Demonstration test of smart rice transplanter

Smart rice planer (Variable fertilizer rice planter equipped with the soil sensor)

 On 5 June 2017, demonstration experiment of the smart rice transplanter (variable fertilizer rice planter equipped with soil sensor) jointly developed by Assoc. Prof. Eiji MORIMOTO; Department of Agricultural, Life and Environmental Sciences, Faculty of Agriculture and ISEKI & CO., LTD. was conducted in the farm field of the Agricultural Producers’ Co-operative Corporation INABAHAKUTO.

 This rice transplanter was developed as a part of Cross-ministerial Strategic Innovation Promotion Program (SIP). Plowing depth is measured with the ultrasonic sensor and the fertility of the soil is measured with the electrode sensor attached to the tire of the front wheel, and rice planting is done while adjusting the amount of fertilizer. Data is accumulated once in every one second, and this data can be checked with the free application.

 It is now possible to convert the work that relied upon farmers' intuition and experience into data, which is expected to solve the problems of Japanese agriculture such as conversion to large scale agriculture and transfer of know-how to new farmers.

 In the future, Lab. of Assoc. Prof. Morimoto will collect data of fertilization by using smart agricultural machineries and cutting by combine.

※This rice transplanter won 7th Robot Award in FY 2016.
