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. [1] Producers must consider the advantage and disadvantages of a tillage system before changing systems. Section 2 Crops and Soil 387 Figure 10 Terracing (left) keeps soil in multiple, small, level fields. Drawbacks to contour plowing have caused it to be less widely used than conventional tillage methods. 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. Even with contour … Conservation tillage, contour cultivation, and deep plowing Conservation tillage , such as stubble mulch tillage, minimum tillage, reduced tillage, and no-till, leaves at least 30% of the soil surface covered by plant residue after planting to reduce erosion and surface runoff. Vadas, in Encyclopedia of Soils in the Environment, 2005Conservation Tillage, Contour Cultivation, and Deep Plowing Conservation tillage, such as stubble mulch tillage, minimum tillage, reduced tillage, and no-tillage, leaves at least 30% of the soil surface covered by plant residue after planting to reduce erosion and surface runoff. The most important advantage of conservation tillage systems is significantly less soil erosion due to wind and water. Contour Bunding : Agriculture Engineering Technique For mechanical measures of erosion control. 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 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 Advantages: Disadvantages: Enriching the Soil Discuss compost. How do contour plowing and no-till farming help make agriculture more sustainable? 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. Since you’ll be doing a lot of work in residential areas, steel and carbide edges are out of the question. 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. Contour plowing helps channel rainwater so that it does not run straight downhill, carrying away soil with it. 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. What types of strategies does IPM use, and what are its advantages and disadvantages compared to pesticide reliance? However, agriculture practices changed in the 1940s and 1950s when high fossil Other disadvantages to this method can include soil that is too densely packed and lower crop yields over time. Practice of plowing or planting across a slope following its elevation contour lines. Since then, contour plowing and other forms of conservation tillage have been reinstituted. Contour ploughing 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 2. they both are No-Till Farming Explain no-till farming. Contour farming is the farming apply of plowing throughout a slope following its elevation contour traces. Once a break-over occurs it is likely to progress all the way down a slope This reduces the flow of water (runoff) across the land surface, thus reducing erosion. 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. ‘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.’ Contour plowingis the practice of plowing along the curves, or contours, of a slope. When done right, this method reduces erosion by more than 50%. Soil conservation includes all those measures which help in protecting the soil from erosion and exhaustion. 3) is the production of the ordinary farm crops in long, relatively narrow strips of variable width on •which dense erosion-control crops alternate with clean-tilled or erosion-permitting crops placed crosswise This method is also known for preventing tillage erosion. So, you’re … Continue reading "Snowplow Cutting Edges Polyurethane Versus Rubber" Get help with your Erosion homework. Why is free-range meat (chicken, beef, etc) generally considered better for the environment than CAFO meat? The disadvantages of contouring are point rows and break-overs caused by reduced water storage capabilities behind the contour ridges as the slope increases. Access the answers to hundreds of Erosion questions that are explained in a way that's easy for you to understand. Some farmers may not have been fully aware of erosion damage and prevention. For information about the advantages and disadvantages of no till farming, or to find out how our products can help improve your no till planting, call (800) 417-8020, or e-mail Waterways also provide outlet channels for constructed terrace systems, contour cropping layouts and diversion channels. The purpose of contour farming is to reduce runoff and soil erosion on mild slopes. . 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. Note: We sell over 100 add Farmers no longer have to pay for the labor and the fuel that would otherwise be required for plowing. Bund Grade: Since the contour bunds are laid along the contours, they are level bunds. Increased soil retention encourages root development in crops, and increased water filtration promotes better water quality. 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. Contour barriers can include piled crop wastes, grassy strips, and hedges. When is contour plowing used? 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. Finding that perfect combination of truck and blade wasn’t easy, but you managed. Strip cropping is a method of farming used when a slope is too steep or too long, or otherwise, when one does not have an alternative method of preventing soil erosion. Terrace farming is the levelling of hills and slopes to … Other advantages include reduced fuel and labor requirements. They’re rough on roads and too loud for regular use. J.T. Advantages: Less erosion and less fuel and labor required. However, increased reliance may be placed on herbicides with some conservation tillage systems. Crops are planted between the contour barriers. 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? 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. 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 Contour Plowing Describe contour plowing. Plowing should also follow the contour. 3. The … 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. 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. Contour strip cropping (fig. Disadvantages:High soil moisture loss, destroys soil structure, compacts wet soil Benefits- Lessens resiliency, less harmful chemicals in the ground Sims, P.A.
