five samples, each of 2 litres, must be taken.\n(2) The sample must be taken from a slurry vessel, and—\n(a) if reasonably practicable, the slurry must be thoroughly mixed before the samples are taken, and\n(b) each sample must be taken from a different location.\n(3) But if a tanker used for spreading is fitted with a suitable valve, the samples may be taken while spreading, and each sample must be taken at intervals during the spreading.\n(4) The samples must be poured into a larger container, stirred thoroughly and a 2 litre sample must be taken from that container and poured into a smaller clean container.\n(5) That sample must then be sent for analysis.\nSolid manures\n2 (1) In relation to solid manures, the samples must be taken from a manure heap.\n(2) At least ten samples of 1kg each must be taken, each from a different location in a heap.\n(3) Each sub-sample must be taken at least 0.5 metres from the surface of the heap.\n(4) If samples are being collected to calculate compliance with the whole farm limit for pigs and poultry, four samples for analysis must be taken in a calendar year (one taken in each quarter) from manure heaps not more than 12 months old.\n(5) The sub-samples must be placed on a clean, dry tray or sheet.\n(6) Any lumps must be broken up and the sub-samples must be thoroughly mixed together.\n(7) A representative sample of at least 2kg must then be sent for analysis.\nSCHEDULE 3\nPermitted crops for the closed period\nRegulations 27 and 29\n1 Nitrogen must not be spread on these crops after 31 October.\n2 An additional 50kg of nitrogen per hectare may be spread every four weeks during the closed period up to the date of harvest.\n3 A maximum of 40kg of nitrogen per hectare may be spread at any one time.\nCrop\nMaximum nitrogen rate

following additional requirements apply to derogated holdings.\nDerogation from the measures governing the limit on application of livestock manure\n2 An occupier of a derogated holding must ensure that in any calendar year for which the derogation has been granted—\nA≥(Ngl÷250)+(Nngl÷170)where—\nA is the area of the derogated holding (hectares), as existing on 1 January for that calendar year,\nNgl is the total amount of nitrogen (kilogrammes) in livestock manure from grazing livestock, whether applied directly by an animal or by spreading, and\nNngl is the total amount of nitrogen (kilogrammes) in livestock manure from non-grazing livestock, whether applied directly by an animal or by spreading.\nPlanning the spreading of phosphate fertiliser\n3 (1) In addition to the production of nitrogen spreading plans under regulation 14 (planning the spreading of nitrogen fertiliser) the occupier must–\n(a) assess the amount of phosphorus in the soil that is likely to be available for uptake by the crop during the growing season (“the soil phosphorus supply”);\n(b) calculate the optimum amount of phosphate fertiliser that should be spread on the crop, taking into account the amount of phosphorus available from the soil phosphorus supply; and\n(c) produce a plan for the spreading of phosphate fertiliser for that growing season.\n(2) The occupier must do this—\n(a) in the case of any crop other than permanent grassland, before spreading any phosphate fertiliser for the first time for the purpose of fertilising a crop planted or intended to be planted; and\n(b) in the case of permanent grassland, each year beginning on 1 January before the spreading of phosphate fertiliser.\n4 In addition to the requirements under paragraph 3 the fertilisation plan must record—\n(a) the soil phosphorus supply and the method used to establish this figure;\n(b) the optimum amount of phosphate fertiliser that should be spread on the crop, taking into account the amount of phosphorus from the soil phosphorus supply;\n(c) the amount of nitrogen likely to be available for uptake by the crop from any organic manure intended to be spread for crop uptake in the growing season during the calendar year in which it is spread;\n(d) the amount of phosphate likely to be supplied to meet the requirement of the crop from any organic manure spread or intended to be spread during the calendar year;\n(e) the amount of manufactured nitrogen fertiliser required (that is, the optimum amount of nitrogen required by the crop less the amount of nitrogen that will be available for crop uptake from any organic manure spread during that calendar year); and\n(f) the amount of manufactured phosphate fertiliser required (that is, the optimum amount of phosphate required by the crop less the amount of phosphate supplied for crop uptake from any organic manure spread for the purpose of fertilising the crop during that calendar year).\nSoil sampling and analysis\n5 (1) At least every four years the occupier must undertake soil sampling and analysis for the supply of phosphorus of at least every five hectares of the agricultural area of the derogated holding under the same cropping regime and soil type.\n(2) An occupier may rely on the results of previous phosphorus soil sampling and analysis of the agricultural area of the derogated holding under the same cropping regime and soil type for the purposes of sub-paragraph (1), provided such sampling and analysis was carried out within four years before the derogation.\n(3) Where phosphorus soil sampling and analysis of the agricultural area of the derogated holding under the same cropping regime and soil type has not been carried out before 2010, such sampling and analysis must be carried out as follows—\n(a) 75% of the agricultural area by 1 March 2011, and\n(b) 100% of the agricultural area by 1 March 2012.\nAdditional information to be recorded during the year\n6 (1) In addition to the information to be recorded under regulation 15 (additional information to be recorded during the year) the occupier must, before spreading organic manure, record—\n(a) the total phosphate content of the organic manure; and\n(b) the amount of phosphate likely to be supplied from the organic manure intended to be spread for the purpose of fertilising the crop in the growing season in which it is spread.\n(2) In addition to the requirements of sub-paragraph (1) the occupier must, before spreading manufactured phosphate fertiliser, record—\n(a) the amount required (that is, the optimum amount of phosphate required by the crop less the amount of phosphate that will be supplied for crop uptake from any organic manure spread); and\n(b) the planned date for spreading (month).\nRisk maps\n7 (1) In addition to the requirements under regulation 18 (risk maps), the risk map must—\n(a) show each field marked with a reference number or number to enable cross reference to fields recorded in fertilisation plans;\n(b) correspond with the agricultural area of the derogated holding; and\n(c) be completed by 1 March 2011 and 1 March 2012 for those calendar years.\n(2) The occupier must update the risk map within one month of any change in circumstances.\nMaintaining the derogated holding as a grassland holding\n8 The occupier must maintain the holding to ensure 80% or more of the agricultural area available for manure application is sown with grass during that calendar year.\nClosed period for ploughing grass on the derogated holding\n9 In relation to any grass ploughed on or after 1 April 2010, no person may—\n(a) plough temporary grassland on sandy soils between 1 July and 31 December;\n(b) plough grass on sandy soils before 16 January where livestock manure has been spread on that grass between 1 September and 31 December in the previous calendar year; and\n(c) plough grass on soils that are not sandy soils before 16 January where livestock manure has been spread on that grass between 15 October in the previous calendar year and 15 January.\nSowing of crops following grass on the derogated holding\n10 In relation to the sowing of crops or grass on any grass ploughed on or after 1 April 2010, the land must be—\n(a) sown with a crop with high nitrogen demand within four weeks beginning on the day after the date of ploughing grass; or\n(b) sown with grass within six weeks beginning on the day after the date of ploughing grass.\nCrop rotation on the derogated holding\n11 Crop rotation must not include leguminous or other plants fixing atmospheric nitrogen except for grass with less than 50% clover and other leguminous plants that are under-sown with grass.\nRecording the size of the derogated holding\n12 (1) An occupier must record the total agricultural area and the area of grass within the derogated holding by 1 March 2011 and 1 March 2012 for those calendar years.\n(2) If the size of the derogated holding or area of grass changes the occupier must update the record within one month beginning on the day after the change.\nRecords relating to storage of manure during the storage period\n13 In addition to the requirements of regulation 36 (records relating to storage of manure during the storage period) the occupier must make a record describing the livestock housing and manure storage systems together with the volume of manure storage in place on the holding by 1 March 2011 and 1 March 2012 for those calendar years.\nRecord of nitrogen and phosphate produced by animals\n14 (1) The occupier must make a record of the expected number and category (in accordance with the categories in Tables 1 and 2 in Schedule 1) of livestock to be kept on the holding during that calendar year.\n(2) Following the record making requirements in sub-paragraph (1), the occupier must then calculate and record the amount of nitrogen and phosphate in manure expected to be produced by the livestock on the holding during that year using Tables 1 and 2 in Schedule 1.\n(3) The records to be made in accordance with sub-paragraphs (1) and (2) must be made before 1 March 2011 and 1 March 2012 for those calendar years.\nLivestock manure intended to be brought on to or sent off the derogated holding\n15 (1) The occupier must—\n(a) make a record of the type and amount of livestock manure that is intended to be brought on to the holding and sent off the holding during that calendar year; and\n(b) calculate and record the amount of nitrogen in the livestock manure recorded under sub–paragraph (1)(a) in accordance with regulation 39(4).\n(2) The records to be made under sub-paragraph (1) must be made by 1 March 2011 and 1 March 2012 for those calendar years.\nRecords of crops sown\n16 In addition to the requirements of regulation 41(records of crops sown) an occupier who intends to spread phosphate fertiliser must, within one week of sowing a crop record—\n(a) the crop sown; and\n(b) the date of sowing.\nRecords of spreading phosphate fertiliser\n17 In addition to the requirements of regulation 42 (records of spreading nitrogen fertiliser), an occupier must record—\n(a) within one week of spreading organic manure—\n(i) the total phosphorus content; and\n(ii) the amount of phosphate that was supplied for uptake by the crop; and\n(b) within one week of spreading manufactured phosphate fertiliser—\n(i) the date of spreading; and\n(ii) the amount of phosphate spread.\nRecording the date of ploughing\n18 In addition to the requirements of regulation 43 (subsequent records) an occupier must record within one week of ploughing, the date of that ploughing.\nFertilisation accounts\n19 (1) An occupier, or any person on behalf of the occupier, must submit fertilisation accounts for the calendar year to the Agency by 30 April of the following year.\n(2) The Agency must publish the manner and form in which the fertilisation account must be made.\n(3) The fertilisation account must record—\n(a) the total agricultural area of the derogated holding;\n(b) the area of the derogated holding covered by–\n(i) winter wheat,\n(ii) spring wheat,\n(iii) winter barley,\n(iv) spring barley,\n(v) winter oilseed
