Abstract/Contents:"The results of visual turf boniturs are subject to different influential factors and depend considerably on the actual disposition of the person concerned with the bonitur. Every bonitur is consequently a collection of dates which is very much influenced subjectively which can hardly be reproduced. Experimental results are presented for objectivation and reproduction of turf boniturs by means of the digital use of pictures. The colour channels blue, green, red and close infra red on differently fertilized plots were dealt with by means of a CCD monochrome camera. The digital dates of the pictures were combined with soft ware [software] and evaluated as to the blanks and colours of the turf. The vitality of the grasses was examined by means of radio meter photos. According to the results the blanks in the fertilized plots were reduced with an increasing duration of the experiment. When the effect of the fertilizer applied diminished towards the end of the experiment, the number of blanks increased. The vitality of the fertilized grasses increased parallel to these results with the duration of the experiment, but decreased slightly towards the end of the experiment. It is thus possible, with the assistance of both procedures, to objectively find out location, extent of blanks and vitality. The procedures must still be adjusted in further experiments. It is possible to compare the colour of the turf with RAL colour standards, but this did not produce reliable results in this experiment."
