Development of localized fertilization system for analyzing robustness of plants against environmental change

Abstract

We are developing a self-propelled fertilizer machine, which carries concentrated liquid fertilizer, moves on water, and ejects the liquid fertilizer to a paddy rice if necessary. By using a prototype self-propelled fertilizer machine, the rate of forced diffusion of pseudo-fertilizer liquid was estimated. We have confirmed that the fertilizer has been spread 20 cm within 2 seconds. The method of forced diffusion can potentially be fast enough to manure to a paddy rice.
