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. 2. 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. The most important advantage of conservation tillage systems is significantly less soil erosion due to wind and water. The purpose of contour farming is to reduce runoff and soil erosion on mild slopes. When is contour plowing used? However, increased reliance may be placed on herbicides with some conservation tillage systems. 3. Drawbacks to contour plowing have caused it to be less widely used than conventional tillage methods. 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. 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. The … When done right, this method reduces erosion by more than 50%. Advantages: Disadvantages: Enriching the Soil Discuss compost. Why is free-range meat (chicken, beef, etc) generally considered better for the environment than CAFO meat? Contour farming is the farming apply of plowing throughout a slope following its elevation contour traces. Section 2 Crops and Soil 387 Figure 10 Terracing (left) keeps soil in multiple, small, level fields. 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. Waterways also provide outlet channels for constructed terrace systems, contour cropping layouts and diversion channels. Advantages: Less erosion and less fuel and labor required. 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. 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 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. 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 info@notillagriculture.com. Practice of plowing or planting across a slope following its elevation contour lines. 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. 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. Producers must consider the advantage and disadvantages of a tillage system before changing systems. So, you’re … Continue reading "Snowplow Cutting Edges Polyurethane Versus Rubber" Benefits- Lessens resiliency, less harmful chemicals in the ground Since you’ll be doing a lot of work in residential areas, steel and carbide edges are out of the question. 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 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. Finding that perfect combination of truck and blade wasn’t easy, but you managed. Farmers no longer have to pay for the labor and the fuel that would otherwise be required for plowing. Now, you’ve got to put some teeth on that plow. Plowing should also follow the contour. Soil conservation includes all those measures which help in protecting the soil from erosion and exhaustion. 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 Contour plowing helps channel rainwater so that it does not run straight downhill, carrying away soil with it. 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 Access the answers to hundreds of Erosion questions that are explained in a way that's easy for you to understand. How do contour plowing and no-till farming help make agriculture more sustainable? 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. Contour ploughing Once a break-over occurs it is likely to progress all the way down a slope J.T.
