随着罗马人的征服，英国的农业生产面临着大量城市人口和军事人口日益增长的需求。虽然长期以来人们一直认为这需要增加农业生产，但耕作方式变化的直接考古证据很少。本文使用一个模型，从集约化或集约化实践的角度对谷物种植策略进行概念化，是第一篇使用作物遗骸的碳和氮稳定同位素数据来解决这个问题的研究。本文报道了41个来自青铜时代、铁器时代和罗曼·斯坦威克（Northants.，英国），以评估耕地的集约化程度，并调查在史前和罗马英国的耕作实践的转变。结果表明，在罗马时期，δ 15 N下降，这表明农业实践转向了较低的施肥水平，这意味着变得更加广泛。δ 13 C值在所有时期都是可比的，这支持了这样一种观点，即在铁器时代和罗马时期之间观察到的人类稳定同位素数据的变化最好是由饮食变化来解释的，而不是食物链基础植物中δ 13 C值向更高的转变。
ABSTRACT Following the Roman conquest, agricultural production in Britain faced increasing demand from large urban and military populations. While it has long been thought that this necessitated an increase in agricultural production, direct archaeological evidence for changes in cultivation practices has been scarce. Using a model that conceptualises cereal farming strategies in terms of intensive or extensive practices, this paper is the first study to address this question using carbon and nitrogen stable isotope data of crop remains. We report δ15N and δ13C values from 41 samples of spelt, emmer and barley from Bronze Age, Iron Age and Roman Stanwick (Northants., UK), in order to assess the intensiveness of arable farming and investigate shifts in cultivation practices in prehistoric and Roman Britain. The results demonstrate a decline in δ15N in the Roman period, suggesting that farming practices moved to lower levels of manuring and, by implication, became more extensive. δ13C values are comparable in all periods, supporting the suggestion that changes observed in human stable isotope data between the Iron Age and Roman period are best explained by dietary change rather than a shift towards higher δ13C values in plants at the base of the food chain.
