Given continuous needs for a public duty of agriculture and rural area, an effort to improve nutrient management in agricultural sector is strongly required. As a measure to solve these problems, Korean government (MAFRA) introduced the promotion policy called as “Agro-Environment Conservation Program (AECP)” in 2018 and has expanded 5 projet sites in 2019 from 3 in 2018. The program has a variety of agricultural activity to conserve soil, water, air, ecology and landscape. Of those, the nutrient input activity which is one of sub-activities is closely involved in not only crop productivity but also water quality and air pollution. Therefore, in order to lead a soft landing of AECP, it is essential to evaluate the conservation effects in a scientific point of view. In this respect, we focused on evaluating the effect of recommended nutrient input activities, standard fertilization and soil test fertilization, on rice productivity and nitrogen balance. The effect of nutrient management which is explained by rice yield and nitrogen balance was estimated with the combination of soil characteristics and rice varieties. Rice yield by recommended fertilization was 654 kg per 10a, 6% lower than control, but there was no statistical significance. By contrast, nitrogen balance was 4.7 kg lower, which means great improvement, in the recommended than the control. Conclusively, the recommended fertilization like soil test fertilization is expected to be useful as a measure to reduce nutrient balance, to ensure crop productivity, and finally to perform a public role of agriculture.
