Metering apparatus, by means of which liquid agricultural chemicals, such as, for example, dressing agents, sprays, etc or the like, are added in a metered manner from supply containers to media located in mixing containers. In order to provide a closed metering apparatus for agricultural chemicals which has a high metering accuracy, provision is made for designing the metering apparatus (16) as a pump (15) which has a suction conduit (17) and a metering conduit (19), for the respective chemical to be sucked off from the supply container (18) via a suction conduit (17) inserted into the supply container (18), and for the metering conduit (19) to open out in the mixing container (2) (Figure 1). <IMAGE>
