Monitoring of Rice Growth Status by Using Unmanned Aerial Vehicle and Relationship with Soil Nutrition

Research and development on smart agriculture is being promoted to solve the problems of efficiency and labor saving of agricultural work. This paper describes relationship between the results of monitoring plant height and NDVI using UAV and soil nutrients. Focusing on the fact that the distribution of NDVI is different even in one rice field, the relationship with soil nutrients (phosphate, potassium, calcium, magnesium) was investigated. As a result, it was found that the activity of paddy rice is increased by absorbing phosphate in the soil.
