Laser land levelling
It is the process of
leveling the land surface at an accuracy level of ± 2 cm from its mean
elevation by using laser-equipped drag buckets. Besides, this method creates a
constant slope of 0-0.2% throughout the field, for which, irrigation water
spreads uniformly in every part of the field with negligible loss from run-off
or water-logging.Large horsepower tractors and soil movers equipped with
global positioning systems (GPS) and/or laser-guided instrumentation are used
in this method.The soils are moved either by cutting or filling to make the
land surface well leveled.Laser leveling increase water saving by approximately
20-25%, increases approximately 3 to 5% of cultivable land area, reduce GHG
emission and increases the yield of crops.
