Erosion control

Water is the main cause of erosion in Finland. Rainfall and soil surface run-off catch soil particles and carry them into waterways. For example different kinds of agricultural toxins such as herbicides and pesticides, phosphorus, heavy metals and organic matter are attached to the eroding particles.

The most detrimental consequence of erosion in Finland is the weakening of water quality. This occurs especially in intensively cultivated areas following the coastline. Land use activities such as soil preparation or draining land by ditching accelerates erosion and makes it easier for solid particles to end up in water bodies. Undisturbed soils are structures that control erosion. Vegetation cover also prevents erosion of soils.
