Abstract:
... Creeping thistle (Cirsium arvensis (L.) Scop.) is a perennial weed that causes yield loss in sugar beet (Beta vulgaris L.) crops. The weeds are usually mapped for site specific weed management because they tend to grow in patches. Remote sensing techniques have shown promising results in species discrimination and therefore provide potential for weed mapping. In this study we examined the feasibil ...

Abstract:
... Wild blueberry crop yields are dependent on heavy agrochemical applications to control weeds competing with the crop. Goldenrod is a creeping herbaceous perennial weed that occurred in 90% of wild blueberry fields surveyed in Nova Scotia. A colour co-occurrence matrices (CCMs) based algorithm can be used for spot-application of herbicide on goldenrod within wild blueberry fields. The objective of ...

Abstract:
... Silage is one of the typical systems to preserve biomass usually oriented from corn, sorghum, wheat, grass, and other forage and perennial crops. A critical task within the logistics operations in silage production, i.e. harvesting, transporting, and compacting, is the management of the biomass flow, in connection with the biomass storage system and the required conditions of the stored product de ...
