The roots of trees helps to find the soil and prevent soil erosion. Rows of trees planted along the edges of farms act as wind breakers and prevent erosion by wind. Chemical fertilisers damage the porous structure of the soil and also kill soil organisms such as earthworms which add loose fertile soil to the fields.
