No-till Farming System: Research Direction and Outlook in Korea

Abstract

No-till farming system has been extensively studied all over the world as the effective method for maintaining the soil fertility. The general advantages of this system have been well known for reducing the labor, fuel, machinery, and irrigation cost as well as for increasing the soil quality through soil aggregation, water infiltration, microbial population and etc. Recently, it becomes more popular with the increase of interest on sustainable agriculture, especially because of its higher carbon sequestration potential compared to conventional tillage. Crop residue management should be essentially included to look forward to achieving the positive effect on reduction of greenhouse gas. Nonetheless, there are also negative opinions on effect of no-till farming system. For example, some researchers reported that soil physical properties were not improved by no-till under certain soil and climatic conditions. This means no-till farming systems were strongly affected by the soil characters and climatic conditions. Therefore, the researches to meet the specific-regional characters are greatly needed in order for no-till farming system to successfully settle in Korea. The objective of the review article is to present the future direction and perspective on no-till farming system in Korea. For this purpose, we summarized the results of domestic and foreign researches about no-till farming system until now. Specifically, the chapter on foreign research consisted of four parts: positive and negative effects, the effect in paddy soil, and latest research direction (2012-2013) of no-till farming systems. Whereas, review for domestic researches was divided into two main parts: paddy and upland soils. In the final chapter, the priorities for the optimum conservation tillage in Korea were discussed and proposed through the previous researches.

Changes of Chemical Properties and Correlation under No-tillage Silt Loam Soil with Ridge Cultivation of Plastics Film Greenhouse Condition

“…오랜 역사를 지닌 쟁기는 산업화가 고도화되기 전인 17세기까지 사용되어 왔으나 (Derpsch, 2004;Kang et al, 2013), 현대 에는 생산성 향상과 농가소득 증대를 위한 대형농기계의 사 용과 시설재배의 경우 2~5회의 다모작 (多毛作) 재배로 인 한 많은 문제점이 발생되고 있다 (Kim et al, 1997b;Yang et al, 2014). 특히 강한 관행적인 기계경운(conventional tillage)은 토양 비옥도와 보수력 및 토양구조의 안정성을 감소시키고 물과 바람에 의한 침식을 쉽게 하며 작물의 생 산성을 유지하기 위한 비료 투입량을 증가시키는 원인이 되 고 있다 (Shokati and Ahangar, 2014;Du Preez et al, 2001;Roldan et al, 2003;D'Haene et al, 2008).…”

Life Cycle Assessment of Greenhouse Gas Emission of Rice Cultivation under Minimum Tillage in the Gimje, South Korea

“…It is expected that greenhouse gas emission reduction strategies in the agricultural sector could be reduced by applying minimum tillage to cropland and reducing the use of agricultural material. (Kang et al, 2013;Kim et al, 2016b). 또한 벼 이앙 시 모의 이식이 불안정하여 모가 물에 뜨는 문제가 생기기도 한다 (Kang et al, 2013;Kim et al, 2016b;Gwon et al, 2022).…”
