Contour cultivation follows the contour … When farmers plow their fields along the curves of a slope; Cutting down erosion from the top soil is an example of Contour Plowing. Soil management on slopes is critical for profitable cropping. It is achieved by furrowing the ground with contour lines between the crops themselves. Contour ploughing is a soil conservation technology that is practiced throughout Grenada to mitigate the negative consequences of natural disasters on soil quality and composition. Crops are planted between the contour barriers. In fact, human beingsthemselves are a part of the natural resources. Contour plowing parallel to the Keyline, both above and below will automatically become "off-contour" but the developing pattern will tend to drift rainwater runoff away from the valley centre and incidentally, prevent erosion. Agricultural productivity increased, and as an added bonus the soils were improved by crop rotation, strip planting, terracing, contour plowing, and the use of improved fertilizers, insecticides, and seeds. This document is highly rated by Class 8 students and has been viewed 7140 times. Forms of Water Erosion 3.

These are the different types of resources based on various factors: Contour plowing can increase crop yields from 10 to 50 percent, partially as a result from greater soil retention. For example, a technique called contour plowing may be used to prevent soil erosion and conserve rainfall. and conserves the soil. The Yeomans technique differs from traditional contour plowing in several important respects. Plowing should also follow the contour. Beginning in the 1930s, the ravages of the boll weevil and federal crop restrictions and conservation programs encouraged many farmers to turn from cotton farming to growing other crops, such as soybeans; to sowing grasses for livestock; and to planting trees for timber. All Rights Reserved. Contour plowing can increase crop yields from 10 to 50 percent, partially as a result from greater soil retention. When did organ music become associated with baseball? What caused the change from figure 1 to figure 2? Contour ploughing and Keyline planning (ploughing) Contour ploughing or contour farming is the farming practice of ploughing and/or planting across a slope following its elevation contour lines. Contour plowing forms ridges, slows the water flow and helps save precious topsoil. Thank you! A soil conservation method called strip-cropping is often combined with contour plowing. Effects of Water Erosion 4. Effects of Wind Erosion 6. Our website takes security and privacy seriously. Figure 1 shows a seaside cliff. By 1938, the introduction of new agricultural techniques such as contour plowing had reduced the loss of soil by 65% despite the continuation of the drought. Gradually, a terrace builds up between permanent contour barriers. Contour plowing helps channel rainwater so that it does not run straight downhill, carrying away soil with it. Contour farming was practiced by the ancient Phoenicians, and is known to be effective for slopes between two and ten percent. ‘Examples might be contour plowing, where the contour needs to be re-established periodically, or delayed haying for nesting birds, which reduces forage value.’ ‘Crop rotation, contour plowing, and the careful use of fertilizers and pest controls increased productivity, but the same techniques made it easier for bigger farms to become even more productive.’ At one end of a contour the slope of the land will always be steeper than at the other. Farming sites are often classified into five levels: insensitive, mild, moderate, high and extreme, depending on the regions soil sensitivity. 1. Conservation tillage, contour cultivation, and deep plowing. Improve the soil … Tillage Erosion 7. This method was actually practiced by the ancient Phoenicians and has been known to retain more soil and increase crop yields from 10 to 50 percent. Contour plowing was practiced by the ancient Phoenicians, and is effective for slopes between two and ten percent. Contour plowing was a method of plowing furrows that follow the curves of the land rather than straight up and down slopes. Dec 22, 2020 - Difference between terrace farming , contour ploughing and contour barriers with explanation? When farmers plow their fields along the curves of a slope; Cutting down erosion from the top soil is an example of Contour Plowing. pro 2- going back and forth save gas cost for the farmer. Plowing. What Are The Different Types Of Sustainable Agricultural Practices? Contour plowing is the act of farming on a hill or a contoured area. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy water run-off; which is a major cause of top soil loss and soil erosion. 20. Copyright © 2020 Multiply Media, LLC. There are many erosion control examples such as conservation tillage, crop rotation, and growing cover crops. Contour plowing is normally used only when the slope of the land is between 2 to 10% and when excessive rainfall is not generally a problem. Contour plowing reduces runoff and helps crops and the soil to maintain a constant altitude. Wind Erosion 5. The water break also allows more time for the water to settle into the soil. 1 shows contours in an area with contour interval of 1 m. On contour lines the level of lines is also written. Water Erosion 2. (a) Renewable (b) Flow (c) Biological (d) Non-renewable ... Contour ploughing (b) Strip cropping (c) Creating shelter belts (d) Ploughing up and down the slopes (d) Ploughing up and down the slopes. The outline of the mountains seen in the distance is an example of the contour of the mountains. Contour plowing or contour farming is the plowing and planting across a slope following its elevation contour lines. Who is the longest reigning WWE Champion of all time? Which of these actions is an example of chemical weathering? Random contour plowing also becomes off contour but usually with the opposite effect on runoff water causing it to quickly shed off ridge shapes and be concentrated in valleys. Plowing fields along the curves of a slope to prevent soil loss. The limitations of the traditional system of soil conservation, with its "safe disposal" approach to farm water was an important motivational factor in the development of the Keyline system. Although traditional plowing methods prevent weed problems and also help prepare the farm for planting, plowing … In many countries including Australia, it is important to get optimum absorption of rainfall and Keyline cultivation does this as well as delaying the potentially damaging concentration of runoff. He made a series of studies and published reports outlining more efficient methods of utilizing water in the semi-arid southern Great Plains region, such as terracing and contour plowing. What are the release dates for The Wonder Pets - 2006 Save the Ladybug? Cutting down erosion from the top soil is an example of Contour Why don't libraries smell like bookstores? Contour plowing can increase crop yields from 10 to 50 percent, partially as a result from greater soil retention. Contour ploughing is a well-established agronomic measure that contributes to soil and water conservation [ 25] (see figure 1). The contour lines in an area are drawn keeping difference in elevation of between two consecutive lines constant.

Fossil fuels are examples of which of the following types of resources? Effects of Tillage Erosion 8. Conversely, contour plowing slows water runoff and as such, prevents soil erosion and allows the water to infiltrate the soil. The practice of rotating use of different fields from crop to crop each year, to avoid exhausting the soil. Contour plowingis the practice of plowing along the curves, or contours, of a slope. The Soil Conservation Service worked with state governments and universities with established agriculture programs such as the University of Nebraska to promote the method to farmers. The Nation's River, by United States Department of the Interior. This lines create a water break which reduces the formation of rills during rains, because lines let more time for the water to settle (stay) into the soil. Strips of grasses, shrubs, or other plants are Keyline pattern cultivation on ridge shapes is done parallel to any suitable contour but only working on the upper side of the contour guide line. Through example, the organization hopes to protect and preserve the watershed for public enjoyment and education. Contextual translation of "contour plowing" into Tagalog. This method equally prevents soil erosion and can improve soil fertility through crop rotation. For example, the contour map in fig.
