| Abstract | The effect of no-tillage and conventional tillage practices on the nitrous oxide (N$_{2}$O) emissions from the upland soil was evaluated in the cultivation of soybean in the temperate climate from June 2014 to September 2015 in Korea. In addition, we investigated the links between N$_{2}$O emitted from field soil and different kinds of fertilizers. An experimental plot was composed of two main sectors that were no-tillage and conventional tillage, and then they were subdivided into four plots according to types of fertilizers: CF, chemical fertilizer, LP, liquid pig manure, HV, hairy vetch, and NF, non-fertilizer. The monthly averages of N$_{2}$O emissions were significantly different from each other during the growing seasons of soybean; in July, N$_{2}$O emission was significantly the highest, whereas, in September, its emission was the lowest (LSD, p = 0.05). In 2015, compared to those treatments in conventionally-tilled soils, the cumulative N$_{2}$O emissions in NK, CF, HV, and LP of no-tilled soils were reduced by 20, 28.7, 35.7, and 28.1 %, respectively (LSD, p = 0.05). It was shown that N$_{2}$O emission was significantly reduced in the different fertilizer treatments of no-tilled soils, compared to those of conventionally-tilled soils, respectively. Furthermore, the cumulative N$_{2}$O emission in no-tilled soils was reduced by 0.03–0.09 kg N$_{2}$O compared to that in tillage soils. It was found that soil N$_{2}$O emission was about 11 % less in LP than in CF. Results obtained from our study indicate that the use of no-tillage practice and liquid pig manure, rather than tillage practice and chemical fertilizer, can decrease the N$_{2}$O emission. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
