However this phenomena (Eutrophication) water becomes cloudy and normally shade green color and this water clarity decreasing reduce the amount of absorbed light for alga. In addition microorganisms and bacteria’s decompose dead alga and other planets and consume remained oxygen in the ponds and lakes. Eutrophication slowly limits various usages of lakes or ponds such as recreation, fishing, and even public health problems in case of influence to drinking water. There are two main type of eutrophication which are natural eutrophication and cultural eutrophication. Naturally nutrients loading during long time cause alga blooming, and natural eutrophication during decades.
Eutrophication is an extreme wealth of supplements in a lake or different waterways. Eutrophication happens when the spillover of residue from and land go into a waterway. At the point when this happens, a thick development of vegetation happens, which exhausts the huge oxygen request (BOD), which means the oxygen that is accessible to amphibian life is no more. Eutrophication might likewise be realized by the seepage of sewage, mechanical squanders, or cleansers into a waterway. As the stuffed plants cease to exist, the dead and rotting vegetation exhausts the lake 's oxygen supply.
This occurs because excess nutrients can fuel the growth of algae blooms that block sunlight from reaching underwater grasses and, during decomposition, rob the water of oxygen that plants and animals need to survive. Certain species of algae that are common in bodies of water plagued by eutrophication can also contaminate shellfish. When consumed by humans, these diseased aquatic invertebrate cause paralytic shellfish poisoning: a potentially fatal disease. Unfortunately, though there are many drawbacks and negative effects on the water quality in the Bay, no real benefits are found in the water when agricultural pollution is present. The most destructive components of agricultural pollution are livestock manure, poultry litter, and chemical fertilizers.
The excess nutrients may induce pathogen and provide the elements required by the pathogen to proliferate or become directly toxic to the coral making them more susceptible to the disease.The imbalance in the exchange of nutrients between the zooxanthellae and the host coral reduces light penetration to the reef due to nutrient-stimulated phytoplankton growth, and, most harmful of all, may bring about proliferation of seaweeds (Dubinsky, 1996).Nevertheless, the study had discovered that the coral capable to recover and revive once the nutrients supplies stopped. Last but not least, various chemicals of pesticides and fertilizers from agriculture practices are flowing into the water cycle via soil infiltration and surface run-off. One of the most critical threats
These processes are usually wet to enable material transport and to reduce dust. Phosphate rock is THEN mixed with sulphuric acid to produce weak phosphoric acid. This phosphoric acid is mixed with various other minerals to produce liquid or solid fertilizers. Theses process vary with respect to the fertilizer being produced. Frequently manufactured fertilizers are triple superphosphates (SSP, TSP) and ammonium phosphates (MAP, DAP).
Eutrophication occurs when there is an over supply of nutrients in an environment, and can cause serious problems especially in water bodies. The increase in nutrient levels could result in algal blooms which is detrimental to the water resource, as algal blooms disrupt the natural ecosystem that functions in the water resource and take in the oxygen in the water body and blocks out sunlight. As little or no oxygen is present in the water resource, much of the aquatic life dies out, resulting in dead zones. Luckily, dead zones mostly occur in smaller water bodies, and since Loktak Lake is a large one, it did not become a dead zone, but still faces the problem of eutrophication. Eutrophication makes water resources unsafe for use as certain algal blooms, fertilizers or pesticides contain harmful chemicals that is not safe for
Fertilizers remove the nutrients of the soil damaging the soil and the local environment and after being mixed with the soil, gradually reduce the fertility of the soil. In the study of (Southland) using fertilizers consists of substances and chemicals like methane, carbon dioxide, ammonia, and nitrogen, the emission of which has contributed to a great extent in the quantity of greenhouse gases present in the environment. These facts are alarming and a serious step needs to be taken as soon as possible to avoid more severe consequences. This in turn is leading to global warming and weather changes. The use of fertilizers for growth and cultivation is keeping our stomach filled for now, but then if things keep on progressing the way they are, it won’t take long to see the times where there is lack of food, water, and health.
Recharge by runoff from irrigation water into groundwater as well as leaching of agrochemicals cause serious groundwater contamination problems. The clearing of natural vegetation and ploughing up of virgin land for new cultivation also affect the groundwater quality. Irrigation is one of the major sources of salinity in the soil through which rainwater flows to the water table. The dissolution of these salts finally
