【 摘 要 】

The objective of this work was to identify the differences between the seedbank of a sugarcane field harvested mechanically and a that of a burned sugarcane field, using precision agriculture techniques. The soil sampling for seedbank determination were performed using a 2 ha regular sampling grid. The weed infestation maps were obtained by the kriging interpolation technique. The green sugarcane field presented lower weed infestation potential compared to the burnt sugarcane field, specially the monocotyledonous species. However, some dicotyledonous species can be selected, such as the Ipomoea. It was concluded that precision agriculture can be useful tool for determination of weed infestation maps and that sugarcane straw can be used as a suppression factor for various species.
