Precision land leveling helps in controlling the emergence of salt affected patches, increasing cropping intensity and crop productivity in cultivable land area by 3-5 per cent, improving the crop establishment, reducing the weed intensity and saving the irrigation water. Laser leveling is the process of smoothening the land surface ± 2 cm from its average elevation by using laser equipped drag buckets to achieve precision in land leveling.
Precision land leveling involves altering the fields in such a way as to create a constant slope of 0 to 0.2%. This practice makes use of large horsepower tractors and soil movers that are equipped with global positioning systems (GPS) and/or laser-guided instrumentation so that the soil can be moved either by cutting or filling to create the desired slope/level.
