![]() ![]() The procedure involves first determining the centroid of the field as per the procedure explained in section 17.3 of lesson 17 and then determining the average elevation of the field. This method is feasible whenever it is required to grade the field to a true plane. The plane method is the most commonly used method of land levelling design. The procedures adopted to use these methods are briefly presented in this lesson. These methods are: Plane method, Profile method, Plan inspection method and Contour adjustment methods. ![]() There are several methods for land leveling design. Hence for land leveling design should be done properly. Hence it is essential to estimate locations and volumes of cuts and fills, maintain proper cut-fill ratio by minimally affecting the crop production and at the same time involving the less cost for land leveling. Further farm machineries movement compact soil and disturb soil pores and thereby reduces water movement through side. However, major topographical changes in the process of land leveling may reduce crop production in the cut areas or additional soils may have to be added in cut areas for improving soil fertility. A properly leveled land can be properly irrigated and excess water can be drained out. This also reduces labor requirement for water application. A precise land leveling improves irrigation and energy efficiency.
