A baling apparatus including a bale forming chamber in which an agricultural bale is formed, wrapped and subsequently released. The baling apparatus also includes a support extending adjacent the bale forming chamber, the support incorporating a plurality of sensors arranged upon the support, wherein the sensors are adapted to measure a surface property of at least one surface of the bale. Since the surface property of an unwrapped bale will differ from the surface property of a wrapped bale, the baling apparatus can detect whether the wrapping material is sufficiently wrapped around the formed bale to release of the bale without the bale falling apart.
