Management of contaminated water (industrial and domestic) in agriculture

Environmental pollution is the biggest problem today.  Increasing industrialization has had serious adverse effects on the environment due to changes in our lifestyle.  The effects of uncontrolled, erratic, and haphazard development in the world over the last 150 years are in front of us in the form of water and air.  We need to understand that if toxins are mixed in the water, the water which is life-giving can also become life-giving. Water is a universally soluble form.  Other organic or inorganic solutions do not contain as many soluble elements as water.  Due to this property of water, its use is ubiquitous.  The number of water-borne diseases in the world is innumerable.  Many diseases like water-borne jaundice, diarrhea, diarrhea, digestive diseases cause many deaths in the world.  Thus water pollution caused by industries and human activities causes many diseases.  Water management is a very big and complicated problem.  Here are some suggestions on how to look or get an appointment for acne treatment.

Water is contaminated by chemical fertilizers, pesticides, animal excrement, crop residues, or soil particles mixed with water flowing on the surface of the soil.  The main purpose of farm management is to save contaminated water in agriculture.

Pollution from inaccurate sources:

Rainfall with hurricanes is an inaccurate source.  During this time erosion occurs mainly from the farms.  This type of erosion also occurs in some watershed sheds in some cases.

Erosion  by silt:

Soil erosion from farms is one of the major sources of agricultural pollution.  Excessive siltation in water bodies causes siltation which inhibits the growth of vegetation growing in or near the water, obstructs the feet of fish, and traps small insects.  Farmers should prevent soil erosion due to the flow of rainwater.

Common methods:

• Plowing the top line.
• Let the grass grow between the rows of crops.
• Crop rotation.
• Planting perennial crops.
• Build a grass fence at the end of the field to prevent erosion.

Nutrient depletion:

Contaminants such as nitrogen and phosphorus are mainly found in farmland erosion and are used in farmlands in the form of chemical fertilizers, animal manures, contaminated water, or sludge from towns as well as industries.  These chemicals are also added to erosion from crop residues, irrigation water, wildlife, polluted weather, etc.

Farmers can develop nutrient management schemes to maintain water quality:

• To prepare information and documents of crops, type of land, type of soil, reservoirs, etc.
• Obtain real estimates of crop yields.
• Soil testing and analysis of nutrients in manure.
• Identify sources of significant nutrients (e.g. irrigation water).
• Drain the deep surface of the erosion and evaluate significant sites such as shallow aquifers.
• Use of chemical fertilizers, manure fertilizers, etc. based on precision techniques of agriculture with the aim of getting the prescribed yield.

Pesticides:

Farmers often use pesticides to control pests and increase production but water is contaminated with chemical pesticides.  Pesticides remain in groundwater for the following reasons.

• Direct use of pesticides (e.g. aerial spraying or water body spraying).
• Flowing water when it rains with a hurricane.
• Some of the pesticides are also found in the groundwater by wind blowing sand from nearby farms.
• Farmers use integrated pest management (including biological pest control) techniques to control pests and maintain water quality.  Some are safer than stopping at a landfill site in a systematic way or banning disinfection by incineration.

Pollution from a specific source:

Animal waste:

Livestock and poultry farms, as well as farm farms, maybe the main sources of contaminated water.  A solid or semi-solid liquid slurry is prepared from animal excrement.  The liquid slurry is especially important for farmers who keep milch cattle.
