Essays on Soil Erosion

Trees are very important in Buhara sub-county in the Kabale district for reasons like income generation, soil erosion control, biodiversity conservation, wood, and charcoal production among others. Eucalyptus species and Pinus species remain part of the dominant tree species planted in Buhara sub-county. Although these tree spp. are widely planted, the environmental effects of plantations comprised of exotic trees such as Eucalyptus spp. and Pinus spp. have been vigorously debated and reports such as drying up of watercourses, affecting the…...

It is believed that globalisation has legion benefits to the economic system of China. In recent decennaries, China has witnessed rapid economic growing due to economic reforms. Its GDP has increased by more than seven percent per annum. However the fact that globalisation negatively affects the environment can non be ignored. Apparently China is witnessing serous environmental jobs. Not merely do these jobs impair the advancement in the economic development but besides have harmful effects on the peoples ' wellness.…...

Botanical name: Cynodon dactylon Common name: Quick grass or couch grass The inflorescence type of quick grass is digitate. It consists of 4 slender spikes that may grow up to 60mm in length and are arranged on the end of the axis in the form of fingers on a hand causing it to be digitate. The growth habitat of quick grass is almost every soil type especially fertile soil but can be found in your common garden to overgrazed and…...

Generally, eutrophication occurs when the rate of nutrient accumulation is greater than the rate of nutrient removal (Heggie, 2006). Because of unnecessary high nutrient content of the soil, plants experience stunted growth, (as indicated in some of its salient features) fishes die in rapid succession, and a general deterioration of water quality. Nitrogen and phosphorus are generally the nutrients which cause these problems, but in estuaries located in temperate regions nitrogen is effective in maintaining plant growth. An estuary has…...

Rainfall and runoff is a water erosion problem also known as splash erosion. This is the first stage in the erosion process. The impact of rainfall drops on the soil surface can break down soil aggregates as the impact of falling raindrops breaks up the topsoil. This erosion is caused by long lasting and less intense storms. Runoff can occur whenever there is excess water on a slope that can’t be absorbed into the soil or trapped on the surface.…...

Deforestation can cause many societal and environmental problems which can make our lives on earth even more challenging. Some of these challenges include: loss of biodiversity, the destruction of forest- based societies and climatic disruption. According to the 1992 United Nations Earth Summit in Rio Janeiro, biodiversity may be defined as, “the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part. Although tropical…...

Soil is one of the most important natural resources of man. Soils are essential for man for growing crops, fodder and limber. Once the fertile portion of the earth's surface is lost, it is very difficult to replace it. In India, the destruction of the top-soil has already reached an alarming proportion. Land degradation problems have resulted in increasing depletion of the productivity of the basic land stock through nutrient deficiencies. In addition to the direct loss of crop producing…...

Trees occupy an important place in the life of man. The trees provide us flowers, fruits, fodder for animals, wood for fire and furniture and provide cool shadow from scorching sun. They give us so many such good things and yet expect nothing in return. Trees give us fruits for food and flowers for pleasure. They provide us timber (wood) for building our houses and making furniture. They provide us wood for fuel. They supply sleepers for the railway line.…...

Natural resources consisting of soil, water, forest, mineral and biodiversity have been repeatedly ruined all over the world by human beings. "Since 1970, over 600,000 square kilometers (232,000 square miles) of Amazon rainforest have been damaged" (Butler, 2011). The FAO (Food and Agriculture Organization) estimated that "soil erosion carries away a volume of soil equivalent to one metre deep over 200,000 hectares every year in the Philippines." In Asia, where water has actually always been considered a plentiful resource, per…...

During the late 1920s, there was an increased number of farmers who practiced mainly arable farming in the south west plains of the United States. The increase in their number led to too much cultivation in the region thus leading to soil exhaustion. Before the settlement of the farmers in the region, the area was mainly covered by grass that prevented soil erosion. Sooner after the settlement of the farmers in the area, the virgin land which was in most…...

What are the negative impacts of soil erosion? Define overgrazing, overcultivation, and deforestation. Include ideas on what people can do differently to reduce the impact of these three practices on soil erosion. Provide examples of where this happens both locally and regionally. Within the examples list the specific consequences. Soil is naturally removed by the action of water or wind: such 'background' (or 'geological') soil erosion has been occurring for some 450 million years, since the first land plants formed…...

Natural resources are useful materials or substances that exist in the environment like land, water, sun, trees, oil, minerals, etc. Natural resources are generally classified as renewable resources and non-renewable resources. Resource depletion means exhaustion of natural resources in a certain region. When the rate of consumption of these resources exceeds the rate at which they are restored, depletion of resources occurs. The utilization of natural resources has increased considerably due to the rapid growth in population. Improvements and advancements…...

Permeability is measured in term of water flow through the soil in a given time. The soil permeability is a very important factor to study the behavior of soil in its natural condition with respect to water flow. The size of pore space and interconnectivity of the spaces help determine permeability, so shape and arrangement of grains play a role. Often the term hydraulic conductivity is used when discussing groundwater properties. Hydraulic conductivity simply assumes that water is the fluid…...

Philippines’ economic status nowadays depends mainly on the production of crops. As we all know, our country has also the advantage when it comes to technology and especially in businesses. Likely in producing products that’s essential to us Filipinos. From this statement, we could conclude the production of materials by factories. Chemicals and other harmful and toxic liquids being used by these factories would greatly affect the soil. Vehicles and other chemical-producing machines penetrate into the soil and also make…...

Science Investigatory projects Dried Papaya Leaves as Organic Mulch for Tomato Plants Mulching in agricultural provides a safe yet equally profitable method of enriching and fertilizing the soil planted with crops. Most often-used mulches are of organic composition, such as dry leaves and barks. Unlike synthetic fertilizers and herbicides, these organic mulches pose no or little damage to the soil and crops. Usually defined as the use of organic and biodegradable materials to give plants the nutrients they need, organic…...
