Illustrated guide of determination of organisms on the field, consisting of at least one sheet of card (23), that has printed multiplicity of displays of organisms (14) that are encountered on the field and multiplicity of marking mechanisms (16) arranged adjacent to each one of the displays of organisms (14) and the printing in a column (17) adjacent to each marking mechanism (16) of an indication (20), typical of the stopping of the marking mechanism (16) and at least one more typical indication (21) connected with predefined information related to the displayed organism, e. g. the observed by the user presence of the organism on the field. The marking mechanism (16) includes a stem (28) supplied with an index (19), that is shifted by the user during his visit on the field in order to indicate by the shifting of the index (19) in a matching position with the typical indication (21) the presence of the specific organisms (14) on the field, for which the adjacent arranged marking mechanisms (16) have been shifted in the typical indication (21). |
