Management of two critical and important resources viz., Land and water in agriculture has become a challenging task for many reasons. In rainfed and irrigated agriculture, land development plays a key role because of undulating topography of the soil surface. It has a major impact on the germination, water saving and crop yield. Conventional methods of land levelling are more cumbersome and not so precise and repetitive in nature and mainly depend on the skills of the driver. A significant (20-25 %) amount of irrigation water is lost during its application at the farm due to poor farm design and unevenness of the field. | Laser land levelling- an engineering approach for scientific irrigation water management in irrigation command areas of Karnataka India
