A feedstock processing apparatus for applying, distributing, and compacting feedstock in defined layer heights may include a chassis with a traction drive and a first and second undercarriage, a frame structure that connects the two undercarriages over a span width of the feedstock processing apparatus, a material feeding device coupled to the frame structure, a material distributing device coupled to the material feeding device and displaceable in certain sections over the span width and configured to apply the feedstock in layers on soil in different, predefinable height positions between the undercarriages, and a compacting device displaceably mounted on the frame structure and/or the material distributing device. The compacting device and the material distributing device can be displaced in a manner dependent on one another respectively along a predefinable movement path. A corresponding method is also disclosed.
