If the levels of these radiations exceed a given limit, they lead to disastrous effects. Various factors are considered to be responsible for soil pollution. The effects of soil-agricultural pollution are harmful and are associated with the sources causing pollution, as enumerated below. The problem arises when their unnecessary pile is dumped on the fields and this organic debris starts to decay by rain water. Planting more tree cover is the best way of reducing soil pollution by minimizing erosion and the effects of floods. Mining and forestry activities that clear the land surfaces (clearcutting) and use ‘skid trails’ often leave the land unrestored. Substances derived from the kitchen include vegetables, peels of fruits-pulses, rotten fruit, vegetable stalks, fruit kernels, tea leaves, egg shells, and leftover after eating. According to scientists, soil pollution is identified as the damages done to the top soil of the land. Soil gets a large amount of human, animal and bird excreta, which constitute a major source of land pollution by biological agents. Founded Conserve Energy Future with the sole motto of providing helpful information related to our rapidly depleting environment. Most potentially harmful substances, however, end up in soils as a result of human activities. Before treatment, the soil is excavated and treated before standard agricultural techniques are applied. In the past, laws to protect the environment weren’t as stringent as they are now. All of these radionuclides emit gamma radiations, which are also harmful to the soil. Others are non-biodegradable, which means they can persist in the soil for a long period. Every cause is linked with another. When combined with atmospheric water, these gases form acids and pollute the soil in the form of acid rain. mode: 'thumbnails-rr', Diseases in humans such as dysentery, diarrhoea, plague, malaria and many other diseases are the result of indiscriminate dumping of waste. Use of inorganic chemical fertilizers is also increasing day by day. The disposal of industrial solid wastes is the major source of soil pollution … (And 5 Ways to Dispose of), Is Junk Mail Recyclable? Soil pollution refers to an undesirable decrease in the quality of soil, either by man-induced sources or natural sources or by both. If the capacity of the soil to mitigate the effects of contaminants is exceeded, the soil turns into a time bomb that can pollute other compartments of the environment. Prevention and control of soil pollution are as vital as water and air pollution control. Natural processes that result in an input of pollutants can be the weathering of ore bodies (inorganic pollutants), volcanic activity or forest fires (inorganic and organic pollutants). Origin and sources of soil pollution The origin of contaminants in the ecosystems may be natural or anthropogenic. Deserts, infertile large agricultural lands, hilly areas devoid of vegetation are the result of soil erosion. The sewage sludge is usually treated before being disposed of into land or water bodies. Also, to prevent plants and animals from getting infected from various germs chemicals such Mailathian, Gamaxin, Dithane M-45, Dithane Z-78 and 2,4-D, etc are sprinkled which are extremely harmful substances. Dry waste includes dust as a result of cleaning, waste paper, cardboard, wooden leaves, broken pots of glass or porcelain, vials, tin containers, hearth-ash, pieces of clothing etc. Sewer sludge may also contain high levels of metals, further polluting the soil. Following are some natural processes that cause soil pollution: Among the available land on the earth, only approximately 50 percent of the land surface is suitable for the use by humans and the animals and the remaining 50 percent of it comprises mountains, trenches, swamps, desert and plateau etc. TYPES, EFFECTS AND SOURCES OF SOIL POLLUTION Soil pollution mainly occurs due to the following: 1. The microbes are collected, cultured, and used to treat the environment. Fertilizers are mostly used to correct the deficiency of soil nutrients. Soil erosion is a very slow process in nature, but its results are far-reaching and widespread. are being widely used. Similarly, organic fertilizers should be used in place of synthesized chemical fertilizers. The pollution of the soil is either caused by natural activities or human actions that destroy its properties, such as structure, composition, and soil biota. Carbon dioxide, nitrogen dioxide, sulfur dioxide, and carbon monoxide are some of the gases produced from industrial activities that cause considerable pollution to soil indirectly. Recycling paper, plastics and other materials reduces the volume of refuse in landfills, another common cause of soil pollution. Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotics (human-made) chemicals or other alteration in the natural soil environment. Bio-fertilizers and manures reduce the need for chemical fertilizer. Human-caused soil pollution can work with natural processes to increase the level of pollution in the soil. Due to the irrigation of fields or vegetable gardens with this water, there is great harm to fruits, vegetables, and various types of food and pulses.

This process is experimental and the keywords may be updated as the learning algorithm improves. The exposed soil is easily eroded and exposed to artificial chemical pollutants from the air, wind, and rain. Naturally, the soil contains contaminants such as metals, salts, inorganic ions, and organic compounds that are mainly formed through soil microbial activity. Carbon dioxide, nitrogen dioxide, sulfur dioxide, and carbon monoxide are some of the gases produced from industrial activities that cause considerable pollutionto soil indirectly. Even if they’re thrown away, they will break down naturally and not cause any toxic chemicals to go into the soil. De-forestation, the cutting down of … In this method, the soil is brought into contact with the right chemical through a chemical process of restoring the natural chemical balance in the soil. These substances include artificial chemical pesticides, herbicides, fungicides, and fertilizers, as discussed below: The introduction of modern pesticides, herbicides, and insecticides has resulted in an increase in the use of agricultural chemicals. The main waste there consists of industrial waste. India alone is using 100,000 tonnes of bio-chemicals per annum and thus the soil is getting increasingly polluted. Biological agents such as bacteria, fungus, viruses, and protozoa are a major source of soil pollution and these are mostly spread through the discharge of human and animal waste which is a major source of soil pollution. Industries are by far the worst polluters of the soil with all the chemicals they release into the environment be it in liquid or solid form. As a result of such kind of pollution in the soil, the growth of crops and plants decreases. Any unwanted change in physical, chemical or biological properties of the soil, which impacts humans and other organisms or the soil’s natural quality such as fertility and utility, is called soil pollution. google_ad_height = 250; Try to use biodegradable products as much as possible. Most of these wastes contain residues of toxic inorganic and organic chemicals, which are extremely harmful. Soil near road.
