Effects of Soil pollution
The unwanted changes or variations in the physical, biological or chemical properties of the soil, which have an adverse effect on the organisms or plants is called soil pollution. It greatly harms the natural quality and utility of the soil.
Degradation in the quality of the soil implies the rapid erosion of soil by wind or aquatic actions, deficiency of micro-organisms living in the soil, the decline or increase in moisture in the soil beyond normal limits, excessive ups and downs in the temperature, lack of humus in the soil, and the excessive growth in the amount of pollutants in the soil.
The natural sources of soil pollution include volcanic eruptions, landslides and rainfall, whereas human causes include use industrial waste, urban garbage, excessive mining and reckless use of chemicals and insecticides in agriculture.
Significance of Soil
Soil is the prime and valuable property obtained through nature. It is a major contribution to the life of humans and animals for whom it’s a source of water, energy and food attainment. It is the source of the food for all the people living on Earth, the creatures as well as the vegetation. If the soil is healthy and pollution free, then all the flora, fruits and vegetables produced from its
Due to flood water, over-utilization of chemical fertilizers, pesticides and bacterial killers and excessive use of land due to multi-cropping system, so many distortions occur in the soil that it tends to lose its essential structure and element to maintain its fertility. The side effects of soil pollution include severe depletion of certain types of calcium, methane, nitrogen, sulphur, iron, copper, nitrogen, potassium and phosphorus in the soil; destruction of some useful plants and organisms which give moisture to the soil; toxic grains, vegetables and fruit that pose health problems to humans and alkalinity in the
Not only does pollution destroy plants but it also affects the health of animals and humans. The affects of pollution on living organisms maybe short and long term. As a child growing I had a friend who was form India, and he would visit every few
Pollutants are contaminants that enter and affect the natural environment which can cause negative changes. There are two main types of pollution, air and water, which occur from different sources and have different effects. Air pollution is the main cause of “dirty air” in the United States. Suburban areas suffer from outdoor air pollutants as well as indoor air pollutants. Indoor air pollutants are caused by the burning of coal and wood, which are used for heating. Outdoor air pollutants are caused by chimneys, in which smoke is released into the air, and crop fertilizers, which are generally used in rural areas. The impact air pollution has on humans are large cases of health defects in rural areas: such as cancer, tuberculosis, heart diseases, and low birth weights. J.P Majra, author of “Air Quality In Rural Areas” states that, “This leads various health problems, mainly affecting the respiratory and cardiovascular system...” (Majra, 2). This shows that if the United States alone uses this much fertilizer, in which affects our health, imagine how much the world will be affected. Kirk Smith, professor of environmental health sciences at UC Berkeley’s School of Public Health states that ”nearly 10% of all lost-life years worldwide” has been due to air pollution (COEH
Growing more organic food would result in more qualitative air and water. As far as organic food is grown mostly on small farms and the process excludes almost any use of pesticides or chemical stuff, organic farming does not create a threat of water and grounds contamination. Moreover, organic farms show a tendency to create more sustainable and richer soil layer due to crops rotations and use of organic composts. Crop rotations also reduce the exposure of plants to pests. The organic farming can also produce benefits in terms of slowing soil erosion and creating favorable environment for changing nutrient demands that are placed on the soil due to use of respective methods food production. In such way products grown on organic farms seem to include more valuable substances, like vitamins, iron, and other types of minerals. Thus, while growing organic food is imposing a positive impact on soils and decreases the intensity of pollution, it also results in higher contents of valuable substances in
With the large and growing population, food sources are increasingly more important. In order to increase the crop yield, fertilizers are used. These fertilizers can come in two forms, inorganic and organic. Also, though these fertilizers may help the human race increase food supply, fertilizer, in excess, can damage the natural environment, killing other organisms. Fertilizer is comprised of three major macronutrients and whether it is organic or inorganic, it can have negative effects on the environment.
For farmers, foresters, and plant ecologists, understanding which nutrients are essential, and why, is basic to understanding why certain plants thrive and others fail. Now, where do these nutrients come from? The answer—soil—is simple. But soil itself is astonishingly complex. Grow crops and food for us to live (FREEMAN) Without plants we can not grow and survive it is essential to our lives. Farmers especially have to explore this process to see which will help them yield better crops and is cost effective. Vegetable we consume for energy to live and grow deficiency of it will affect us as well. It is important to know which soil to pick one that gives us plants right away to satisfy food requirements for the rapid growing population or to pick one that will will be free of chemicals and won't harm our body. Plants contain essential elements for our survival from the food we eat to our medicine we

Like stated above, soil degradation is causing land degradation in Nigeria. Some regions have lost their lands to degradations, which affects land cost, investment, and some other economic activities. In other words, the lands in Nigeria are losing their worth because mismanagement and neglects.
Also, when soil in and close production ranges turn out to be unclean due to dumping of excess material, such terrestrial cannot be used for farming processes. Pollution is also caused by iron and steel mills; zinc, lead, and copper smelters; municipal incinerators; oil refineries; cement plants; and nitric and sulphuric acid plants. Soil pollution is mostly due to elements in herbicides (wild plant killers) and pesticides (toxins which kill flies and other invertebrate mice). Litter is unused material put in public places such as streets, parks, picnic areas and near shops. The addition of waste intimidates the wellbeing of individuals in housing areas. Waste decays, heartens domestic rascals and goes urban places into unappealing, unclean and unhealthy areas to live in.( (Michael
Soil formation: Soil provides multiple services essential for the sustainability of other ecosystem services like nutrient cycling and water retention.
Soil is the most important non-renewable resource on any farm. Healthy soil is key to a good
What is pollution? Pollution is a detrimental enemy to all species that walk on earth. It is a product of mankind carbon foot print on the environment. It consists of chemicals or particles in the air that can harm the health of humans, animals, and plants. Pollution occurs when pollutants contaminate the natural surrounding; which brings about changes that affect our normal lifestyles adversely. Pollutants are the key elements of pollution which are generally waste materials of dissimilar forms. Pollution disturbs our ecosystem and the balance in the environment. With innovation and development in our lives pollution has reached its peaks; giving rise to global warming and human illness. When raw materials, water, energy and other resources
Land pollution can lead to not only soil destruction but also affect others in terms of other pollutions, such as water and air pollution, such as acid rain because they are generated form land itself. The problem with land pollution is that people these days have a miss conceptual about the importance, or generally we can say environment itself to human life, animals and plants. They have forgotten about it or they simply just did not bother to care. Environment has been protected by the law since a long time ago. However, the implementation of rules and regulations pertaining about the matter are still a long way to perfection. It is difficult to cover the whole aspects in protecting the environment as it needs the respective cooperation of several individual and societal influences in order to maintain the preservations of environment.
Water pollution increases the plethora of MOSS in water and it also reduces the level of oxygen in it. According to a survey in most of the rivers the amount of oxygen in a litre of water has decreased to 0.1 cubic centimetre only, while the this average in 1940 was around 2.5 cubic centimetre. Different varieties of fish are the most affected creatures due to water pollution. Contaminated water is not suitable for drinking and even for agriculture purposes. Water pollution is also responsible for destroying the beauty of the lakes and rivers. Also contaminated water negatively impacts, or even eliminates the breeding power of the aquatic life. Moreover, aquatic plants get severely affected due to water pollution. It has been observed that Algae starts to erupt faster. Also the animals falls prey to a variety of diseases due to drinking polluted
Pollution is a massive problem that the earth faces. Pollution is the action or process of making land, water, air, etc…, dirty and not safe or suitable to use. Pollution of air, water, and soil are the most complex issues. Various types of gases and toxins that are released by industries
