When fertilizers are washed into rivers, they can cause nutrient pollution, primarily from nitrogen and phosphorus. This leads to algal blooms, which deplete oxygen levels in the water and can create dead zones where aquatic life cannot survive. The resulting ecosystem imbalance can harm fish populations and other aquatic organisms, disrupt food webs, and degrade water quality, impacting both wildlife and human health. Additionally, harmful algal blooms can produce toxins that pose risks to drinking water sources and recreational activities.

What effect do golf courses have on rivers?
Golf courses can impact rivers through runoff of fertilizers and pesticides, causing water pollution. Agricultural practices like irrigation can also lead to water depletion and alter the flow of rivers, affecting ecosystems and wildlife downstream. Proper management strategies, such as using environmentally-friendly products and efficient water use, can help mitigate these negative effects.
What effect do fertilizer have on rivers?
Fertilizers, when washed into rivers through runoff, can lead to nutrient pollution, primarily from nitrogen and phosphorus. This excess nutrient load stimulates algal blooms, which can deplete oxygen levels in the water, creating dead zones that harm aquatic life. Additionally, harmful algal blooms can produce toxins that affect water quality and pose risks to human health. Overall, the impact of fertilizers on rivers disrupts ecosystems and diminishes biodiversity.
How does soil erosion effect rivers and lakes?
In soil erosion the top soil is being removed or washed away by the higher surface runoff.
How is silting of rivers and dams an effect of deforestation?
Removing the forest vegetation increases soil erosion. That soil is washed out into waterways when it rains, increasing the particulate matter in waterways.
Water pollution can be cause by pesticides and BLANK used on farms?
Fertilizers. Farmers put fertilizers on their crops and then the fertilizer can get washed into the ground or into a nearby river therefore polluting it.
What is one problem related to runoff of fertilizers?
Eutrophication
How do nitrates get into H2O?
Fertilizers used in agriculture are partially drained in lakes an rivers.
How did southern and northern Mesopotamia differ in terms of soil fertility?
The headwaters of the Tigris and Euphrates Rivers were in mountainous territory. The rivers washed silt down the rivers and fertile land acumulated in the river basins, replenished each year by the soul washed down the rivers by the rains in the northern mountains.
Grains of sand are washed into rivers and oceans through the process of?
Erosion
What are the limitations of fertilization?
Well inorganic fertilizers are known to work faster than organic fertilizers but they have their disadvantages... (1) Because they are soluble they can be easily dissolved in water and washed away. These fertilizers are known to run off into streams and rivers and cause problems to the wildlife there. (2) Inorganic fertilizers kill the microorganisms in the soil. The organisms are responsible for the breakdown of organic matter and the subsequent release of nutrients into the soil. When these organisms are killed off the soil becomes less fertile. (3) It is claimed that the chemical fertilizers when absorbed not only assist in growth but also contaminates the plants. This contamination is then passed on to us when we consume these plants.
Do synthetic fertilizers harm soil?
Synthetic fertilizers when washed away leave salts and other trace minerals behind. Some of these minerals bond to plant roots eventually clogging them up.
Some farmers use too much chemical fertiliners to replenish soil fertility what is the effect?
Basically, a costly waste of money. The excessive fertilizers are likely to be washed off the soil by rain, and pollute nearby watercourses, streams and rivers. This pollution can rob the water of oxygen, distress or kill off fish and other water depended creatures, and increase chocking weed and algae growth.
