SUSTAINABLE AGRICULTURE: differences with industrial agriculture

Waste water is any water that has been affected by human use. Wastewater is "used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff or stormwater, and any sewer inflow or sewer infiltration".Therefore, wastewater is a byproduct of domestic, industrial, commercial or agricultural activities. The characteristics of wastewater vary depending on the source. Types of wastewater include: domestic wastewater from households, municipal wastewater from communities (also called sewage) or industrial wastewater from industrial activities. Wastewater can contain physical, chemical and biological pollutants.

Soil is the foundation of most types of agriculture. But soil health is negatively impacted by industrial agriculture practices like monocropping, synthetic fertilizers, pesticides and more. Monocropping is the practice of growing the same crop on the same plot of land, year after year. This practice depletes the soil of nutrients (making the soil less productive over time), reduces organic matter in soil and can cause significant erosion. Industrial farming practices often include the rotation of soybeans and corn. Technically, because two crops are in rotation, this does not get classified as a “monoculture.” However, this “simple” form of crop rotation does not provide the same benefit to the soil as do complex systems (in which three or more crops are rotated over a period of one year or longer). When crops are grown in complex rotation, yields go up by as much as 10 percent in a non-drought year.
