Soil Erosion on Steep Slopes

Steep slopes present a number of challenges to gardeners. They hold inferior soil, are problematic to mow and tend to experience soil erosion,and the steeper the slope the greater the erosion. This article will detail the complications that arise as a result of soil erosion and describe the methods that could be used to counteract them.

Soil erosion occurs when a raindrop hits soil. Without cover to protect it the raindrop has a strong impact which loosens the soil particles, and washes them down the slope of the land. The likelihood of this occurring is increased when a slope is not planted or built on, thus leaving the soil bare. Erosion causes the removal of the nutrient-rich topsoil first, meaning that only a limited number of plants will ever grow in the soil again, and as a result the quality of the soil is significantly decreased. The symptoms of erosion include uncovered tree roots, small stones or rocks visible on the surface, and the build-up of sediment in low lying areas.

To prevent or lessen the impact of soil erosion it is advised to first survey the slope which you wish to conserve and define your specific problems: to what degree does the slope need to be altered?, do you want to solve the issue either by construction or planting? If you did want to plant the slope, is it in a sunny spot that would keep the plants healthy? These aspects must be considered in order to facilitate a model design.

It is recommended to implement a plan that involves as little earthmoving as possible which will be easier when dealing with a smaller slope; however large or very steep slopes will require the services of professionals such as gardeners Bexley. These professionals willbe able to tell you with a degree of certainty the best way to overcome the complications of your slope.

For larger scale slopes the most common practice is to build retaining walls. These walls reduce the amount of necessary earthwork. If you decide to use a series of retaining walls instead of just one large one, they can be instigated in such a way that terraces of a certain size can be fashioned between each; these can be used as small gardens.

An alternative approach is to plant the slope, but this is only wise when working on a small slope. Plants roots solve semi-serious erosion by holding the soil in place, and offering the soil a level of protection from the rain via their leaves or foliage.
