What is one key benefit of using mulch in ROW maintenance?

Using mulch in right-of-way (ROW) maintenance offers numerous benefits, one of which is its ability to suppress weed growth and retain soil moisture. This is accomplished through the physical barrier that mulch creates, which blocks light from reaching weed seeds and seedlings, thus preventing them from germinating and establishing.

Additionally, mulch aids in moisture retention by reducing evaporation from the soil surface, allowing for better water conservation during dry periods. This is particularly beneficial in maintaining the health of desirable plants in the ROW, as they can rely on the available moisture without competition from weeds. Furthermore, the organic matter in some types of mulch can eventually decompose, adding nutrients to the soil over time, though this is not its primary function.

Overall, mulch serves as an effective tool in managing ROW areas by controlling unwanted vegetation and ensuring the climate and soil conditions are favorable for planted species.
