| Description
| - This study is dealing with the impact of weed distribution variability and the arrangement of subsamples on the accuracy of the estimation of the Galium aparine population. Rectangular areas of 400 m2 and 600 m2 were defined within a winter wheat field in 2004 and 2006 respectively and the spatial positions of all G. aparine seedlings in the plots were recorded using a coordinate system. Continual sampling with the use of 1 m x 1 m sampling quadrate was simulated and the semivariograms for parallel and perpendicular direction were calculated. On the above two areas, 289 squares at 3 m x 3 m each were created. In each square, sampling with many spatial alignments of four partial samples was simulated. The estimated values of each sampling method were compared with the mean weed density by Pearson`s correlation coefficient. Geostatistical analysis showed, that the range of spatial dependence varied strongly with the sampling direction. Semivariograms showed stronger spatial continuity along the wheel t
