Revisions to the 2009 England June Survey data
The 2009 June Survey figures were revised on 16 September 2010.
The 2009 figures were revised for two reasons. Firstly, the new methodology for 2010 employed thresholds to exclude holdings with very small amounts of activity, so revised 2009 figures were required to permit like-for-like comparisons. Secondly, the census prompted a register cleaning exercise that removed inactive holdings from the register.
Revisions to the 2009 England December Survey data
The 2009 December Survey figures were revised on 1 March 2011.
The December 2009 figures were revised in line with June 2009 figures for the reasons stated above. From 2010 onwards the December figures only relate to commercial holdings as defined by the EU Farm Structure Survey thresholds.
Changes to the source of December sheep data
"A review of the sources of sheep data as at 1 December was conducted in autumn 2010 to investigate the feasibility of using the Sheep and Goat (SAG) Inventory as the source of sheep data for the February returns to Eurostat and Defra publications of December data. Previously, sheep figures were collected in the annual December Survey of Agriculture at the same time that the SAG Inventory was held in England. This switch of sources would yield internal efficiencies and savings, avoid duplication of effort in data collection and reduce the burden of paperwork on farmers caused by Defra surveys. It would also improve the accuracy of the results, as over 56,000 SAG forms were sent out in England in the 2009 exercise compared with the corresponding December Survey’s sample of 15,000 holdings. The review recommended the SAG Inventory should be the source of English data on sheep at December and therefore questions about sheep were removed from the 2010 December Survey form. Results cover all sheep holdings in England. Data on sheep numbers will continue to be collected through the June Survey (for commercial holdings only)."

2009年英格兰六月调查数据的修订
2009年六月调查数据于2010年9月16日进行了修订。
2009年的数据修订基于两个原因。首先，2010年的新方法采用阈值来排除活动量非常小的持有地，因此需要修订2009年的数据以便进行同类比较。其次，普查促进了注册清理活动，从注册中移除了非活跃持有地。
2009年英格兰十二月调查数据的修订
2009年十二月调查数据于2011年3月1日进行了修订。
2009年12月的修订与2009年6月的数据修订一致，原因如上所述。从2010年起，12月的数据仅与欧盟农场结构调查定义的商业性持有地相关。
十二月家禽数据来源的变更
“对截至12月1日的羊数据来源进行了审查，该审查于2010年秋季进行，以研究使用羊和山羊（SAG）库存作为羊数据源，用于向欧洲统计局和英国环境、食品和农村事务部发布十二月数据的可行性。此前，羊的数量是在英格兰年度十二月农业调查期间收集的，同时英格兰的SAG库存也在进行。这种来源的转换将带来内部效率的提高和成本节约，避免数据收集中的重复劳动，并减少由环境、食品和农村事务部调查引起的农民文书工作负担。这还将提高结果的准确性，因为2009年的活动中发出了超过56,000份SAG表格，而相应的十二月调查的样本为15,000个持有地。审查建议SAG库存应成为英格兰十二月羊数据的来源，因此2010年十二月调查表中的关于羊的问题已被删除。结果涵盖了英格兰所有羊的持有地。羊的数量数据将继续通过六月调查（仅针对商业持有地）进行收集。”
