Evaluation of weed distribution and weed spatial stability for precision farming

Original language description

Weed mapping was carried out on 3 fields in central Bohemia to characterize the spatial structure and temporal stability of weed populations over six years (1999 ? 2004). A rectangular grid 40 x 40 m or 20 x 40 m was established with use of GPS (Global Positioning System) along wheel tracks on trial fields. Number of plants for each species and total weed coverage were investigated on the grid points. To determinate the weed occurrence heterogeneity, the Lloyd?s Patchiness?Index was calculated. Using ofSurfer?software, weed maps were created. For single weed species occurrence, the correlation between years was calculated. Results show large differences among fields and document heterogeneous occurrence of weeds. Cirsium arvense, Galium aparine, Tripleurospermum maritimum and Fumaria officinalis showed mainly irregular distribution whereas Viola arvensis and Stellaria media were distributed more uniformly. G. aparine is characterized by relatively high spatial stability. This patchy w
