Coarsed textured sandy loams, loamy sands and sands are more susceptible to wind erosion than loams, silt loams, clay loams and silty clay loams. <\/li>\n<\/ol>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li><strong>Surface Roughness:<\/strong> \u0905\u0902 <mark style=\"background-color:var(--global-palette15)\" class=\"has-inline-color\">smooth soil surface is more erodable by wind<\/mark> than rough surface because of being less effecting in slowing the wind velocity near the ground. The rate of soil blow under a wind force varies inversly with the roughness of the surface. Optimum roughness for wind erosion is 5 to 12.5 cm. <\/li>\n<\/ol>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li><strong>Wind and Soil Moisture:<\/strong> Wind speed of about 12 Kph is necessary to initiate soil movement. Wind speed of 8 to 10 mps can carry 490 M t of soil per hectare on a 100 m front. Wind erosion can only occur when the soil surface is dry or only slightly moist, because surface tension holds the soil particles together when wet. <\/li>\n<\/ol>\n\n\n\n<ol start=\"4\" class=\"wp-block-list\">\n<li><strong>Vegetative Cover:<\/strong> Living or dead vegetative cover protects the soil surface from eroding action of the wind by reducing wind speed and preventing direct wind force from reaching erodable soil particles. <\/li>\n<\/ol>\n\n\n\n<ol start=\"5\" class=\"wp-block-list\">\n<li><strong>Organic Matter:<\/strong> It reduces wind erosion by increasing soil cohesion and creating a barrier on the soil surface. Organic matter binds soil particle together into stabble aggregates which resist eroding action of the wind.<\/li>\n<\/ol>\n\n\n\n<ol start=\"6\" class=\"wp-block-list\">\n<li><strong>Topography:<\/strong> Level land is more liable to wind erosion than rolling land as wind encounters less resistance. However, wind erosion on knolls and ridges is more as wind presses against such areas instead of flowing parallel to the surface. <\/li>\n<\/ol>\n\n\n\n<p class=\"translation-block\">\u092f\u0926\u093f \u0906\u092a\u0915\u093e \u0915\u094b\u0908 \u092a\u094d\u0930\u0936\u094d\u0928, \u0935\u093f\u091a\u093e\u0930 \u092f\u093e \u0938\u0941\u091d\u093e\u0935 \u0939\u0948 \u0924\u094b \u0915\u0943\u092a\u092f\u093e \u0928\u0940\u091a\u0947 \u091f\u093f\u092a\u094d\u092a\u0923\u0940 \u0915\u0930\u0947\u0902\u0964 \u0906\u092a <a href=\"https:\/\/agriculturereview.com\/hi\/agriculture-hashtags-for-instagram-facebook-twitter\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/agriculturereview.com\/agriculture-hashtags-for-instagram-facebook-twitter\" rel=\"noreferrer noopener\">\u092b\u0947\u0938\u092c\u0941\u0915<\/a>, \u0907\u0902\u0938\u094d\u091f\u093e\u0917\u094d\u0930\u093e\u092e, \u0915\u0942 \u0914\u0930 \u0935\u094d\u0939\u093e\u091f\u094d\u0938\u090f\u092a \u092e\u0948\u0938\u0947\u0902\u091c\u0930 \u092a\u0930 \u092d\u0940 \u090f\u0917\u094d\u0930\u0940\u0915\u0932\u094d\u091a\u0930 \u0930\u093f\u0935\u094d\u092f\u0942 \u0938\u0947 \u091c\u0941\u0921\u093c \u0938\u0915\u0924\u0947 \u0939\u0948\u0902\u0964<\/p>","protected":false},"excerpt":{"rendered":"<p>Erosion of soil by the action of wind is known as wind erosion.
