The Rural Development Administration held a demonstration event for the "improved deep-fertilizer injection device" at a test farm in Changnyeong, Gyeongnam, attended by around 100 garlic and onion farmers and related officials on the 30th. This demonstration event, which linked technology development with field dissemination, was a practical-oriented event held in collaboration with the Onion and Garlic Research Institute of the Gyeongnam Agricultural Technology Institute. The improved deep-fertilizer injection device is a rotary type that reflects the opinions of the farms and has improved performance to reliably supply fertilizer to a depth of 30 cm in the soil. In particular, it is designed to be used with various tractors currently in use by farmers, greatly enhancing its field applicability.
