In the Czech Republic, there are several agri-environment schemes focused on biodiversity and improved soil conditions with added benefits contributing to carbon sequestration introduced by the Common Agricultural Policy (CAP) in 2002. In this study, our aim was to analyse historical data of implemented measures with the highest potential for carbon sequestration, assess their outputs and determine which of the agri-environment measures contributed the most during the programming periods and over the twenty years. Apart from analysing historical data (e.g. number of applications, enrolled area and received payment) and assessing their outputs based on sequestration coefficients published in the literature, we have created an algorithm that predicted carbon sequestration over a twenty-year period to assess the contribution of specific measures beyond the duration of programmes. All the sub-measures monitored contributed to carbon sequestration, with the resulting value determined by the amount of land on which the measure was implemented. The results indicate that, over the period under study, the Conversion from Arable Land to Grassland sub-measure was the highest contributor, reaching values of 555,803–606,330 t C and 1,129,317–1,538,235 t C over twenty years. However, the conversion from arable land to grassland is limited by the land suitable for conversion, so it can be assumed that the Catch Crops sub-measure will make a higher contribution in the future. For the period under study, Catch Crops contributed 359,352–598,920 t C. An increase is also expected for the Flower Strips sub-measure. The study advances knowledge on the contribution of agri-environment measures to carbon sequestration and their modelling, a topic that has not been addressed by many researchers to date and is the first of its kind in Central Europe.

在捷克共和国，有几个农业环境计划侧重于生物多样性和改善土壤条件，并为2002 年共同农业政策 (CAP) 引入的碳固存带来额外好处。在这项研究中，我们的目的是分析历史数据实施碳固存潜力最大的措施，评估其产出并确定哪些农业环境措施在规划期间和过去二十年中贡献最大。除了分析历史数据（例如申请数量、注册面积和收到的付款）并根据文献中发表的固碳系数评估其产出外，我们还创建了一种预测二十年期间碳固存的算法，以评估碳固存的贡献计划期限之外的具体措施。监测的所有子措施都有助于碳封存，其产生的价值由实施该措施的土地面积决定。结果表明，在研究期间，耕地转草地子测量的贡献最大，在二十年间达到了 555,803–606,330 吨 C 和 1,129,317–1,538,235 吨 C。然而，耕地向草地的转变受到适合转变的土地的限制，因此可以假设，农作物子措施在未来将做出更高的贡献。在研究期间，捕获作物贡献了 359,352-598,920 吨碳。预计花条子措施也将增加。该研究增进了有关农业环境措施对碳固存及其建模的贡献的知识，迄今为止，许多研究人员尚未讨论这一主题，这在中欧尚属首次。
