soil binder

A soil binder is a plant, such as certain grasses, used to prevent soil erosion. These plants form dense root systems or surface growth that holds the soil together. Soil erosion, caused by water, wind, or ice, removes valuable topsoil, leading to the loss of nutrients and organic matter. This not only impacts agriculture but can also damage structures.12

The ability of soil to resist erosion depends on its texture and the landscape. Clay-rich soils and humus are more resistant due to strong cohesive forces. Loam and sandy soils offer moderate resistance. Silty soils are the most susceptible to erosion because they have low permeability and their particle size is neither cohesive nor too large to be easily carried away by water. Steep slopes also increase erosion risk. Soil conservation strategies aim to manage erosion rates, with measures like the soil loss tolerance (T-value) helping to determine acceptable annual soil loss to maintain productivity.2
