The application of fertilisers to crops can be monitored and assessed using stable isotope ratios. However, the application of marine biofertilisers (e.g. fish, macroalgae/seaweed) on crop stable isotope ratios has been rarely studied, despite widespread archaeological and historical evidence for the use of marine resources as a soil amendment.

海洋生物肥料对凯尔特豆碳、氮和硫同位素的影响：对重建过去饮食和耕作方式的影响

可以使用稳定的同位素比率监测和评估对作物的肥料施用。然而，尽管广泛的考古和历史证据表明使用海洋资源作为土壤改良剂，但很少研究海洋生物肥料（例如鱼、大型藻类/海藻）对作物稳定同位素比率的应用。
