This paper aims to raise awareness of a significant and developing challenge for archaeological geophysics. The widespread use of fertilizers and soil conditioners derived from so-called ‘green waste’ (biodegradable and organic materials) is becoming commonplace and the diversion of this waste from landfill is widely perceived as having numerous environmental benefits. Unfortunately these environmental benefits on the macro-scale are having a negative impact on the historic environment at the micro-scale. Ferrous contaminants within 'green waste' are having a serious impact on archaeological geophysics using the principles of magnetism. This paper discusses how the spreading of 'green waste' on a field in Somerset masked and obscured archaeological anomalies in a survey carried out using a fluxgate gradiometer. The paper calls for tighter regulation of green waste and research on how its impact on the historic environment can be mitigated.
