through a fine-crumbling seedbed ensure that as large a proportion as possible of the shed seeds are brought to germination. A concern with the cereal crops is the unimpeded development of the root weeds and root grasses such as couch grass (*Agropyron repens*) and creeping thistle (*Cirsium arvense*), as well as docks forming a taproot. These must be combated after harvest with considerable expenditure of labour and time. Particularly effective here are fully undercutting cultivators with following tines, which fling the roots and root fragments to the soil surface to dry out. Creeping thistle (*Cirsium arvense*) and dock (*Rumex obstusifolius*) in the stand are greatly weakened by deep digging-out before flowering.
