LAND LEVELER

LAND LEVELER

This Best Management Practice is used to increase the uniformity with which water is applied to an irrigated field. The term “Land Levelling” generally applies to mechanize grading of agricultural land based on a detailed engineering survey, design, and layout. In only a few special situations does the final product of land levelling result in a level field. Normally final slopes are up to three percent for furrow irrigation and up to two percent for border irrigation. Most land levelling is done using a laser-controlled scraper pulled by a tractor. The laser is set to pre-determined cross and run slopes, and the scraper automatically adjusts the cut or filled land over the plane of the field as the tractor moves. 

Land levelling is typically used on mildly sloping land, whereas contour farming is used to farm on modest slopes and terrace farming is used for steeply sloping land. Land levelling is primarily used by agricultural producers using surface irrigation methods (furrow, border, basin, or flood) or by those wishing to improve surface drainage of their non-irrigated field. 

Land levelling work falls into two general categories: 

1. Large scale land shaping prior to cultivating newly irrigated land or land that has never been graded

2. Floating of a field prior to preparation of seed beds or borders.

Land Leveller consists of three units namely Base Unit, Bucket Unit and CPU Unit.
