Erosion Control Measures
ECM of Urban Land - Mulching
Similar to seeding, mulching is a method of applying plant or non-plant materials to cover bare soil surface. The main goal of mulching is to protect the surface of the soil from the impact of erosive forces. In construction sites, mulch can be placed to minimize wind and water erosion. However, the type of mulching selection depends on the land (i.e., slope). Heavy and large sized mulch would be more appropriate for a steep slope. In steep or gentle slopes, matting can be done to hold the mulch in place and reduce its movement by wind or water.
Aside from protecting the soil from erosion, mulching conserves water and reduces soil temperature fluctuations. If the mulch is plant-based or organic, it also increases the soil tilth. For a table of the advantages and disadvantages of various mulch types, click the button below.
