In India, currently more than 5,000 laser levelers are in use in Punjab, Haryana, Western UP, Bihar, Madhya Pradesh, Gujarat, Tamil Nadu, Karnataka and other states

Uneven soil surface has a major impact on the germination, stand, and yield of crops due to inhomogeneous water distribution and soil moisture. Therefore, land leveling is a precursor to good agronomic, soil, and crop management practices.

Traditionally farmers level their fields using animal drawn or tractor-drawn levelers. These levelers are implements consisting of a blade acting as a small bucket for shifting the soil from higher to the low-lying positions. It is seen that even the best leveled fields using traditional land leveling practices are not precisely leveled and this leads to uneven distribution of irrigation water. An estimate shows that 30 to 50% of water is wasted when land is not properly leveled. The advanced method to level or grade the field is to use laser-guided leveling equipment.

Working Principle of Laser Land Leveler: -

Laser land leveling is leveling the field within certain degree of desired slope using a guided laser beam throughout the field. The system includes a laser-transmitting unit that emits a laser beam that travels in a perfectly straight line. Beam received by a laser receiver that senses the light and sends signals to a control box to activate an electro hydraulic valve which raises and lowers the blade of a scrapper & eliminates all undulations tending to hold water. Laser transmitters create a reference plane over the work area by rotating the laser beam 360 degrees. This is all accomplished automatically without the operator touching the hydraulic controls. There are two types of land leveling—

1 To provide a slope which fits a water supply

2 To level the field to its best condition with

minimal earth movement and then vary the water

supply

Benefits of precise land leveling:-

Saves irrigation water more than 35 % due

to uniform distribution

Increase productivity up to 50 % due to

good germination and growth of crop

Increase in field areas by 3.5 %

Reduce farm operating time by 10 %

Increase in nitrogenous efficiency by 7%

Precise level, smoother soil surface & better

top soil management

Uniform moisture environment for crops

Heavy savings in labor cost and efforts of hiring

Reduces greenhouse gas emission

Reduced weed in the field

Assist top soil management

Saves fuel/electricity used in irrigation

Why do people do precise land leveling using laser technology worldwide?

Land leveling is important in terms of saving land, saving water, and saving labor. It improves drainage and helps avoid crops damage. It also helps in efficient use of other farm resources.

Precision land leveling increases the water application efficiency and consequently the yield of crops. At first, a tractor drawn soil scrapper is used to remove small undulations and irregularities in the field. The process of surface smoothing can best be performed with the help of laser land leveler. While the equipment has a higher initial cost but it reduces the operation cost and ensures the field level to desired gradient to improve yield and conserve irrigation water, therefore reducing the total cost of ownership.

For the precision land leveling using laser assisted land leveler equipped with drag scrapper is a process of smoothing land surface within± 2 cm of its average micro-elevation.
