text: how to prevent soil erosion?   - respect for the original plant cover. a native biome is there for a reason and usually represents the best balance between soil, climate and biotic factors. - reforestation in case the original plant cover is removed. this may include planting trees, bushes or herbs, whatever is more adequate; also not removing the natural vegetation of ditches and irrigation channels, which prevents the soil from being carried away by the water. - environmentally-friendly agricultural techniques (less heavy machinery, zero tillage, etc.) - avoid heavy trampling (by machinery, vehicles, cattle, etc), because it causes soil compaction, inhibiting the growth of plant roots and thus exposing the soil to erosive factors. - sustainable agriculture also implies healthy irrigation methods. excessive or badly distributed irrigation may lead to salinization, desertization and increased vulnerability to wind and water erosion. - care for the soil fauna and flora. the geobios (living organisms in the soil) are absolutely essential for normal soil fuctions. interruption of their processes and cycles leads to faster degradation. - hire engineers with common sense and provide thorough environmental impact studies before building roads, bridges, channels, or anything else.   - above all, respecting the limits for production in any given soil and being aware of the timescale necessary for normal soil functioning.
