Scheme for Implementing Regionally Based Maximum Nutrients Loading System

The increasing nutrient excess pollutes surface as well as underground water. In addition, it causes soil acidification, deteriorates the agricultural ecological system, and increases greenhouse gas emission, thereby generating substantial amount of social costs. As a decisive measure to find out the nutrient balance status by region and properly resolve the nutrients surplus problem in a cultivated land, the Korean government announced its plan to introduce the Regionally Based Maximum Nutrients Loading System (RMNLS) from 2007. The objective of this study is to map out detailed scheme for implementing the RMNLS in a full scale. The study suggests the preconditions for smoothly operating the RMNLS. They include the building of relevant statistical database and nutrients accounting system for calculating regional nutrient balances, the setup of a livestock unit to accurately calculate livestock manure amount, the establishment and operation of the Monitoring Team of Maximum Nutrients Loading System and the preparation of laws and institutions for implementing the RMNLS.
