The invention refers to an apparatus (1) and a method for forming a plurality of bales from loose material which is picked-up from the ground (BS). The picked-up loose material is conveyed into a processing chamber (Ch). The processed loose material is transferred from the processing chamber (Ch) onto a bale carrier (18, 62). A bale (B) is formed from transferred loose material and is deposited from the bale carrier (18, 62) onto the ground (GS). For every bale (B) of the plurality the inclination or further property of the ground (GS) at one location is measured. The bale (B) is deposited at a location where the bale (B) cannot roll downhill. Loose material is also picked-up while a bale (B) is on the bale carrier (18, 62).
