摘要翻译：
土壤有机碳(SOC)在改善土壤条件和土壤功能方面起着重要作用。在全球范围内，不断增加的土地利用变化导致SOC含量显著下降。提高农业土壤有机碳含量是减缓气候变化的一种策略。畜禽粪便施用在农田中具有富集土壤有机碳的特点，同时又可作为农作物的天然肥料。本文以西班牙加泰罗尼亚地区为例，对地中海地区低SOC的特征进行了模拟研究，以探讨动物粪便作为有机肥料是否能显著提高农田的SOC。我们的结果表明，4×1000战略的政策目标只能部分地通过肥料运输到田里来实现。这意味着拟议的办法需要与其他战略相结合。

英文摘要：
  Soil organic carbon (SOC) plays an important role on improving soil conditions and soil functions. Increasing land use changes have induced an important decline of SOC content at global scale. Increasing SOC in agricultural soils has been proposed as a strategy to mitigate climate change. Animal manure has the characteristic of enriching SOC, when applied to crop fields, while, in parallel, it could constitute a natural fertilizer for the crops. In this paper, a simulation is performed using the area of Catalonia, Spain as a case study for the characteristic low SOC in the Mediterranean, to examine whether animal manure can improve substantially the SOC of agricultural fields, when applied as organic fertilizers. Our results show that the policy goals of the 4x1000 strategy can be achieved only partially by using manure transported to the fields. This implies that the proposed approach needs to be combined with other strategies.
