Abstract

The objective of this paper was to provide the development of on-the-go soil sensor for rice transplanter, particularly from a perspective of precision agriculture applications. Ultrasonic sensor, electrodes and platinum resistance thermometer were employed for topsoil depth (TD) and apparent electrical conductivity (EC_a) measurement. Soil fertility value (SFV) defined as new soil parameter, which consisted of EC_a / TD. The results of field test revealed that the developed equipments could measure the TD (R² = 0.999), and the SFV had a strong relationship with measured EC (R² = 0.937).
