16 Oct effects of soil erosion on agriculture
Sheet Erosion by water is almost invisible. Boosting areas that are prone to erosion with sturdy plant life can be a great way to stave off future effects. Some of the principal causes of soil erosion include: During heavy rains, soil erosion is common. Apart from homework, you have other important things to do in life. So, do not be anxious about asking for assistance with your homework. Consequently, sediment yield-based estimates of the magnitude of anthropogenic acceleration of upland erosion remain questionable.

This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Most commentators, however, generally attribute such erosional episodes to the effects of deforestation (9–12) and neglect the role of agriculture in maintaining accelerated erosion in upland environments. No matter the complexity of your paper, there is a professional writer willing to help. Would you not attend to these first before writing your essay? Knolls and hilltops are usually exposed without any vegetation cover and suffer the most. The paper assesses the cost of land or soil degradation in the Agricultural Sector and its effect on the economy of Ghana with focus on the on-site effects of soil erosion on agricultural productivity. Sometimes too much compaction with sand can lead to an effective crust that seals in the surface layer, making it even harder for water to pass through to deeper layers. Rill Erosion happens with heavy rains and usually creates small rills over hillsides making farming difficult. The erosion processes have been initiated and accelerated by deforestation, overgrazing, and clearing of land for agricultural purposes. Soil erosion can negatively impact agriculture by reducing crop yields and quality. In some ways, this can help erosion because of the densely packed soil, but if it perpetuates greater levels of runoff from rainwater or flooding, it can negatively impact the crucial topsoil. In the mid-20th century, recognition that conventional agriculture dramatically accelerated soil erosion led to experimentation with conservation tillage and no-till agriculture (40, 41). We cover over 100+ disciplines; frequently requested being: Essays, Research papers, term papers, thesis/dissertations, reports, projects, among others. SLM should thus be implemented particularly in the northern part of the country. It is estimated that as much as 80% of the world’s agricultural land is suffering from what is considered moderate or severe levels of erosion. When farming activities are carried out, the topsoil is exposed and is often blown away by wind or washed away by rain. (accessed October 15, 2020). Forms of Water Erosion 3. Data include studies that reported both rates individually and those that simply reported a ratio between erosion rates under native vegetation and conventional cultivation. Switching to organic farming methods is being encouraged in the agricultural sector not only to reduce soil erosion and product crop yields but also for the other numerous environmental and health benefits it brings. Today, there are many parts of the world where farmers cannot practice effective farming because soil has been degraded by soil erosion. By continuing to browse this site you agree to our use of cookies. The best option for enhancing sunflower productivity and quality in semi-arid, high-altitude environments is the application of organic fertilizers amended with reduced amounts of chemical fertilizers. The author declares no conflict of interest. In the same context, Soil degradation may bring about loss of biodiversity. Data has revealed a relationship between reduced crop yields and soil erosion. Soil erosion effects on soil productivity: A By the National Soil Erosion-Soil Productivity Research Planning Committee, Science and Education Administration -Ag ricu I t ural Research CCURATE estimates of future soil A productivity are essential to make agricultural policy decisions and to plan the use of land from the field scale to the national level. This implies that the performance of stone bunds varies by agro-ecological type, suggesting a need for the design and implementation of appropriate site-specific technologies." Sometimes you need guidance in coming up with an outline, selecting the topic, analyzing data, writing a rough draft, carrying out research, among others.

These functions contain the production of food, feed, and fiber ensuring sufficient supplies of clean water, providing a platform for the built environment, supporting biodiversity, and also providing the largest terrestrial store of carbon and nutrients. Tillage Erosion 7. Changes in land use are widely recognized as capable of greatly accelerating soil erosion (14–16), and it has long been recognized that erosion in excess of soil production would eventually result in decreased agricultural potential (2, 3, 17–19). The completed paper is checked by our editors and then emailed or uploaded to your account. When land is worked through crops or other agricultural processes, it reduces the overall structure of the soil, in addition to reducing the levels of organic matter, making it more susceptible to the effects of rain and water. The erosion processes have been initiated and accelerated by deforestation, overgrazing, and clearing of land for agricultural purposes. (And Safe Ways to Dispose Coffee Pods), Effect of Pollution on Plants (And Do They Help Fight Pollution? Other factors as deforestation, improper cultivation practices like mono-cropping, misuse or excessive use of fertilizers, excessive irrigation, over-grazing, the fragility of soil, and poor manuring can accelerate the process of Soil degradation. The world’s agricultural land (About 40%) is severely diminished in quality because of soil erosion and the use of chemical fertilizers, which prevent the land from regenerating. In comparison to soil samples studied from traditionally farmed land, organic land has increased levels of the soil enzymes dehydrogenase, phosphatase, and urease, as well as a significantly higher microbial biomass and a higher polysaccharide content. To restore the lost soil mineral matter and organic content, it would need what is known as land reclamation. The results show the Northern region as the most prone to soil degradation, and that the real cost of agricultural soil degradation as a percentage of real Gross Domestic Product is approximately 2.5% on average, for a 4 year period from 2006 to 2012, which is equivalent to approximately GH¢ 964.92 million in monetary terms. Gully morphology is partly controlled by lithological conditions. Monocropping is the practice of growing the … Characteristics of erosion rate distributions for the compiled data presented in Figs. Your assignment is assigned to a writer based on his/her expertise and experience. This is important, because conventional regression and SDA estimates are obtained without ensuring that there actually exist comparable conserved and nonconserved plots on the distribution of covariates. @2020 BestEssayServices.com.
