欧洲共同体于1988年在自愿的基础上引入了拨备，在1992年共同农业政策的改革下，这是英国大多数可耕种农场获得面积付款的条件。英国在1994-95年度的预留土地面积约为527 000公顷，而在1996-97年度则下降至253 000公顷。讨论了留地对景观和生物多样性的影响，以农场问卷调查为基础，辅之以对生物多样性的实地研究。大多数农民采用轮作预留，虽然作物产量和经济因素是选择预留土地的最重要因素，但预留和其他耕地面积几乎没有明显差异的迹象。大多数轮作留置是在自然更新下进行的，春季喷洒非选择性除草剂。对于频率低得多的非轮作预留地，有类似的自然更新和播种草皮的区域。其他形式的。
Abstract Set‐aside was introduced in the European Community in 1988 on a voluntary basis and, under the reform of the Common Agricultural Policy in 1992, it was a condition for the receipt of area payments for most arable farms in England. The areas of set‐aside land reached around 527 000 ha in England in 1994–95, falling to 253 000 ha in 1996–97. The implications of set‐aside for landscape and biodiversity are discussed, drawbig on farm questionnaire surveys, supplemented by field studies of biodiversity. The majority of farmers adopted rotational set‐aside, and while crop yield and economic factors were the most important factors in selecting land to set‐aside, there were few signs of substantial differences between set‐aside and other areas of arable land. Most rotational set‐aside was under natural regeneration, sprayed with non‐selective herbicides in the spring. For the much less frequent non‐rotational set‐aside, there were similar areas of natural regeneration and sown grass covers. Other forms o...
