comparing and contrasting differences- contour plowing prevents the topsoil from rolling down hills when it rains when conservation plowing takes place the dead crops get left behind to help hold the soil in place. Contour Bunding : Agriculture Engineering Technique For mechanical measures of erosion control. Other advantages include reduced fuel and labor requirements. Some farmers may not have been fully aware of erosion damage and prevention. When is contour plowing used? Other disadvantages to this method can include soil that is too densely packed and lower crop yields over time. Since then, contour plowing and other forms of conservation tillage have been reinstituted. In contour plowing, the ruts made by the plow run perpendicular rather than parallel to the slopes, generally resulting in furrows that curve around the land and are level. However, increased reliance may be placed on herbicides with some conservation tillage systems. 2. However, agriculture practices changed in the 1940s and 1950s when high fossil J.T. Bund Grade: Since the contour bunds are laid along the contours, they are level bunds. Crops are planted between the contour barriers. Benefits of Contour Plowing First, contour farming maintains soil fertility by preventing downwash of the fertile topsoil of a farm and consequently enabling betters yields. What types of strategies does IPM use, and what are its advantages and disadvantages compared to pesticide reliance? No-Till Farming Explain no-till farming. Contour Plowing: plowing and harvesting parallel to the topographic contours of the land No-till Agriculture: leaving crop residue in fields between growing seasons Genetically Modified: a gene with a desirable trait from one organism is inserted into another organism The purpose of contour farming is to reduce runoff and soil erosion on mild slopes. Contour barriers can include piled crop wastes, grassy strips, and hedges. Why is free-range meat (chicken, beef, etc) generally considered better for the environment than CAFO meat? Contour strip cropping (fig. [1] ‘In contour plowing, the plowman plows perpendicular not parallel to slopes.’ ‘A disadvantage is that contour ploughing is unsuited to heavy soils (with high clay content and low infiltration rates), in districts subject to intense rain.’ Soil conservation includes all those measures which help in protecting the soil from erosion and exhaustion. Section 2 Crops and Soil 387 Figure 10 Terracing (left) keeps soil in multiple, small, level fields. Contour farming captures twice the soil moisture and reduces soil erosion up to eight-fold The simple act of planting across the slope instead of up and down the hill does two very important things: it captures at least twice the rainwater and reduces soil erosion up to eight-fold. Contour Plowing Describe contour plowing. The … Plowing should also follow the contour. Grassed waterways are a good solution to the erosion caused by Grassed waterways are a good solution to the erosion caused by concentrated water flows when the watershed area generating the runoff water is relatively large. Increased soil retention encourages root development in crops, and increased water filtration promotes better water quality. Advantages: Less erosion and less fuel and labor required. Practice of plowing or planting across a slope following its elevation contour lines. 3. Contour ploughing mitigates the impacts of floods, storms and landslides on the crops by reducing soil erosion up to 50 percent, controlling runoff water, increasing moisture infiltration and retention and thus enhancing soil quality Producers must consider the advantage and disadvantages of a tillage system before changing systems. Benefits- Lessens resiliency, less harmful chemicals in the ground The limitations of the traditional system of soil conservation , with its "safe disposal" approach to farm water , was an important motivation to develop Keyline design. 1.There is a dramatic reduction in establishment costs through a reduction in the amount of machinery required but also in fuel consumption per acre. How do contour plowing and no-till farming help make agriculture more sustainable? Even with contour … Crop rotation is a low-input form of sustainable agriculture that has been practiced for a long time, dating back to first century B.C. Contour bunding or contour farming or Contour ploughing is the farming practice of plowing and/or planting across a slope following its elevation contour lines. Contour plowingis the practice of plowing along the curves, or contours, of a slope. Farmers no longer have to pay for the labor and the fuel that would otherwise be required for plowing. Random contour plowing also becomes off contour but usually with the opposite effect on runoff, namely causing it to quickly run off ridges and concentrate in valleys. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy precipitation, allowing more time for the water to settle into the soil. Disadvantages:High soil moisture loss, destroys soil structure, compacts wet soil Note: We sell over 100 add Contour plowing prevents erosion, and no- till farming reduces topsoil erosion What types of strategies does IPM use, and what are its advantages and disadvantages compared to pesticide reliance? Contour plowing helps channel rainwater so that it does not run straight downhill, carrying away soil with it. They’re rough on roads and too loud for regular use. Now, you’ve got to put some teeth on that plow. Contour stripcropping is crop rotation and contouring combined in equal-width strips of corn or soybeans planted on the contour and alternated with strips of oats, grasses, or legumes. Once a break-over occurs it is likely to progress all the way down a slope Drawbacks to contour plowing have caused it to be less widely used than conventional tillage methods. Contour Farming Contour farming is farming with row patterns that run nearly level around the hill -- not up and down the hill. The pros & cons of INTERCROPPING June 2018 Before jumping feet first into yet another ‘new’ agricultural practise like intercropping, it is wise to first carefully consider the intricacies of the process – with all the . The disadvantages of contouring are point rows and break-overs caused by reduced water storage capabilities behind the contour ridges as the slope increases. The most important advantage of conservation tillage systems is significantly less soil erosion due to wind and water. Waterways also provide outlet channels for constructed terrace systems, contour cropping layouts and diversion channels. Since you’ll be doing a lot of work in residential areas, steel and carbide edges are out of the question. This method is also known for preventing tillage erosion. It feels like it has been quite some time since I had a long list of things to be done, but suddenly March is upon us and we are thrown into a state of frenzy that any grower would be all too familiar with.
