A direct metering system is significant because it precisely mixes herbicides with diluent water directly from the treated source. This characteristic is essential for ensuring accuracy in the application of pesticides. By using a direct metering system, the operator can maintain the appropriate concentration of the chemical solution needed for effective weed control. This method allows for real-time adjustments to the mixture based on the flow rate or concentration of the herbicide, which not only enhances effectiveness but also minimizes waste.

The other options do not accurately represent the key aspect of a direct metering system. For instance, while uniform distribution of granules is important in some application techniques, it is not specific to direct metering systems which focus on liquid mixing. The reliance on manual labor for mixing solutions does not reflect the efficiency and automation possible with direct metering technologies. Lastly, requiring high pressure for operation may apply to certain types of application systems, but it is not a defining feature of direct metering systems, which can function effectively with various pressure settings depending on the design.
