Contour farming is farming with row patterns that run nearly level around the hill -- not up and down the hill. Requires protected head ditch- es and waste-water ditches. they both are conservation methods for soil sources- "Tillage Erosion." [12] Contour farming is applied in certain European countries such as Belgium, Italy, Greece, Romania, Slovenia and Spain in areas with higher than 10% slope. They’re also praised for their durability. Contour farming, the practice of tilling sloped land along lines of consistent elevation in order to conserve rainwater and to reduce soil losses from surface erosion. 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. Equipment used in planting, cultivating, and harvesting has to be turned on... 4. Contour plowing (or contour ploughing) or contour farming is the farming practice of plowing across a slope following its elevation contour lines. 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. Ploughing leaves very little crop residue on the surface, which otherwise could reduce both wind and water erosion. However, disadvantages of irrigation include increased leakage of water,makes local temperature damp, and has high beginning expenses. Contour plowing is the farming practice of plowing across a slope following its elevation contour lines. Increased moisture levels in the soil may lead to an increased risk of fungal crop diseases [sc:1]. Importantly, the technique also significantly reduces soil erosion, fertilizer loss, and overall makes farming less energy and resource intensive under most circumstances. Contour Farming is done across the slope and is one of the best methods for small scale as well as large scale farmers . It facilitates seeding with a lighter seeder. The extent of the problem was such that the 1934 "Yearbook of Agriculture" noted that Approximately 35 million acres [142,000 km²] of formerly cultivated land have essentially been destroyed for crop production. With no-tillage farming, there may be an increase in weed growth that leads many farmers to increase their application of herbicide on their crops. Dryland Agriculture involves contour Farming. 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. The propagating tunnel is almost totally full up and when the soil begins to dry out again (after more rain since the ploughing) we will get onto sowing peas direct outside and planting modules will begin early next month. 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. Soil erosion caused from heavy rain can encourage the development of rills and gullies which carry excess nutrients into freshwater systems through the process of eutrophication[9]. Go to the National Geographic Web site to find some ocean-friendly substitutes for her seafood choices. The rows form slow water run-off during rainstorms to prevent soil erosion and allow the water time to settle into the soil. 1. It accelerates soil warming and water evaporation in spring because of the lesser quantity of residues on the soil surface. <, "Contour Farming." It is performed by following the natural contours when tilling the soil, planting and cultivating. Typically farmers break up hardpan up with a subsoiler, which acts as a long, sharp knife to slice through the hardened layer of soil deep below the surface. Disadvantages of Intercropping system are: Yield decreases as the crops differ in their competitive abilities; Management of I/c having different cultural practices seems to … Overall, contour … [4] Contour farming is considered an active form of sustainable agriculture. Chisel: Less winter wind erosion from roughened surface. This can lead to large scale desertification which can permanently transform a formerly productive landscape to an arid one that becomes increasingly intensive and expensive to farm.[7]. Typically farmers break up hardpan up with a subsoiler, which acts as a long, sharp knife to slice through the hardened layer of soil deep below the surface. List of Advantages of Intercropping. http://cropwatch.unl.edu/tillage/advdisadv. Thus when plowing parallel runs paralleling any contour the plow furrows soon deviate from a true contour. Demonstrations showed that contour farming, under ideal conditions, will increase yields of row crops by up to 50%, with increases of between 5 and 10% being common. Well-tilled seedbed. University of Hawai‘i - College of Tropical Agriculture and Human Resources. Increase Risk of Fungal Diseases. Alternatives to ploughing, such as the no till method, have the potential to actually build soil levels and humus, and may be suitable to smaller, more intensively cultivated plots, and to farming on poor, shallow or degraded soils which will only be further damaged by ploughing. As time passed, man discovered different ways of tilling and farming on different landscapes, including slopes that are notorious for soil erosion. 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 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. USDA NRCS Practice (330), Web. List, define, and describe the various methods of traditional sustainable agriculture: contour plowing, windbreaks, perennial crops, terracing, no-till agriculture, crop rotation, and strip cropping. It incorporates crop residues, solid manures, limestone and commercial fertilizers along with some oxygen. In contour plowing, the ruts made by the plow run perpendicular rather than parallel to the slopes, generally furrows that curve around the land an… Web. Some farmers may not have been fully aware of erosion damage and prevention. Media related to Contour farming at Wikimedia Commons, "Contour Farming for Cropland in the Pacific." "Desertification." Well-suited to dealing with slush and fluffy snow, these cutting edges are more popular in temperate climates. And the biggest disadvantage of agroforestry is the huge amount of time required to reap the yield products. [8] Reducing fertilizer loss not only saves the farmer time and money, but it also decreases risk of harming regional freshwater systems. Fish Substitute variety Atlantic cod Chilean sea bass … Penn State College of Agricultural Sciences, 2013. List of Disadvantages of Agroforestry. This method has disadvantages are: 1. What is the difference between contour ploughing and ... quoracdn.net. What are the Banaue Rice Terraces? Farming is one of the oldest and sustainable human activities. How does sustainable agriculture aid in soil conservation? Disadvantages:High soil moisture loss, destroys soil structure, compacts wet soil Then these sediments cannot form floodplains and beaches. Plows turn up the top soil and cuts existing root systems exposing the land to the drying sun, wind and the potential of being washed away by heavy rains. <, Hogan, Michael C., and GreenFacts. Contour ploughing helps to reduce soil erosion. This includes over 3000 lettuce, lots of chard, spring onions, beetroot, onions, shallots, spinach, parsley amongst others. Farming sites are often classified into five levels: insensitive, mild, moderate, high and extreme, depending on the regions soil sensitivity. Greater Income, Greater Yield Intercropping offers greater financial returns for a farmer. 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 maps are extremely useful for various engineering works: A civil engineer studies the contours and finds out the nature of the ground to identify. Dams hold back sediments that rivers carry. Timeliness considerations. Soil erosion prevention practices such as this can drastically decrease negative effects associated with soil erosion such as reduced crop productivity, worsened water quality, lower effective reservoir water levels, flooding, and habitat destruction. The US Department of Agriculture established the Soil Conservation Service in 1935 during the Dust Bowl when it became apparent that soil erosion was a huge problem along with desertification. This method is also known for preventing tillage erosion. How does sustainable agriculture improve soil … Disadvantages of Contour Plowing. [11] The proper combination of such farming methods can be determined by various climatic and soil conditions of that given area. Ed. But, rubber’s ability to contour to its plowing surface is its real claim to fame. On steeper slopes and areas with greater rainfall, a procedure known as strip cropping is used with contour farming to provide additional protection. The above runoff induced 4.7 t ha−1 soil loss from permanent bed, 7.6 t ha−1 from terwah and 19.5 t ha−1 from traditional ploughing. <, Reinhardt, Claudia, and Bill Ganzel. Suitable site for the project works to be taken up. Since the furrows run across the slope, these ditches... 2. <, Penn State College of Agricultural Sciences. Essentially, the main purpose of terracing land for farming is to reduce the velocity of water runoff and thereby soil erosion by breaking the length of the slope that runoff has available. Soil erosion due to improper land and plough utilization is possible. 2. Table 1. However, the Romans preferred cultivation in straight furrows and this practice became standard.[6]. This was one of the main procedures promoted by the US Soil Conservation Service (the current Natural Resources Conservation Service) during the 1930s. What are the advantages and disadvantages of the salad options shown in the photos in terms of convenience, food safety, and environmental impact? Ploughing leaves very little crop residue on the surface, which otherwise could reduce both wind and water erosion. Advantages: Less erosion and less fuel and labor required. Contour bunding has been widely adopted in Burkina Faso after it was suggested by British Oxfam worker Bill Hereford in the beginning of the 1980s. [5], The Phoenicians first developed the practice of contour farming and spread it throughout the Mediterranean. Terrace cultivation, or terrace farming, is one of the oldest types of land and water resource management for large-scale farming. Longsheng Rice Terrace definition/meaning staticflickr.com. Contour cultivation follows the contour lines of sloping fields. ( See Chapter 7 in Priority One History of Twentieth Century Soil Conservation and Keyline.). 100 million acres [405,000 km²] now in crops have lost all or most of the topsoil; 125 million acres [506,000 km²] of land now in crops are rapidly losing topsoil. Contour plowing is the farming practice of plowing across a slope following its elevation contour lines. Contour plowing was a method of plowing furrows that follow the curves of the land rather than straight up and down slopes. Ed. [10] Contour farming is most effective when used with other soil conservation methods like strip cropping, terrace farming, and the use of cover crops.
