Why Laser Leveling • Land looks leveled but even then wide topographic variation exists • Wide variability in crop yields at field/ village/ block/ district/ regional level • Better distribution of water • Water savings • Improvement in nutrient use efficiencies • Option for Precision Farming • Higher crop productivity

What is laser leveling? • Laser land leveling is leveling the field within certain degree of desired slope using a guided laser beam through out the field.
