1 Environmental guidance for potato production A better environment for business

2 Foreword Environmental Guidance for Potato Production The Water Framework Directive and cross-compliance mean there are more reasons to ensure potato production is environmentally sustainable. This updated guide aims to highlight best practice in potato production, enabling growers to manage the environmental risks and maximise the opportunities of their industry. Against a backdrop of consumers who are increasingly interested in the source of their food, those who can demonstrate they are working harmoniously with the environment may find this offers greater marketing and production benefits. The updated guide covers new developments such as, Campaign for the Farmed Environment 1 and the recent changes to the Soil Protection Review 2 and Environmental Stewardship 3. The potato sector presents its own individual diffuse water pollution risks on account of soil structural issues and the use of specific pesticides and nutrients. The booklet provides guidance as to which planning-tools and management options are effective in reducing these risks, as well as signposting which options can be funded under Environmental Stewardship. The Potato Council has worked closely with FWAG and England Catchment Sensitive Farming Delivery Initiative to ensure this guide gives potato growers the practical guidance to realise the opportunities and stay within the limits of the new environmental framework. It also addresses many of issues that are being developed to ensure the potato industry is well equipped to face the challenges of the future.

3 Land selection A number of factors must be considered when selecting land for potato growing. These include a field-by-field assessment of the following: A field risk assessment of soil and water risk (see next page) The management and conservation of existing habitat The protection of archaeological features. Grassland Semi-improved grassland should not be selected for potato growing. This grassland is an extremely important habitat for a wide range of species and is becoming increasingly scarce in some parts of the UK. The UK is committed to retaining its areas of permanent pasture under EU legislation. Any ploughing of permanent pasture or semi improved grassland will require an Environmental Impact Assessment (EIA) 4. Uncropped areas Any un-cropped areas can be of high biodiversity value. Options under the Campaign for the Farmed Environment and Environmental Stewardship can be used to retain these habitats and more detail is contained in the tables at the rear of this guide. Priority should be given to maximising the biodiversity potential of: Land previously managed as long term set-aside Field margins Mid-field breaks e.g. beetle banks and wild bird cover strips Field Boundaries Hedges, walls, ditches and tracks provide excellent habitats for wildlife. The wildlife value of these boundary-features can be further enhanced by adding buffer strips. The height of hedges and frequency of cutting can be managed to provide a range of different habitats across the farm. This is to meet the nesting and feeding requirements of birdlife. Where there is a risk of wind erosion, the planting and correct maintenance of hedges can serve to mitigate this risk. Archaeology When selecting fields for growing potatoes, be aware that the site will require deeper cultivation than for other crops. This can result in the disturbance of undiscovered archaeology, where an important piece of history can be lost or irreparably damaged. Prior to undertaking any cultivation, first check the land itself for any distinguishing features which may be of archaeological interest. Other resources available to you are maps, records and local knowledge. If necessary, seek advice from a Local Authority archaeologist. A range of management options for the protection of archaeology exist within Environmental Stewardship. 3

4 Soil Management in Potato Production Soil erosion risk A Field Risk Assessment should be undertaken for each field prior to cropping with potatoes. This is to reduce the risk of run-off and erosion, which could impact upon nearby watercourses, roads, tracks or wildlife sites. Soil run off and erosion are harmful because of sedimentation of water bodies, as well as nitrates, phosphates, pesticides and other chemicals that are carried on soil particles. This can affect both water quality and biodiversity in water bodies e.g. by causing eutrophication or smothering fish spawn. The risk of soil erosion / run-off occurring will vary according to the field s soil type and slope (steepness & direction). The impact of these processes will depend on the presence of a receptor (watercourse, important habitat, road or properties). Once a field risk has been determined, then appropriate control measures can be planned. Many of these control measures feature in the SPS Cross Compliance Guidance for Soil Management (2010 edition), however additional guidance is also available from: The Environment Agency s Think Soils manual 5 Tel.: The England Catchment Sensitive Farming Delivery Initiative 6 Potato Council s Soil Management for Potatoes 7 Example Field Risk Assessment Field reference Characteristic Risk Management control Top Meadow Long uninterrupted gentle slope towards roadside gateway. Potato drills are at risk of channelling run off towards gateway and onto road. Split crop the field to reduce catchment size. Disrupt tramlines & avoid working up-and-down slope. Leave roadside headland unplanted and deep cultivate to capture any field run off. Consider moving gateway. Park field Sandy silt loam and slight slope in direction of properties. Field susceptible to capping following rainfall/irrigation. Manage cultivations to avoid creating too fine a tilth and utilise a depressional roller behind planter. Leave uncropped margin on headland adjacent to properties and deep cultivate to capture any field run off. Bottom Meadow Light sandy soil with moderate slope in direction of watercourse. Risk of run off following irrigation. Install tied ridges to capture irrigation water. Leave unplanted headland and establish a grass margin next to watercourse. Disrupt tramlines to break up flow. 4

5 Meeting Regulations Soil Protection The management of soils to reduce erosion and run off is a Cross Compliance requirement under the Single Payment Scheme (SPS). The latest editions of the Cross Compliance Guidance and Soil Protection Review (SPR) came into effect on the 1st January It is quite common for potatoes to be produced on short-term tenancy, or temporary occupation agreements. As a result, it is strongly recommended that growers refer to the Soil Protection Review, to ensure continuity of land management practices. This will avoid any potential breaches of cross compliance. In many cases, the completion of an individual Field Risk Assessment will help identify additional landmanagement control measures. If needed, this might go above and beyond the requirements of cross compliance. Nitrate Vulnerable Zones (NVZ) 8 The most recent review of the NVZ action programme requires growers to produce a nitrogen plan for potatoes produced within NVZ designated areas. They should also maintain comprehensive records of nitrates applied from organic manures and fertilisers. Potato crops are now also subject to an N Max limit of 270kg/N/ha. Agricultural Waste We currently operate under waste regulations which came into force in May These introduced a framework of licensing and other requirements for the management of on-farm waste. The regulation includes prohibiting the use of farm tips, places restrictions on the burning of wastes in the open and requires growers to abide by a Duty of Care. Waste from store At various times, growers may have potatoes which require disposal from store. The waste regulations allow for growers to register an exemption, should they wish to deposit plant material at the place of production (e.g. to rot down potatoes). This exemption will be subject to various conditions, to include the following: any potato dump is kept separate from any site where any other plant tissue waste is deposited and there is no more than 250 cubic metres (tonnes) in any one deposit; no dumping occurs on land which is frozen hard or snow-covered; waterlogged or flooded; or less than 10 m from a watercourse or 50m from a spring, well or borehole; and the disposal is carried out in accordance with any requirement of the Nitrate Vulnerable Zones Regulations More information on the management of agricultural waste including how to apply for an exemption license is available from the Environment Agency: Tel.:

6 Protecting the environment The Field Risk Assessment can be used to identify specific management measures to control the pollution risk at source, slow the pathway of a pollutant and protect the receptor, which could be damaged by the pollutant Source (Field site characteristics soil type, soil structure and slope) Pathway (Direction of planting, Tramlines, Wheelings, access tracks) Receptor (watercourse, important habitat, road or properties) Tackle the source Slow the pathway Protect the receptor Environmental Stewardship and CFE offer you the opportunity to install fixed measures over the longer term. These measures can help manage run off/erosion pathways and also buffer receptors. When multiplied across a number of farms, the adoption of these measures will potentially deliver the desired improvements on a catchment scale and reduce the need for further regulation and statutory land-management controls. The tables opposite are examples of some Environmental Stewardship and CFE options that can deliver both environmental and financial benefits on farm. 6

7 Tackling the source ELS code Option description Resource protection value ELS/OELS points CFE code EJ13/OJ13 Winter cover crops: Drill or broadcast a quick growing cover crop e.g. rye, vetch, phacelia, mustard. (Establish by 15th September and destroy late January/ early February immediately prior to establishment of spring crop Cover crops will help reduce nitrate leaching on light sandy soils. Over winter cover crops may provide protection against soil erosion and loss of pollutants carried in surface run off water. 65 per ha C7b this option may not be suitable for all farms due to ELS agreement soil type restrictions and cropping rotations. In these situations the appropriate measures outlined under the SPR or those identified under the Soil Management Plan should prevail. Pathway control ELS code Option description Resource protection value ELS/OELS points CFE code EF1/OF1 Management of field corners: Establish or maintain a tussocky grass field corner either by sowing or through natural regeneration. Trees can also be established. Strategic placement of this option may help reduce the movement of sediment, nutrients and pesticides by wind and water erosion. 400/500 per ha C7b EF7/OF7 Beetle banks: Create an earth bank between 2 4m wide, 0.4 m high and sow with a mixture of perennial and tussocky forming grasses Placed across field slopes, beetle banks can be used to reduce run-off and erosion provided that they do not channel water and exacerbate a catchment problem. 580/750 per ha EJ5/OJ5 In-field grass strips: Establish or maintain either by sowing or through natural regeneration a within field tussocky grass strip of 10 metres minimum width. Grassing natural drainage pathways (e.g. valley bottoms) will help to reduce the channelling of run-off to minimise soil wash, rills and gullies, which lead to soil, nutrient and pesticides losses. 350 per ha C2 Protecting the receptor ELS code Option description Resource protection value ELS/OELS points CFE code EE9/OE9 6 metre buffer strip on cultivated land next to a watercourse: Establish or maintain a tussocky grass field margin either by sowing or through natural regeneration. Strategic placement of this option can reduce the movement of sediment, nutrients and pesticides by wind and water erosion. 400/500 per ha EJ9/OJ9 12 metre buffer strip on cultivated land next to a watercourse: Establish or maintain a tussocky grass field margin either by sowing or through natural regeneration. Width of strip may vary from metres in width. Ideally the buffer strip will protect adjacent watercourses by intercepting and removing sediment, organic materials, nutrients and chemicals carried in run off. 400 per ha C1 7

8 Resource Management Planning Management Plans are a requirement of many production protocols and can also serve as tools of best practice. These include plans for Nutrient management, Manure management, Crop Protection and Irrigation. Implementing these plans will not only provide you with environmental benefits; they can also deliver cost savings through the more efficient usage of resources. Nutrient Management Plan Fertiliser applications should meet anticipated crop nutrient requirements, taking account of soil nutrient reserves and applied organic manures. Not only does this maximise the economic value of the crop but it also helps minimise the environmental impact. Updated in 2010, the RB209 manual 10 provides revised nutrient recommendations which are crop-specific. The recommendations for potatoes have been updated and are also included in the revised Potato Council guide Crop nutrition for potatoes. RB209 Nutrient recommendations form the basis of the nutrient-budgeting software, PLANET 3 (2010) 11. These recommendations are also incorporated into other farm-management programmes. The crop nutrient recommendations contained within RB209 can also be used in the paperbased nutrient management plan Tried & Tested 12, supported by the Industry (AIC, CLA, FWAG, LEAF and NFU) and the England Catchment Sensitive Farming Delivery Initiative (ECSFDI) PLANET and Tried & Tested are available free of charge and approved for use under the 2008 Nitrate Vulnerable Zone (NVZ) compliance programme. 8

9 Manure Management Plan Optimum organic manure applications seek to maximise nutrient capture by the crop and minimise losses to the environment. MANNER 13 is a computer software tool to calculate the availability of manure nitrogen to crop. This can be used in advance of applying manure to check the likely effect of a spreading policy using manure application details and weather data. Crop Protection Management Plan The control of pests, diseases and weeds will protect both crop yield and quality. Correct usage of pesticides should be economically viable and minimise any non-target effects on the environment. A BASIS certified adviser should be used for guidance and recommendations on pesticide use. The risk of pesticides contaminating water depends on a number of factors. These include your product choice, dose rate and drain flow. Weather conditions at both the time of spraying and after application are crucial, as is your sprayer set-up and proximity/connectivity to local water bodies. This is especially the case where there is risk of soil loss, with pesticides attached to soil particles. Irrigation / Water Management Plans Many potato crops require irrigation to maximise yield and quality. Care should be taken to ensure that water applications do not have an adverse environmental impact. Guidance based upon trials funded by levy payers on the efficient and effective use of water to support potato production is available from the Potato Council 15. The following environmental considerations should also form part of a farm water management plan: Use a recognised programme to schedule the amount and timing of irrigation applications (do not rely upon crop inspection and judgement) Manage application rates to avoid run-off and soil erosion linked to filtration capacity of different soils and slopes When spreading manures and slurries, a Manurespreading Risk Map should be prepared for each field to assess pollution risks. This determines the suitability of organic manure applications, recording relevant features such as the direction of slopes and the location of watercourses and boreholes. An example of this can be the marking of no-spread zones on a map, where risk of slurry run-off is high, and where application methods and rates will need adjusting to minimise potential losses. The Voluntary Initiative (VI) Crop Protection Management Plan 14 provides a decision tree that highlights the following key considerations for the use of pesticides in potato crops: Target the use of insecticides and fungicides to meet actual pest and disease risk When selecting pesticides take full account of potential impact on vulnerable watercourses and species in vicinity of the crop. Manage rotations and variety choice to reduce reliance upon nematicides. Monitor slug populations and apply treatments, particularly metaldehyde based products, in accordance with Pelletwise guidelines. Maximise the use of Tied Ridges on sloping fields to maximise water capture and infiltration. On suitable soils use a depressional roller to prevent capping and improve water infiltration. Maintain all irrigation equipment to minimise leakages As part of the field risk assessment ensure there are uncropped areas/grass buffer strips at the base of slopes to slow and catch water, should any run-off occur. Manage water extraction to maximise benefit and minimise the impact on biodiversity and habitats. Buffer in-field ponds and watercourses (This a points scoring option under Environmental Stewardship and a voluntary measure in CFE). 9

10 Supporting biodiversity in the growing crop Environmental Stewardship has been on offer since 2005 and is designed to encourage farmers and landowners to deliver simple and effective environmental management, extending beyond Single Farm Payment Cross Compliance. Entry Level Stewardship (ELS),Organic Entry Level Stewardship (OELS), the new Uplands Entry Level Stewardship (UELS) and Higher Level Stewardship (HLS) all offer opportunities for potato growers to make further environmental improvements. Potato producers can use Environmental Stewardship to protect soil and water and other environmental features on their farm, including wildlife habitats and archaeological features. Entering or retaining an ELS agreement on farm can deliver a useful source of core income from land that is less productive. It can also help to fulfil the requirements of some legislation and ensure that production protocols are met in a cost effective way. A well-planned agreement that is effectively managed and contains the right options in the right location, can be a great benefit to your farm and biodiversity. The agreement will also serve to reduce water pollution and contribute to the aims of CFE.
