SOIL EROSION Janeen Uy I BS MANAGEMENT ES 10 J Submitted to: Dr. Severino Salmo III March 8‚ 2012 Soil is found on the Earth’s crust and formed through weathering and decay of organisms. It may be considered dirt to a lot of people but it is highly an important tool for our survival. The soil holds the roots of the plants where nutrients are stored. It is important since it enables the soil to store and regulate the flow of water‚ filters the pollutants and improves the soil’s quality

being disturbed by birds or any other animal that might eat the seeds. The control of planting seeds wit the seed drill was greatly improved that it saved seeds and allowed most of the plants to germinate at the same rate. This created increased crops and profits for the farmer. The results of the seed drill were greatly welcomed by most people. The growing population of the country sparked a new need for food and farmers. The trade between Europe’s main land and England were very limited

agricultural development marked by new farming techniques and inventions that led to a massive increase in food production. The Agricultural Revolution brought about experimentation with new crops and new methods of crop rotation. These new farming techniques gave soil time to replenish nutrients leading to stronger crops and better agricultural output. Advancements in irrigation and drainage further increased productivity. It was also during this time that inventions were created that greatly increased

Outline the most serious threats posed to the physical environment and vulnerable populations by soil degradation Soil degradation is the decrease in the quality and quantity of soil caused by agriculture and industrial purposes. Types of soil degradation are water and wind erosion‚ physical degradation and chemical degradation. Some of these are human causes and some are physical causes. Overgrazing‚ deforestation‚ overpopulation‚ fertilizer and pesticide use and conflict are some examples of

Ever wondered why organic foods are more expensive? Why organic foods are kept separately from the other food in a grocery store? Why some produce has special labels? The food all looks the same on the outside. An apple marked organic looks the same as any other apple in the produce section of the store. The difference is not the outward appearance but how the apple was grown and processed. The word organic gives the impression that the food will be safer and more nutritious to eat than food without

Social Ideologies: Modified vs Organic Feeding the world is possible but is not probable due to preventative social ideologies. One ideology is held by the person who shops at a grocery store; they want what they want when they want it and if they don’t want to eat it‚ then they will throw it away. They don’t mind genetically modified foods because they want their apple in the summer and they want it to look pretty and polished. They believe genetically modified foods will help feed the world

over 10‚000 years ago‚ believe it or not. It is thought that agriculture first began during a time when there were shortages of plants and large game that would normally be found in the wild. To make up for these shortages‚ people began to plants crops to supply them with the food that they needed. Some people also theorize that agricultural production was driven by figures of great power‚ who would throw feasts to show their dominance over others. Also‚ as population density grew higher‚ so did

significant amount of soil loss each year in Ontario. Soil erosion may be a slow process that continues relatively unnoticed‚ or it may occur at an alarming rate causing serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential‚ lower surface water quality and damaged drainage networks. Erosion by Water The rate and magnitude of soil erosion by water is controlled by the following factors: Rainfall Intensity and Runoff Both rainfall and runoff
