This paper examines how the grasslands were formed in the 1970s in South Korea, where the dairy industry was almost non-existent until the mid-20th century. Making grasslands was considered as a significant method in South Korea to cultivate unused lands and reduce management expenses for the dairy farms. The Korean government focused on developing grasslands using authentic Korean wild grass. However, the Korea Dairy Company and foreign experts concentrated on implementing imported pasture plants and making efforts to adapt them to South Korea’s environment. In this transition, a set of efficient practices was devised, which took into account South Korea’s hot and humid summer climate, the limited amount of farming area, and the characteristics of wild grass. Technical specialists educated farmers on how to apply those practices to maintain grasslands. As a result, there emerged a distinctive form of grassland management system, different from pasturage, which was generally used by other leading countries in the dairy industry like New Zealand and Denmark. Looking into South Korea’s development of grasslands, this paper shows how the dairy industry has settled using a technical training system focused on the land and farmers, rather than innovative scientific research achievements and mechanization.
