Laser leveling

Laser-guided leveling systems are commonly used in agricultural applications in Australia, Japan, and the United States. Currently, lesser developed country have started using laser-guided systems for land leveling of rice production areas. Using this technology results in a much more level field. Accuracy can be improved by as much as 50% compared to other leveling methods.

The benefits of laser leveling over other land leveling methods include the following:

- More level and smooth soil surface
- Reduction in time and water required to irrigate the field
- More uniform distribution of water in the field
- More uniform moisture environment for crops
- More uniform germination and growth of crops
- Reduction in seeds, fertilizer, chemicals and fuel used in cultural operations
- Improved field trafficability (for subsequent operations)

This video explains the concept of laser leveling and its benefits, as shared by Vietnamese farmers who have tried and adopted laser leveling in their rice fields. The video also shows the current efforts of the International Rice Research Institute (IRRI; http://irri.org ) in working with national partners and donors (Swiss Agency for Development and Cooperation - http://www.sdc.admin.ch - and Asian Development Bank - http://www.sdc.admin.ch ) to promote the technology in Cambodia.  Aug 29, 2014, 5:49 PM Reianne Quilloy (IRRI)
