Some of the methods used to date include windbreaks, planting cover crops, planting grass on waterways, and contour cultivation among others. There are a few options for planting a slope that include building a terrace, creating retaining walls or even making a rock garden. With a loader installed the maximum slope angle could be considerably less. Resources Soil erosion is a naturally occurring process that affects all landforms. As time passed, man discovered different ways of tilling and farming on different landscapes, including slopes that are notorious for soil erosion. Using this practice can: • keep valuable topsoil in place on sloping fields. All maps, graphics, flags, photos and original descriptions © 2021 worldatlas.com, Top European Countries For Organic Farming, Top African Countries For Organic Farming, Windbreaks And Shelterbelts: Wind Erosion Control In Farming. Farming on a Slope. Planting on a slope might seem like a mountainous endeavor. SALT is a package technology of soil conservation and food production, integrating differing soil conservation measures in just one setting. If you are installing a gate across a slope, you must plan for it to open toward the downhill side only. Now that you are familiar with the ethics and principles of Permaculture Landscape Design, and have sketched out the Zones and Sectors for your property plan, its time to take it 3-D!. The early promise of molecular farming was based on three perceived advantages: the low costs of growing plants, the immense scalability of agricultural production, and the inherent safety of plants as hosts for the production of pharmaceuticals. In addition, the book noted that the trend had other consequences including, low food supply, massive loss of jobs and properties, and increased commodity prices. Contour farming also creates water breaks that reduce the formation of gullies and rills when a place experiences heavy rains and water run-off which is the leading cause of soil erosion. • reduce labor and make harvesting easier. To control this movement of rainwater, Keyline Design uses “off contour” drift when tilling furrows. Summary 10. Few potential forest farming sites in the Northeast are on flat ground. Maintenance rectifies unforeseen mistakes as well as repair areas that elements of nature destroyed. This method did not really take off during this time because farmers had little knowledge on erosion. Contour farming is popular on all the inhabited continents of the world. Farm tiles function the same with a slope 8, flat or anything in between. The consequences of that trend, according to the yearbook, could have been large-scale desertification and permanent transformation of the agricultural landscape to an arid area. Contour farming is most effective on slopes between 2 and 10 percent. Tillage Erosion 7. With the reduced loss of fertility comes the reduced use of fertilizer and a reduced cost of purchasing fertilizers. When the slopes are steeper and rainfall is greater, strip cropping becomes ideal in contour farming because this provides an extra layer of protection. Once you know what plants grow on slopes, you can use this knowledge to your benefit and plan a garden that both thrives and helps stabilize the hillside. Contour cultivation (contour farming, contour plowing, or contour bunding) is a sustainable way of farming where farmers plant crops across or perpendicular to slopes to follow the contours of a slope of a field. An agricultural land fall under one of the following classifications; extreme, high, moderate, mild, or insensitive in terms of soil sensitivity. And at times, we’ve run a CSA here where we fed 18 families off of this space. See more ideas about hillside landscaping, sloped garden, sloped backyard. In many countries, both small-scale subsistence farmers and largescale farmers try to overcome slopes through this method. The practice of contour farming, though good, is not ideal in all slope and climate conditions. As societies evolved from simple to sophisticated lifestyles, human beings began to till land and farm in order to produce their own food. In getting the key line, farmers should use a contour gauge or a hand level and thereafter plant parallel to the key line. Urban Farm Design with Scott Murray. This will minimize … A 20 degree slope is a 36.4% grade. You plant that area and get the vegetation going before you plant the area alongside. Strip cropping is a type of contour farming where farmers plant different crops in alternating strips of different levels. Definition of Contour ploughing or contour farming is the farming practice of ploughing and or planting across a slope following its elevation contour lines in the Definitions.net dictionary. Grassed waterways are also important, especially where there is a high concentration of runoff water while grassed strips come in handy where the contour lines are too sharp for farming equipment to plow. Plowing and planting across slope contours create man-made water breaks that not only allows enough time for the water to enter the soil, but also to settles the topsoil without washing it down the slope. However, there are a variety of ways to approach foliage on a hill or slope. Most farmers reported between 5% and 10% increase in yields although demonstrations under ideal conditions indicated that the yield can increase by wider margins of up to 50%. kÒÈ^Ѫܨ69•&²Œ—k ܕª¦˜\tÜFL¼v«Ef‰2œQ¬Š÷6š©ÞvnP2‚´îçÛ^µ§¬q~b® You need to flatten it first". We’re on our Edge of Urban Farm in Vista, California and it’s a 1.2 acre site that we’ve developed about three-quarters of an acre as a micro farm. Strip cropping is good for long and steeper slopes while irregular slopes need more than a single key contour line. The Keyline Design looks at how specific topographies link to water flow for an optimum use of water on a farm. This not only makes it easier for you but also prevents problems with erosion. The technology is now >30 years old. Sloping the land toward the south catches sunlight and water, but too much slope causes erosion. This move was after a realization that soil erosion, just like desertification, was a threat to agricultural sustainability in the US. Water Erosion 2. This gentle slope—descending 1 foot over a length of 100 feet—catches a little more sunlight. Meaning of Contour ploughing or contour farming is the farming practice of ploughing and or planting across a slope following its elevation contour lines. Divert the Flow. Terrace farming is commonly used in Asia by rice-growing countries such as Vietnam, Philippines, and Indonesia. Within the next four years, the new agricultural techniques reduced soil erosion by approximately 65% although drought prevailed. Contour farming can have one crop on the farm or a mixture of several crops through strip cropping. This practice will be less effective in achieving the stated purpose(s) on slopes exceeding 10 percent and in areas with 10-year, 24-hour rainfall of about 6.5 inches. Yeoman devised the Keyline Design that guides contour farming in order to get some minimum ideals. So you cultivate your hillside in patches rather than planting the whole hillside. Furthermore, water retention improves soil quality, irrigation, and water conservation thus reducing labor that would have gone into physical fetching of water. Some of the methods used to date include windbreaks, planting cover crops, planting grass o… Wind Erosion 5. Most compact tractors are not capable of operating safely on sideslopes beyond 20 degrees and some are much less. To roll out a massive campaign for contour farming, the Soil Conservation Service partnered with federal institutions, state governments, universities, and communities in order to promote the method to both small-scale and large-scale farmers as well as to research more on how to achieve the best results with the method. When done right, this method reduces erosion by more than 50%. For example, a farmer may plant different crops on different strips of land during alternating farming seasons, such as rotating strips of legumes and corn enables the corn to use nitrogen that the legumes left in the soil. To better understand the ideal combination of techniques, farmers should have in mind the climate of the region, soil condition, and the angle of the slope. Terrace farming is a method of farming whereby “steps” known as terraces are built onto the slopes of hills and mountains to be used for crop cultivation. endstream endobj 319 0 obj <>stream. • slow water down and let it soak into the soil. Experts encourage contour farmers to use additional soil and water conservation techniques to supplement the former in order to yield the best results. In North America, both the US and Canada have extensive farms under contour farming. It is possible to divert the flow of water drainage away from your slope. Institutions such as the University of Nebraska rolled out innovative campaigns that challenged farmer perceptions and encouraged them to do contour farming. As time passed, man discovered different ways of tilling and farming on different landscapes, including slopes that are notorious for soil erosion. Though labor-intensive, the method has been employed effectively to maximize arable land area in variable terrains and to reduce soil erosion and water loss. The early promise of molecular farming was based on three perceived advantages: the low costs of growing plants, the immense scalability of agricultural production, and the inherent safety of plants as hosts for the production of pharmaceuticals. 1. Molecular farming can be defined as the use of plants to produce recombinant protein products. Some examples: A 15 degree slope is a 26.8% grade. Slopes affect crop performance by influencing runoff and erosion potential, soil moisture content, soil composition, air drainage and the duration of exposure to direct sunlight. by steep slope and to assess agricultural experts ¶ attitude towards impact of terrain factor on the generic farming activity. In 1934, the Yearbook of Agriculture wrote that “more than 35 million acres of previously cultivated fertile land were destroyed and could no longer yield enough crops.” Furthermore, the book also noted that 100 million acres of the then cultivated land had lost most or all of the topsoils that contained humus and over 125 million acres of the then cultivated land were losing their topsoil in an alarming rate. contour farming on their farm. Slope. You can do … In heavy rains we are protected from floods, in dry times we can use gravity to our advantage in irrigation, when frost settles in the valley come fall we can stretch out an extra week or so before the frost makes its way uphill, and the Southwest orientation magnifies the sun’s effect, warming our fields from spring through fall. They are too steep for most agricultural systems, and any animal impact will significantly degrade slope stability. In the design, contours ought to be made in specific ways to control rainfall runoff and maximize irrigation of undulating land during fast floods without building terraces. Click here for ideas on choosing plants for sloping areas and how to maximize this difficult planting terrain. To learn more about protecting your sloping farm land from water damage, read So I chose a slope of 1 percent. Flatlands are more suited to strip tillage that will aid in soil warming and drying, compared to sloped fields that are more suited to a no-till approach, according to Mark Licht, Iowa State University … P.A. The farmers in Phoenicia (land of the palm trees) helped spread contour farming throughout the Mediterranean region and eventually many farmers in present-day Israel, Lebanon, Syria, Gaza, and parts of Turkey adopted the method, however, the Romans at the time preferred straight furrows. The nitrogen fixing trees are thickly planted in double rows to make hedgerows. A 30 degree slope is a 57.7% grade. In a bid to control soil erosion, the US Department of Agriculture established the US Soil Conservation Service, currently the Natural Resource Conservation Service, and started promoting contouring in the 1930s. The most commonly used supporting cropland practices are cross-slope cultivation, contour farming and strip cropping . Less than 25% slope is the place for terracing, swales, and intensive food/animal production. Interview with Scott Murray at Edge of Urban Farm on Urban Farm Design. Terrace farming prevents the washing away of soil nutrients by the rains. As the campaign had anticipated, farmers reported using less fertilizer, reduced erosion, and less energy and resource use. First, contour farming maintains soil fertility by preventing downwash of the fertile topsoil of a farm and consequently enabling betters yields. For contour farming to be effective, the resulting curved furrows around the slope ought to be on equal levels. Attempting to sow seeds on a greater slope results in a message "The ground is not flat enough for crops to grow. 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. For effective yield, farmers should perform regular check and maintenance. The best solution for hillsides is to plant your vegetables across the slope using contour rows, terraces, or raised beds. Procedure for Using the USLE. International organizations such as Oxfam UK and FAO encourage farmers in parts of Africa like Burkina Faso to adopt contour farming. This arrangement of plants breaks up the flow of water and makes it harder for soil erosion to occur. Terrace cultivation, method of growing crops on sides of hills or mountains by planting on graduated terraces built into the slope. Basically, SALT is a method of growing field and permanent crops in 3-5 m wide bands between contoured rows of nitrogen fixing trees. Yet it’s not steep enough to cause seeds and soil to be washed away. • improve irrigation systems and conserve water. Effects of Water Erosion 4. Based on the soil texture, determine the K value (Table 2). Conservation Measures 9. Over a period, societies who embraced irrigation farming adopted this method of plowing and planting. This method equally prevents soil erosion and can improve soil fertility through crop rotation. One common solution to a long slope length is planting in terraces. Soil type matters, as does slope and drainage of the field. The trick is to cultivate only a very small area at any one time on a steep slope. Molecular farming can be defined as the use of plants to produce recombinant protein products. Slope was not seen as a negative, unless, of course, for areas that we considered “too steep.” How steep is too steep? Even with our challenges, the slope of our land more often offers advantages. Other benefits are and time efficiency and reduced use of machines which in turn reduce the wear and tear. Effects of Wind Erosion 6. This system also observes that at the end of a contour, the land is always steeper on one side than the other leading to furrows deviating from the true contour when plowing parallel to a contour, thus making rainwater flow to the steeper side and increase erosion. Slope Farming is a research project aimed at developing a holistic land use management system for the productive restoration, conservation and improvement of land and water resources and the overall ecosystem. Secondly, the area must be receiving a given amount of rainfall in a given period. Contour farming is effective on slopes that have gradients between 2% and 10%. In most cases, rainwater washes farming fertilizers downstream and consequently contaminating freshwater systems. On slopes with no contours, water runoff quickly without the soil properly absorbing it and carrying the top fertile soil with it, therefore, leaving a non-fertile land up the slope. Such supplements include strip cropping, use of cover crops, use of windbreaks, grassing waterways, and building terraces among others. The technology is now >30 years old. Farming is one of the oldest and sustainable human activities. The practice is not well suited to rolling topography having a high degree of slope irregularity because of the The classification of the farming systems of developing regions has been based on the following criteria: available natural resource base, including water, land, grazing areas and forest; climate, of which altitude is one important determinant; landscape, including slope; farm size, tenure and organization; and During the time of Thomas Jefferson’s term, farmers called this system “horizontal plowing” and his relative, Randolph, developed a plowing technique that caught water in ridges of upturned land unlike plowing down like roof shingles. Effects of Tillage Erosion 8. As societies evolved from simple to sophisticated lifestyles, human beings began to till land and farm in order to produce their own food. Even though we strive to create a ne plus ultra/nonpareil wine, practicality must enter into our decision-making. For example, the slope can be level EW and 8-steep NS, or it can be 4-steep EW and 4-steep NS, etc. Planning ahead helps the seemingly difficult contour farming to become easy. Apr 14, 2019 - Explore Aken Koh's board "steep slope farming", followed by 198 people on Pinterest. This practice eventually spread to different parts of Europe who also introduced contour farming to some of their colonies. myself I'd probably start with fruit trees, if the slope is too steep you might want to put a swale below the tree down the slope, and if you are planting ladder harvest trees, might want to make some flat ground for the ladders..so you don't tumble down the hills. Forms of Water Erosion 3. Planning involves surveying and estimating the number of contour lines needed and if other methods would be necessary to supplement. Randolph’s invention amazed Jefferson because of improved water retention capability. This paper an alyses differences and similarities between Lithuanian rural elderships affected by steep slope constraint (i.e. During the period of Ancient Greek, a thalassocratic ancient Semitic civilization, the Phoenicians, who originated from the Eastern Mediterranean, practiced some of the earliest forms of contour farming. Secondly, contour plowing increases the soil’s water retention ability to ensure that enough water soaks into the soil for good health of the plants. 2 Essential Tips For Installing A Farm Gate On A Slope If you are installing a gate so that one end the of it is higher than the other, the hinged end should be the lower end. The degree of slope affects the type of irrigation you can use, and the slope of the land determines which way the rows run in your garden. Determine the R Factor . Examining Crops Farming is one of the oldest and sustainable human activities. • improve the appearance of the farm. In summary, the method tends to promote sustainable agriculture and reduce most of the ills associated with soil erosion on slopes such as habitat destruction. The first ever recorded contour farming in the US came at the turn of the nineteenth century but the country did not fully embrace this method until during the twentieth century. A recent decision to extend 5.8 million hectares of land designated as 'low slope' to 9.6 million hectares is causing trouble for affected farmers. 7 £ (15%) slope gradient) with the subsequent evaluation in selected agronomical Other techniques to include are growing bush or tree borders across the slopes (vegetative barriers), residue management, and mulching to protect the soil.
