Weed mapping ? an important part of the precision farming

Popis výsledku v původním jazyce

Three-year field trials performed during 2005 ? 2007 were focused on the study of weed distribution on selected plots with growing of potatoes. In the period of potato emergence, coordinates were determined for each point in the grid of 20x20 m using ofGPS kit GPSMap 276. and values of distribution of all present weed species (g green mass/m2) were assigned to the coordinates. From obtained values aggregate maps of weed distribution and also of individual weed species were separately constructed. GPS data were primary processed using of MapSource 5.4 software and maps of weeds were constructed using of mapping software Surfer 8.04 (data interpolation was done by kriging). It was found that it is possible to reduce herbicide usage by 40 % on a plot with generally lower weed distribution with this measure. This procedure has the highest effect in application against locally distributed weeds such as Cirsium arvense and Sonchus arvensis.
