ABSTRACT:
In calibrating agricultural apparatus for administering agricultural chemical to an agricultural land at a required land concentration, the agricultural apparatus is operated under a predetermined condition to dispense a specimen amount of chemical, which is contained in a container of predetermined cross section. A nomogram, relating specimen amounts of chemical to land concentrations taking into account said predetermined condition, is located on the container such that a zero mark of the nomogram corresponds to a bottom of the container. The level of the specimen amount in the container is observed in relation to the nomogram and is related to a corresponding land concentration. Said land concentration is compared to the required land concentration and the agricultural apparatus is adjusted accordingly.
