Conservation tillage practices can reduce or eliminate the need for tillage, and the integration of perennials and cover crops can also protect soil from erosion and contribute to improving soil quality.

The pollutants are picked up by the water as it runs off over the surface or travels through soils and as groundwater, and carried to rivers and lakes.
