• Oil Pollution.
• Radioactive Substances.
• River dumping.
• Marine Dumping.

How can we prevent fertilizer pollution?

8 ways to reduce personal nutrient pollution

1. 1) Be Floridian – Fertilize responsibly.
2. 2) Pick up pet waste and reduce poo-lution (even in your own backyard).
3. 3) Keep leaves and grass clippings on the lawn – don’t blow them into the street or down the drain.
4. 4) Direct downspouts into plant beds (rather than down the driveway).

How can we reduce agricultural pollution?

There are several ways to prevent accidents caused by pollution on the farm, especially regarding nutrient runoff….5 Ways to Minimize Agricultural Pollution on Your Farm

1. Add Conservation Buffers to Catch Runoff.
2. Implement Nutrient Management Techniques.
3. Control Livestock Access to Waterways.
4. Minimize Tillage.

How can we reduce fertilizer use?

They also suggest using a slow-release fertilizer that releases nutrients more slowly into the soil, preventing excess nutrients in your grass and thus in the bay. They encourage using compost as a soil conditioner and leaving grass clippings on the lawn, which will act as a natural nitrogen-rich fertilizer.

How can water pollution be controlled?

Self-cleanliness must be kept up and drinking water should not be polluted. Drinking water must be kept covered in a neat place. We should not put our hands into the drinking water holders. Treatment of drainage water is also very important to control water pollution.

How can we prevent agricultural water pollution?

Applying fertilizers in the proper amount, at the right time of year and with the right method can significantly reduce how much fertilizer reaches water bodies. Keeping animals and their waste out of streams keeps nitrogen and phosphorus out of the water and protects stream banks.

What are the factors affecting water pollution?

Many factors affect water quality

• Sedimentation.
• Runoff.
• Erosion.
• Dissolved oxygen.
• pH.
• Temperature.
• Decayed organic materials.
• Pesticides.

What are two sources of pollution?

mobile sources – such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces. natural sources – such as wind-blown dust, wildfires, and volcanoes.

What are the three main types of water pollution?

Water Pollution Sources and Impacts Using this framework, the three main categories of water pollution are point-source, nonpoint-source and trans-boundary.

What is the main goal of sustainable agriculture?

In sustainable agriculture, the goal is to reduce the input of external energy and to substitute non-renewable energy sources with renewable sources (e.g., solar and wind power, biofuels from agricultural waste, or, where economically feasible, animal or human labor).

What is fertilizer pollution?

Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae. Excessive amounts of nutrients can lead to more serious problems such as low levels of oxygen dissolved in the water.
