It generally takes more labor for the first irrigation using contour fur- rows. Over a period, societies who embraced irrigation farming adopted this method of plowing and planting. When done right, this method reduces erosion by more than 50%. Shot on the DJI Phantom 4. Planning ahead helps the seemingly difficult contour farming to become easy. The practice has been proved to reduce fertilizer loss, power and time consumption, and wear on machines, as well as to increase crop yields and reduce erosion. This move was after a realization that soil erosion, just like desertification, was a threat to agricultural sustainability in the US. Contour ploughing is a well-established agronomic measure that contributes to soil and water conservation [] (see figure 1).The soil is ploughed along the contour instead of up- and downward (see figure). Strip cropping is good for long and steeper slopes while irregular slopes need more than a single key contour line. ... Other benefits include providing habitat for wildlife and in some regions the trees are harvested for wood products. 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. First, contour farming maintains soil fertility by preventing downwash of the fertile topsoil of a farm and consequently enabling betters yields. Since the furrows run across the slope, these ditches generally rim directly down slope. 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.

When done right, this method reduces erosion by more than 50%. Requires equipment turns on the field. 2. 6. Also, with natter irrigation grades, you have better control of the water and can reduce waste runoff at the lower end of the furrows. Contour plowing and crop rotation compare in many different ways, like they both use techniques to preserve soil. Contour plowing in Pennsylvania in 1938. Since then, contour plowing and other forms of conservation tillage have been reinstituted. Contour plowing, Pennsylvania, 1938 "Contour bunding", Catalonia, 2007. Contour farming captures twice the soil moisture and reduces soil erosion up to eight-fold. 7. As time passed, man discovered different ways of tilling and farming on different landscapes, including slopes that are notorious for soil erosion.

They're customizable and designed to help you study and learn more effectively. Some of the methods used to date include windbreaks, planting cover crops, planting grass on waterways, and contour cultivation among others. This method did not really take off during this time because farmers had little knowledge on erosion. Contour farming can have one crop on the farm or a mixture of several crops through strip cropping. Your equipment will be operated across the slope most of the time. Contour ploughing or contour farming is the farming practice of ploughing and/or planting across a slope following its elevation contour lines. Some farmers may not have been fully aware of erosion damage and prevention. But after furrow streams have once been adjusted to take care of fill and spike furrows, less labor is required. Easy brow contouring The Pros/Benefits/Advantages of Contour- Furrow Irrigation: 1. No need to register, buy now! 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. Contour farming is effective on slopes that have gradients between 2% and 10%. 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. Requires control of water in furrows. 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. pros of contour plowing. Natural, soft matte finish This arrangement of plants breaks up the flow of water and makes it harder for soil erosion to occur. Irrigation water flowing down sloping fields is wasting our basic soil and water resources at a very serious rate. So contour plowing helps prevent soil erosion. Requires protected head ditch- es and waste-water ditches. Reduces power costs. Contour plowing forms ridges, slows the water flow and helps save precious topsoil. You get a more even distribution of water over the field, making good growing conditions for all of the plants. An agricultural land fall under one of the following classifications; extreme, high, moderate, mild, or insensitive in terms of soil sensitivity. Ridging and adding new soils along planting rows are widely used in all kiwifruit production regions in China. Answer:Some advantages of contour plowing is that it focuses on preserving topsoil by reducing erosion from water runoff. 3. The deeper, slow-moving flows of water in the contour fur- rows soak into the soil quicker than the small, fast-moving streams used in down-slope irrigation. Reduces the erosion hazard in each furrow and permits you to irrigate efficiently land too steep for downhill furrows. Provides more uniform distribution of irrigation water.
