs)
SMRs cover animal welfare, public health, and plant health obligations. The most relevant to environmental compliance is SMR 1: Nitrates Directive, which requires compliance with NVZ rules if your land is in a Nitrate Vulnerable Zone.
Conditionality inspections and penalties
The Rural Payments Agency conducts risk-based conditionality inspections. If selected, inspectors will:
- Visit your farm with minimal notice (usually 48 hours)
- Check compliance with GAEC and SMR standards
- Review records (fertiliser applications, pesticide use, livestock medicines)
- Measure buffer strips, assess soil cover, inspect livestock facilities
- Use satellite imagery and mapping to verify land management
Penalties for non-compliance:
- Negligent breaches: 1-5% reduction in scheme payments
- Repeated breaches: Higher penalty percentages
- Intentional breaches: Up to 100% loss of payments plus disqualification from schemes
Penalties apply to the scheme payment year in which the breach is detected. For serious or repeated breaches, penalties may apply over multiple years.
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 (0-6 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

Practical compliance checklist
Use this checklist to audit your farm's environmental compliance status:
-
Verify slurry storage capacity meets requirements
Calculate your storage requirement based on livestock numbers and housing period. Measure your actual storage volume. If inadequate, plan to build additional capacity or reduce livestock numbers during winter. In NVZs you need 6 months minimum.
-
Check buffer strips are maintained alongside all watercourses
Walk your farm boundaries and identify all watercourses (including ditches and drains). Ensure 2-metre buffer strips have no cultivation, fertiliser application, or pesticide use. Mark buffer strips on farm maps and brief all staff/contractors.
-
Ensure all pesticide users hold valid PA1 and PA2 certificates
Check certificates for yourself and all staff who apply pesticides. If anyone needs training, book courses before the next spraying season. Display certificates in the office or secure them in the farm safety file.
-
Book NSTS sprayer testing if due within 12 months
Check last test date for all sprayers. New equipment must be tested within 5 years of purchase, then every 3 years thereafter. Book testing at least 2 months before expiry to allow time for repairs if defects are found. Using untested equipment is an offence.
-
Review and update nutrient management plan annually
Before each growing season, update your nutrient plan based on intended crops, latest soil test results, and planned manure applications. Keep dated copies of plans to demonstrate compliance during inspections.
-
Complete soil testing on schedule (every 3-5 years per field)
Maintain a soil testing schedule ensuring each field is tested at least every 5 years (3 years if in an NVZ or high-intensity system). Schedule testing in autumn after harvest for spring crop planning.
-
Maintain pesticide application records for 3 years minimum
After every pesticide application, record: date, field, product, dose rate, weather, operator name. File records in chronological order and keep for at least 3 years. Inspectors can request records at any time.
-
Check if your land is designated as NVZ
Use the GOV.UK 'Check if your land is in a nitrate vulnerable zone' tool. NVZs are updated every 4 years. If designated, ensure you comply with closed periods, nitrogen limits, and enhanced record-keeping.
