1 LASER Land Leveling in Rice Farming Julian F. Cacho BAE 4213 April 28, 2004

2 Overview  LASER  LASER Leveling System  How LASER Leveling Works  Benefits of LASER Land Leveling in Rice Farming  Limitations of LASER Land Leveling  Possible ways to overcome the limitations

3 LASER Defined:  Light Amplification by Stimulated Emission of Radiation  Light of special properties  Lasers amplify light Radiation coverage at wavelengths ranging from IR to UV and even Soft X- ray range (XUV)  XUV (10 nm – 30 nm) (

4 LASER Leveling System  Laser Transmitter  Laser Receiver  Electrical Control Panel  Twin Solenoid Hydraulic Control Valve

5 LASER Transmitter - Sends the LASER beam rapidly in a circular manner

6 LASER Receiver (Omni-directional) - Intercepts the LASER beam

7 Electrical Control Panel - Accepts and Interprets the signal from the LASER receiver

8 Twin Solenoid Hydraulic Control Valve - Raises or lowers the bucket

9 Benefits of Precise Land Leveling  Increases Yield  Reduces Weed Problems by even water distribution  Increases Opportunity to Use Direct Seeding  Increases Water Use Efficiency  Other benefits

10 Yield Increase Table 1. Results of Land leveling experiments conducted by CIAP in Cambodia, YearRice Yield (t/ha) Leveled FieldsUnleveled Fields (CARDI) Average Average Increase = 24% or 530 kg/ha

11 Reduces Weed Problems by Even Water Distribution  Improved water coverage - reduces the weed by up to 40% (Rickman, 2002)  Reduction of time for crop weeding (Rickman, 2002) - from 21 to 5 labor days/hectare - 75% decrease in labor required for weeding

12 Increases the Opportunity to Use Direct Seeding - Direct seeding reduces labor by approximately 30 person- days/hectare

13 Increased Water Use Efficiency  Reduction in time and water required to irrigate the field - 25 to 50 % less water to flood the field (Coblentz, 2000)

14 Other Benefits  Highly Accessible and Inexpensive Input Data - topographic map -internet, local agricultural offices  Re-leveling takes 5 to 10 years (Rickman, 2002)

15 Limitations of LASER Land Leveling  High Cost of the equipment/LASER instrument  Need for Skilled operator to set/adjust laser settings and operate the tractor  More efficient for regularly sized and shape field

16 Possible Ways to Overcome the Limitations in the Third World Countries  Government Intervention - precision land leveling services on a subsidized rental basis - The Government of Punjab, India charges services by Rs. 150/hr = $3.4/hr = Php187.5/hr  Intervention of Farmers’ Cooperatives and Other Farmers’ Associations
