3 WHO: is responsible to managing Agricultural wastewater? Who: Any farmer with a livestock or poultry operations can be a source of wastewater. WHAT: is Agricultural wastewater? What: Agricultural wastewater is any water that has been affected in quality by human influence which is used for irrigation as a common practice. WHERE: is Agricultural wastewater found? Where: Agriculture is a highly intensified industry in many parts of the world. In rural and pre-urban areas of most developing countries (Asia, Latin America, India and Africa), the use of sewage and wastewater for irrigation is a common practice. HOW: is Agricultural wastewater being used? How: Farmers use water from rivers polluted with sewage or runoff from livestock farms, industry and other contaminated sources to irrigate their cropland. WHY: is Agricultural wastewater being used? Why: Wastewater farming solves several problems faced by these farming communities, primarily an inability to treat dirty water, prohibitively expensive chemical fertilizers and drought conditions.

4 ------------------------------------------------- Non point source pollution from farms is caused by surface runoff from fields during rain storms. Agricultural runoff is a major source of pollution, in some cases the only source, in many drainage basins.

5 Excess of sediments causes high levels of particles in water, which can inhibit growth of aquatic plants, clog fish gills and smother animal larvae. Farmer usually use erosion controls to reduce runoff and retain soil on their fields common, techniques include…

6 Farming practice of ploughing across a slope following its elevation.

7 Is a protective cover placed over the soil, primarily to modify the effects of the local climate. A wide variety of natural and synthetic materials are used.

8 Is the practice of growing a series of dissimilar types of crop in the same area in sequential seasons for various benefits.

9 Nitrogen and phosphorus are key pollutants found in runoff and are applied to farmland in several ways, such as:

10 Applied to promote plant growth; the main nutrients present in fertilizer are nitrogen, phosphorus, and potassium.

11 Organic matter used as organic fertilizers in agriculture.

12 Wastewater developed from industries or municipal buildings.

13 Used to control plant pest and enhance production.

14 The fact is, in many poverty-stricken parts of the world, without wastewater irrigation hunger would be a much bigger problem than it already is. Wastewater farming solves several problems faced by these farming communities

15 While bacteria are a serious health threat, the biggest health issue associated with wastewater irrigation is intestinal parasites. In severe cases, these parasites can end up killing their host. Eat local. It could end up saving you a lot more than money.

16 If there's time, though, the water might be treated using simple indigenous methods. In some areas of Vietnam, Indonesia and Nepal, for instance, farmers create ponds of wastewater and let it sit until some of the pollutants (mostly feces and worm eggs) sink to the bottom, and then they apply the water to the crops. Another cheap water-treatment method involves running it through composting sites. The heat from composting kills a lot of bacteria
