sprøjtebredde

Sprøjtebredde refers to the effective width covered by a spray application, most commonly used in agriculture when referring to pesticide or fertilizer application. It is a crucial parameter for calculating the amount of product needed and for ensuring uniform coverage of the target area. The sprøjtebredde is determined by the number and spacing of the spray nozzles on the boom of a sprayer. Each nozzle produces a spray pattern, and the overlap between these patterns dictates the overall effective width.

For example, if a sprayer has ten nozzles spaced 0.5 meters apart, and each nozzle effectively covers a width of 0.5 meters, the total potential width might seem to be 5 meters. However, to achieve uniform coverage and avoid gaps or overlaps, the spray patterns are designed to overlap. Therefore, the actual sprøjtebredde might be slightly less than the sum of individual nozzle widths, or it could be calculated based on the distance between the centers of the outer nozzles multiplied by a factor accounting for the overlap.

Accurate knowledge of the sprøjtebredde is essential for proper application rates. If the sprøjtebredde is overestimated, too little product will be applied, leading to ineffective treatment. Conversely, if it is underestimated, too much product will be used, resulting in wasted resources and potential environmental damage. Manufacturers provide specifications for their sprayers and nozzles that indicate the effective sprøjtebredde under typical operating conditions, which can be influenced by factors such as spray pressure and nozzle type. Field calibration is often performed by users to verify the actual sprøjtebredde for their specific setup and conditions.
