Cheshire East Council are investigating the foul smell which has been lingering in the air all week having received a number of complaints from local residents.
A spokesman for Cheshire East Council said: "We are aware of the issue of a strong odour of manure in the Alderley Edge area, following several complaints, and we are urgently investigating the matter.
"Our staff have visited the area to try and identify the source of the material – which is often different from the spreading location.
"The Environment Agency sets the rules about what can be spread, where, and how much manure per acre. However, the Council has powers to investigate odour nuisance – and is doing so. Such odours are typically short-lived, however, dissipating with time.
"The spreading of manure on our Cheshire farmland is a common agricultural practice which happens a lot at this time of year after the harvesting of crops. It is possible the strength of the smell is due to a large number of farms spreading manure at the same time during the limited fine weather and the spreading time limits set by the Environment Agency."
